Fun fact: the KNS piston for the short ACE is already external adjustable. Since the piston is so short, you can just pull the charging handle all the way back and adjust it from the ejection port. 🤠
I recommend trying this gun with a Krinkov-style muzzle device. The cone at the end serves the purpose of directing muzzle blast downrange in addition to hiding flash. There's a reason it's designed the way it is. It also cuts down on muzzle rise. You can also try a muzzle brake that comes with a blast can to send the muzzle blast forwards. The blast can will also capture the sideways flash so you the shooter won't see it. I had one of those on a 7.62x39 AR and it worked great.
4:30 You guys completely missed the fact that the KNS piston for the 8" galil ACE uses a different type of adjustment. It can be adjusted through the ejection port, without ever removing the dust cover.
So you can actually adjust the KNS Piston on these galil short bois just by pulling the bolt all the way back. It allows you to reach the adjustments from the ejection port.
7.62x39 and .300 Blackout are functionally identical rounds. They have the same trajectory and same velocities (within ~50 FPS) using the same bullet weights and barrel lengths. Both are available in 123-grain supersonic and 220-grain subsonic (Brown Bear made 220 grain 7.62x39, as do other companies), as well as 90-grain. And 123-grain (an oddly specific weight if you're making a whole new cartridge, but the most common weight for 7.62x39) is the most common supersonic bullet weight for both. While almost no one will admit it, the true point of .300 Blackout is to mimic 7.62x39 in a cartridge that more reliably feeds in the AR15. This is proven by the simple fact that they maintain nearly identical velocities at the same bullet weights and barrel lengths, across the board. Someone figured out 7.62x39 subsonic performs well and decided to copy it.
Nope. This is not true. As someone who fires a lot of 7.62x39 and .300 blackout, while the terminal ballistics and velocities are very similar, .300 blackout has slightly less recoil and slightly lower muzzle velocities than 7.62x39. However it also has a better bullet design that gives the round a superior bullet coefficient resulting in a more accurate round at 300 meters. Both subsonic and supersonic rounds are also optimized to shoot well out of short barrels. So they create less wear and tear on an AR bolt assembly group compared to a short-barreled 5.56mm. I know because I have both a 7" 5.56mm upper and a 7" .300 blackout upper. Also the .300 blk round was developed because 7.62x39mm rarely worked reliably in AR platforms. So overall, I while I do LOVE my AK-47 and SKS rifles, I found the .300 Blk round to be superior in short barreled rifles in terms of less recoil and much less muzzle flash due to the faster burning powders used in most commercial.300 blackout rounds. So I'll keep shooting my full size AKs and SKS's, but for home defense CQB, .300 blackout 110 grain V-max rounds from a 7" barreled AR is absolutely devastating. They also make for an extremely compact and lightweight hog hunting firearm.
@@wigon You're about16? Nothing you've said makes sense. 2 identical rounds out of identical barrel lengths moving at the same velocity would have nearly identical recoil impulses. Muzzle flash has nothing to do with the projectile, and more to do with the type of powder. Vmax bullets are interesting, but why would you want a thin skinned varmint round out of a short barrel? Vmax require a certain velocity to expand. Does a 7 in barrel achieve that? Doubtful.
If you pull your bolt carrier to the rear, with the kns, you can adjust the gas valve through the ejection port. This is only true for the short gas systems.
I must respectfully disagree...I have the Gen 2 Ace Pistol with an EOTech and a KNS adjustable piston and i ABSOLUTELY 100% can adjust the piston without removing the dust cover...BUT i would much rather use the adjuster on the gas block like you guys put together.. I just pull the charging handle ALL THE WAY TO THE REAR and hold it with one hand and adjust the piston with a flat blade screwdriver...I love you guys work and videos and not trying to shit on it....if someone produced that block shown I would recommend it over the KNS though...
Never tried to use a flat head? I’ve always tried to adjust by pulling the handle back and trying to twist the collar with my finger, and It’s a pain.. flat head may be the way to go.
Worth developing? Sure. But the AK optic issue is really easy to solve. Use an AKM side rail and a right side folding stock. I dont like admitting it, but the ruckies made a really good optic rail with very good return to zero repeatability.
Im running the 8.3 with a DeadAir Sandmam and adjustable KNS piston. Very very very rarely have had any sub sonics been through it, but, the Sandman paired with the E-brake mitigates flash from super sonics all day long. Even without the E-brake, I'd get a small burp of flash with the first round from time to time. But, that Dead Air can is an absolute life saver. Super impressed with that can. Even though the KNS piston can be adjusted from the ejection port, it would be awesome to have an adjustable block to make for quick and easy adjustments on the fly. I like the idea of being able to see numbers on a block that i can turn to knowing exactly what each number is dialed for... holding the bolt open and adjusting the piston 3 clicks this way or 2 that way isnt that fun. That being said, i dont see myself in a position where im going from subs to supers while running and gunning... but that option is definitely doable and something I'd like for the "just in case" factor.
I don't know about the Gen 2s, but on my Gen 1 8.3 SBR I can access my KNS piston through the ejection port by pulling the charging handle all the way to the rear. Kinda reminds me of my airsoft days when I had to adjust the hopup on my guns.
I cannot thank you enough for this video. I have been looking at the PSAK-P for a while now, and this gives me a whole lot more to think about than I had been already. You guys really are the best.
I've owned an Arsenal Sam7K with 8.5" barrel for many years. It's lived it's entire life mostly suppressed with a Dead Air Wolverine. It was still flashy with supersonic Russian ammo so I put an Ebrake on it. It now resembles an m4 with bird cage flash hider for flash reference. It served as a stand in 300 BLK for me. Russian brown bear subsonic ammo sounds and runs great with this combo, and I saw no reason to buy 300blk. I've never installed a kns piston in this, and it runs perfectly super Sonic suppressed or not, as well as subsonic. Only need to change the magazine. The milled reciever and metallurgy of all the parts have worn in as well or better than my Russian AK's and Galil Ace gen 2. The Sam7k series guns I rank as among the best in quality for a non custom import gun after my experience with this one example. That said, I bought an mcx in 300blk when the ammo ban happened. 300blk is currently a better suppressor caliber. I could see that changing in the future, but the different loadings are to great and plentiful for x39 to compare currently. Also, an AR style gun is more quiet to my ears than an AK style gun. I enjoy super Sonic shooting from the Sam7k more than my 9" mcx though.
That i must try to find when i start reloading for my 7,62*39 . And .303 bullets one can use also . Finnish use the .308 diameter ,but chamber worked so one can use .311 as usual . Zastava used it also in their rifles so ak and bolts work that way also .
So basically a long stroke piston version of GIGN's 9", 7.62x39 BREN2 (which have the advantage of VERY mild felt recoil even without any accessories and using supersonics, in my experience) Love the good work!
From what I saw on a french channel called Klaim (former Gendarme, but not GIGN) testing the GIGN's BREN 2 SBR, it doesn't seem to have that mild of a felt recoil actually but it seems better still. He mostly complained throughout the video that the buttstock's rough edges and seam between the upper receiver and the folding stock part to be painfull but that can be fixed with a different positioning. At least it can be replaced but they are issued with those and no other modifications in the contract with CZ so there is that. Otherwise it behaves well for 7 meters shots (Mozambique drill and Alpha zone shot placements). Note: the BREN 2 has proprietary mags so it's not even better on the logistical aspect than AK mags. Except for 5.56 versions which are obviously standard but that's not the topic.
@@RonJeremy514 I'll look it up. I shot it after leaving the military and moving to the industry as a R&D design and testing engineer, so I may have more experience than the average gendarme on managing assault rifles recoil (they mostly use HK UMP and sometimes MP5, G36 in some units, and normally have basic training on FAMAS) It was several years ago but I remember being surprised by the weight/recoil ratio. It is about the same size as an MP5 but spits massive fireballs through that vortex flash hider! Felt kind of snappy but absolutely not painful even though I was shooting prone (my HK MR308 can be painful in that position for instance) I got to compare the BREN805 and 5.56 BREN2 with accelerometers and the recoil impulse is just incredibly improved on the newer version, it is quite stunning (and feels so when shooting) I also shot several thousands rounds with preseries BREN2BR 16" (takes standard AR10 pattern mags BTW) and never had an issue with the stock, which I really like - it actually is a good part of the recoil taming part, since shooting the DMR 20" (also a few thousand rounds) with precision aluminium stock was a much less pleasant experience, despite the overall added weight. I actually am impatient for the BR to hit the shelves as it will be my next .308, it is simply that good.
I wish I had bought one of these 8.3" barreled galils when they started importing them, I picked up the 13" instead. Now you can't find the 8" 7.62 guns anywhere
I've had a brain worm idea for something like this. Back when 7.62x39 was cheaper and the platforms didn't cost so damn much. Kinda the Brush Gun POU that hop did a video on a while ago, for hog hunting or heavy bush since the heavier round will carry through privet better.
Reminds me of the mini Draco from resident evil village Swiss Sig makes short barrel 300 blackout and 7.62x39 553s that don’t have the optic problem and already have an externally adjustable gas system
The flash is so bad I choose to not use any kind of flow through can. But even with a 7.62FHFC Sandman S, this thing still throw jets of flame for the first few shots. And you actually don't need to disassemble the short ACE to adjust the KNS piston. The piston is so short, pulling the charging handle all the way back will provide access via the ejection port. 😉
biggest advantage of the 300blk is commonality of parts to a standard AR, it is a very close ballistic twin to the 7.62x39, and can be easily made subsonic. detractors...it can be ACCIDENTALLY loaded into a 5.56 AR chamber and if the round OAL allows it....fired with disastrous results.
There are a few external AK adjustable gas blocks. DA is one, but wouldn't choose for this case. A few russian designs and the occum have the front knob up front like the SG553. There are also a handful of set screw styles like the jmac, which can be adjusted from the front.
Great idea. I’d still rather have a PWS Diablo 7.62x39. Similar size, external gas settings, no zero issues with dust cover optics, and no at home modifications. Duramag 28’s and you are set
While the 300 blackout is slightly more efficient than 7.62x39 in terms of muzzle energy versus grains of powder used in the same barrel length with the same powder and bullets loaded to the same pressures, my 7.62x39 does get slightly higher muzzle velocities. When I step up to slightly slower powders that are better suited for 7.62x39 than 300 blackout, the gap widens. If you shoot enough that ammo cost matters, get a Dillon. Nowadays, the biggest incentive for me to use a blackout or Wilson x39 is the use of small primers and cheaper brass vs 7.62x39. 6 vs half dozen.
10:46 here’s how I set up mine . -Galil tube butt stock - kns adjustable gas piston -jp recoil eliminator (5/8 thread) . That’s had guard is vanilla (no vert grips )
This is an extremely exciting development to see with the Galil. I’d love to see further development on the AK/Galil from you guys. Obviously it’s a similar platform but the fact that no one else seems to have considered that this is a possible solution to either platform is honestly a bit surprising.
@@JNOSNOW The galil or either one? I know people talk about how heavy the AK is but I've never personally thought of them as being particularly heavy. Although I'm willing to admit that the reason for that is because I'm in construction so I'm just carrying and lifting shit overhead all day.
@@Magnus730 the Galil is heavy as shit relative to other guns for it's size. I have the 8.3" and when it's all loaded down it's got to be like 10 pounds. I'm a 5'10" 220 farmer and construction laborer when needed and I have no problem shooting it for a bit but carrying it around all day at a match is just unappealing. I wouldnt want to take it war and have to hike around with it and constantly slug it around. My Zastava M70 is also an amazing gun but it's heavy with thick a receiver. They're great guns, just fucking heavy which gets old after a while. I LOVE shooting my 6.5 # loaded down with can 6.5 Grendel, I can shoot that all day and transition so effortlessly with such little recoil. Everything has a purpose.
@@JNOSNOW I can vibe with that. Different tools, different jobs. That’s all it is. Never handled a Galil personally. But I do have an M70 so not sure what the difference is with our opinions. I don’t personally find it that burdensome when I’m out rucking with it. But then I’ve never owned an AR so maybe I’d feel differently if I trained with one lol
So I got the gen 1. So the optics fix is to move that big ass red dot forward to the fixed rail. Problem one solved. Problem 2 is that it’s a range toy. The gen 2 got all the goodies . So it’s a very loud, and very bright at night range toy. It’s reliable , fun as hell, especially if you can get a drum that fits, and works.
omg omg omg omg omg your finally doing my exact same gun love the thing, after i got the kns adjustable piston anyway. before that thing shot the casings into the stratusphere. :)
woo yeah I love the consequences of trying to decentralize after the corporate-driven centralization/consolidation of the internet and it's subsequent sanitization
From a design and development standpoint I think this is interesting, and honestly, the Ace with the ability to externally dial the gas to the desired performance isn't a bad idea. That said, and here is where I am going to piss someone off. I think the concept at least as presented, in practice, short of some sort of external quick adjust, isn't that useful. Obviously, the adjustment as presented is working prototype, but it would need to be able to quickly, without tools, get adjusted by the shooter, to at least meet the same performance that the 300blk can pull, which is to go from subs, to supers, with a mag change, which is really the selling point of the 300blk over an SMG in my mind. Having the short, and quiet sneaky subsonics, and then with a mag change, being able to push the engagement beyond that nominal 25-50 meters that most people see as the SMG's engagement range and reach out to the 150-200 meters with something with more than pistol performance. That said, I still am not sure where this would realistically be able to make headway when corrosive ammo is brought up into the discussion. As with the AK12 video, there is a definite issue that is possible with leaving the gun uncleaned with with the corrosive ammo out there(And I have to ask if the rust that appears on the rifle in the video is from that), and that ammo, in this scenario, is likely going to be more likely available than not. Now, obviously, remove that issue, and running the gun for several hundred, or even a few thousand rounds between detailed cleanings is really a non issue in my mind. I suppose the question in the end is there a large enough market for this in the Galil.
You can actually adjust the KNS piston by pulling the charging handle back and dialing it through the ejection port. No need to disassemble! I SBRd and suppressed my Gen 1 and that’s how I do it.
everyone is so concerned about losing zero with these but i have not had any issues with mine...or have heard of anyone losing zero... also it's hilarious an ace got bubba'd because 9-hole didn't realize you can adjust the kns pistons in the pistols by pulling the bolt carrier back and exposing the piston - I have never seen anyone make the gas block adjustable on these so that's respect lmfao love the videos tho lol
I'm glad to see someone attempted what I've been eyeballing for a long time, and sad to see the result was the same. I've been looking at 7.62x39 as a cheap way to shoot faux .300 blackout subs without having to pay the absurd subsonic tax, for a long time. But because of Ukraine and the import ban on notRussian 7.62, that dream has been in the grave. The result I came to was that if I wanted a lightweight, controllable, PDW that I could shoot cheaply and quietly, I was looking at having to get a PCC. Because if I went the rifle route of running .300 blackout, I'd be handloading my own subsonics anyway. And with PCC's, its still considerably cheaper for me to make my own funky projectiles that approach the level of God's goofiest soldier of commercial .308 projectiles, than to load straight .300 blk.
As always, the difference is the ammo. 300aac has a better supply chain and uses modern powders. The com bloc ammo out there uses powder so cheap they burn it to start furnaces with it.
12:04 accurate representation of me, handling SVD magazine right after getting used to AK mags (the nose lugs relative to rear lug catch) are much higher up on SVD than AK)
I have a ptr32p that I have similar plans for. Also a fire breather. I can run it suppressed with subsonic or unsuppressed with supersonic. Not either way around.
LOL @ KNS LISTEN UP! They have a brilliant idea. Speaking for everyone, we'll totally buy the heck out of a replacement gas block (and a front sight combo block) and although I hate the idea of clamp on gas blocks, to be commercially viable for the average at home Smith, it's probably gonna hafta be. I just don't know if it can come to market at a price point where it would sell well. Heck, I don't even know how to price my own work in this new economy.
They already have a product that works and is adjustable with a finger tip through the port door. This gas block has to be adjusted with a screw driver so it's actually worse and more expensive.
11:40 how much are you losing zero for every field strip? Manufacturer claims 1MOA shift is expected, but I do suspect it only gets worse with time and wear.
I had a Draco and got rid of it because the muzzle blast while shooting it without any muzzle attachment was worse then shooting my .300 Win Mag with a muzzle brake. So yes Josh, I know how you feel.
As a reloader and if ammo wasn't an issue I wonder. Could you do the same type of Galil Ace but in 9x39mm? Because of the subsonic nature of the ammunition you wouldn't have the concussive muzzle blast when unsuppressed.
Basically, Henry & Josh applied as much lipstick to the pig as possible to get it to sorta approach what a good 300blk weapon can do……but……it can’t switch ammo type without adjusting the gas AND you still have the possible wandering zero due to how optics mount, proving AK type weapons are still pigs. I think AKs are just best left as simple weapons or just entirely ignored.
I am a huge fan of the full sized Ace gen 2 in x39. Sadly, I think that now the MCX SPEAR comes in an 11" x39 varient, that may be the way to go. Which sucks because I HATE x39 AR mags.
I’ve got a really similar setup with a PSA KS47 10.5 SBR with a Sico Omega 300. I haven’t shot it with subsonic 7.62x39 but being a DI gun I don’t see why it wouldn’t work just fine.
I’ve never seen such an aversion to just using 300 blk. MCX tacops and probably the new 6.75” rattler LT are probably the best things for 300 blk and exist.

100% true. I've been doing it wrong this whole time. Thanks.

Yeah you can access it with the bolt pulled to the rear, 100 percent true

He mostly complained throughout the video that the buttstock's rough edges and seam between the upper receiver and the folding stock part to be painfull but that can be fixed with a different positioning. At least it can be replaced but they are issued with those and no other modifications in the contract with CZ so there is that. Otherwise it behaves well for 7 meters shots (Mozambique drill and Alpha zone shot placements). Note: the BREN 2 has proprietary mags so it's not even better on the logistical aspect than AK mags. Except for 5.56 versions which are obviously standard but that's not the topic.
@@RonJeremy514 I'll look it up. I shot it after leaving the military and moving to the industry as a R&D design and testing engineer, so I may have more experience than the average gendarme on managing assault rifles recoil (they mostly use HK UMP and sometimes MP5, G36 in some units, and normally have basic training on FAMAS)
It was several years ago but I remember being surprised by the weight/recoil ratio. It is about the same size as an MP5 but spits massive fireballs through that vortex flash hider! Felt kind of snappy but absolutely not painful even though I was shooting prone (my HK MR308 can be painful in that position for instance)
I got to compare the BREN805 and 5.56 BREN2 with accelerometers and the recoil impulse is just incredibly improved on the newer version, it is quite stunning (and feels so when shooting)
I also shot several thousands rounds with preseries BREN2BR 16" (takes standard AR10 pattern mags BTW) and never had an issue with the stock, which I really like - it actually is a good part of the recoil taming part, since shooting the DMR 20" (also a few thousand rounds) with precision aluminium stock was a much less pleasant experience, despite the overall added weight. I actually am impatient for the BR to hit the shelves as it will be my next .308, it is simply that good.
I own AK47, IWI Galil Ace, Cz Bren 2 and CMMG mk47, the Bren is not as good as the Galil, nope
I wish I had bought one of these 8.3" barreled galils when they started importing them, I picked up the 13" instead. Now you can't find the 8" 7.62 guns anywhere
I've had a brain worm idea for something like this. Back when 7.62x39 was cheaper and the platforms didn't cost so damn much.
Kinda the Brush Gun POU that hop did a video on a while ago, for hog hunting or heavy bush since the heavier round will carry through privet better.
Reminds me of the mini Draco from resident evil village
Swiss Sig makes short barrel 300 blackout and 7.62x39 553s that don’t have the optic problem and already have an externally adjustable gas system
The flash is so bad I choose to not use any kind of flow through can. But even with a 7.62FHFC Sandman S, this thing still throw jets of flame for the first few shots.
And you actually don't need to disassemble the short ACE to adjust the KNS piston. The piston is so short, pulling the charging handle all the way back will provide access via the ejection port. 😉
your expression on the post credit scene is EXACTLY what i did as soon as i got this thing. Its a hoot to shoot. the fireball is insane LOL
I just found the a new channel to binge watch!!!
Ammo development goes a long way for .300bo. I know 7.62x39 but it’s like there is a round for everything for .300.
biggest advantage of the 300blk is commonality of parts to a standard AR,
it is a very close ballistic twin to the 7.62x39, and can be easily made subsonic.
detractors...it can be ACCIDENTALLY loaded into a 5.56 AR chamber and if the round OAL allows it....fired with disastrous results.
I kind of did the same thing. Bought a bren 2 in x39 to compliment my 300blk AR. Think I would choose the bren over the AR.
It really grinds my gears that RUclips would block such informative and gentlemanly educational content
This is an 80's action movie level of coolness
The mag change at 1:17 is just... chef's kiss.
Also 1:50
There are a few external AK adjustable gas blocks. DA is one, but wouldn't choose for this case. A few russian designs and the occum have the front knob up front like the SG553. There are also a handful of set screw styles like the jmac, which can be adjusted from the front.
I’ve found my 10 inch 300 blk to be the perfect length for supers and subs. Excellent pdw
In the description, add the parts /scope/ect used, gives us some idea what works and what doesn’t
Great idea. I’d still rather have a PWS Diablo 7.62x39. Similar size, external gas settings, no zero issues with dust cover optics, and no at home modifications. Duramag 28’s and you are set
That's a completely better gun. I have both (mk111 7.62) and the PWS is absolutely better in just about everyway
7.62 Ars lmao. What a meme
A meme lol? You must have no experience with PWS, that's the only thing I can think of.
@@JNOSNOW it's a puny bolt. They break prematurely. You only have 90 rounds in your gun, but any teal round count will crack the bolt fairly easily.
@@rustys.1070 you clearly have no idea what you're talking about.
1:32 the universal face of "fucking concussion"
They were cookin with that intro
I like the french interlude.
While the 300 blackout is slightly more efficient than 7.62x39 in terms of muzzle energy versus grains of powder used in the same barrel length with the same powder and bullets loaded to the same pressures, my 7.62x39 does get slightly higher muzzle velocities. When I step up to slightly slower powders that are better suited for 7.62x39 than 300 blackout, the gap widens.
If you shoot enough that ammo cost matters, get a Dillon. Nowadays, the biggest incentive for me to use a blackout or Wilson x39 is the use of small primers and cheaper brass vs 7.62x39. 6 vs half dozen.
Very cool, great video
That clip right at the end says it all. Fireballs and laughter
10:46 here’s how I set up mine .
-Galil tube butt stock
- kns adjustable gas piston
-jp recoil eliminator (5/8 thread) .
That’s had guard is vanilla (no vert grips )
one of the best channels on youtube quality entertainment and punches above the rest
Frenchman! I never thought he could pull that out of the arsenal. 😂
This is an extremely exciting development to see with the Galil. I’d love to see further development on the AK/Galil from you guys. Obviously it’s a similar platform but the fact that no one else seems to have considered that this is a possible solution to either platform is honestly a bit surprising.
The biggest downside is it's heavy as shit for such a little gun. Absurdly heavy.
@@JNOSNOW The galil or either one? I know people talk about how heavy the AK is but I've never personally thought of them as being particularly heavy. Although I'm willing to admit that the reason for that is because I'm in construction so I'm just carrying and lifting shit overhead all day.
@@Magnus730 the Galil is heavy as shit relative to other guns for it's size. I have the 8.3" and when it's all loaded down it's got to be like 10 pounds. I'm a 5'10" 220 farmer and construction laborer when needed and I have no problem shooting it for a bit but carrying it around all day at a match is just unappealing. I wouldnt want to take it war and have to hike around with it and constantly slug it around. My Zastava M70 is also an amazing gun but it's heavy with thick a receiver. They're great guns, just fucking heavy which gets old after a while. I LOVE shooting my 6.5 # loaded down with can 6.5 Grendel, I can shoot that all day and transition so effortlessly with such little recoil. Everything has a purpose.
@@JNOSNOW I can vibe with that. Different tools, different jobs. That’s all it is. Never handled a Galil personally. But I do have an M70 so not sure what the difference is with our opinions. I don’t personally find it that burdensome when I’m out rucking with it. But then I’ve never owned an AR so maybe I’d feel differently if I trained with one lol
So I got the gen 1. So the optics fix is to move that big ass red dot forward to the fixed rail. Problem one solved. Problem 2 is that it’s a range toy. The gen 2 got all the goodies . So it’s a very loud, and very bright at night range toy. It’s reliable , fun as hell, especially if you can get a drum that fits, and works.
I have the Galil ace in 5.45 with the 8 inch barrel. Its like my own modern day krink. If only i could get the ammo
For the next “tasting” bit Henry should get a idf helmet cover and be a chef inviting to taste all the entrees on the menu
You guys need to run this at Kalashbash in April!
omg omg omg omg omg
your finally doing my exact same gun
love the thing, after i got the kns adjustable piston anyway. before that thing shot the casings into the stratusphere. :)
Man i miss when the internet was actually good and not 50 fucking subscription services
woo yeah I love the consequences of trying to decentralize after the corporate-driven centralization/consolidation of the internet and it's subsequent sanitization
Same
@@Reshiram9001Right ? I cant believe they shut down omegal! How else I’m a goanna conduct nefarious activities?!
It's loaded up for you to view without a subscription, man...we just can't post it on youtube because of their rules....sorry
Yes I believe it’s a good idea, worth full development.
AK platform is slept on.
Bro we have damn near the EXACT gun and setup minus the stock. Suppressor and all, my favorite gun.
The VZ58 with the 7.5 inch barrel makes a better 7.62x39 PDW. It's smaller, thinner and lighter.
eyyyyyy ive been waiting for this since that sneak peak a while back. and now you show a valmet
From a design and development standpoint I think this is interesting, and honestly, the Ace with the ability to externally dial the gas to the desired performance isn't a bad idea.
That said, and here is where I am going to piss someone off. I think the concept at least as presented, in practice, short of some sort of external quick adjust, isn't that useful. Obviously, the adjustment as presented is working prototype, but it would need to be able to quickly, without tools, get adjusted by the shooter, to at least meet the same performance that the 300blk can pull, which is to go from subs, to supers, with a mag change, which is really the selling point of the 300blk over an SMG in my mind. Having the short, and quiet sneaky subsonics, and then with a mag change, being able to push the engagement beyond that nominal 25-50 meters that most people see as the SMG's engagement range and reach out to the 150-200 meters with something with more than pistol performance.
That said, I still am not sure where this would realistically be able to make headway when corrosive ammo is brought up into the discussion. As with the AK12 video, there is a definite issue that is possible with leaving the gun uncleaned with with the corrosive ammo out there(And I have to ask if the rust that appears on the rifle in the video is from that), and that ammo, in this scenario, is likely going to be more likely available than not. Now, obviously, remove that issue, and running the gun for several hundred, or even a few thousand rounds between detailed cleanings is really a non issue in my mind.
I suppose the question in the end is there a large enough market for this in the Galil.
This is great! Can't wait for the Halo 2 smg review!
0:15 😐 Damm, i forgot my lighter at home.
😎 no problem, bro. i got you covered.
Great video! Very interesting. Thank you 👍🏻
You can actually adjust the KNS piston by pulling the charging handle back and dialing it through the ejection port. No need to disassemble! I SBRd and suppressed my Gen 1 and that’s how I do it.
You must have some skinny fingers? Not trying to be funny but it’s a pain trying to wedge my finger in and accurately adjust the position
@@Grip3 screwdriver?
It seems to be an answer in search of a question.
Did you watch the video
This is so stupid and impractical when theres so many good 300blk options...
I need it.
This is 1/3 the cost for the same performance
Awesome muzzle flash.
everyone is so concerned about losing zero with these but i have not had any issues with mine...or have heard of anyone losing zero...
also it's hilarious an ace got bubba'd because 9-hole didn't realize you can adjust the kns pistons in the pistols by pulling the bolt carrier back and exposing the piston - I have never seen anyone make the gas block adjustable on these so that's respect lmfao
love the videos tho lol
You must have some skinny fingers? Not trying to be funny but it’s a pain trying to wedge my finger in and accurately adjust the position
@@Grip3 i don't own the pistol, i just know you can do it
Hornady sells 7.62x39 255 gr Sub-X subsonic rounds now.
I feel like we never get enough Galils in the civilian market, but especially the Galil ACE
I want an alpha galil ace. That stock with free floating rail and hinged top cover would be nice especially with an adjustable gas block.
If I remember correctly, Ian at Forgotten Weapons mentioned that the GIGN uses BREN2 7.62x39 for suppressed use.
The 1301 has replaced all semi auto shotguns in my collection.
It is only complimented by an older Beretta A300 for birds.
I'm glad to see someone attempted what I've been eyeballing for a long time, and sad to see the result was the same. I've been looking at 7.62x39 as a cheap way to shoot faux .300 blackout subs without having to pay the absurd subsonic tax, for a long time. But because of Ukraine and the import ban on notRussian 7.62, that dream has been in the grave.
The result I came to was that if I wanted a lightweight, controllable, PDW that I could shoot cheaply and quietly, I was looking at having to get a PCC. Because if I went the rifle route of running .300 blackout, I'd be handloading my own subsonics anyway. And with PCC's, its still considerably cheaper for me to make my own funky projectiles that approach the level of God's goofiest soldier of commercial .308 projectiles, than to load straight .300 blk.
If you already have the 5.56 brass, 300BLK is cheaper than .308 to handload if you’re just comparing FMJ.
Would maybe need a tighter twist rate barrel to work really well , also in .311 size bore , so it can use std AK ammo .
As always, the difference is the ammo. 300aac has a better supply chain and uses modern powders. The com bloc ammo out there uses powder so cheap they burn it to start furnaces with it.
Definition of lighting your path in an AK format
12:04 accurate representation of me, handling SVD magazine right after getting used to AK mags (the nose lugs relative to rear lug catch) are much higher up on SVD than AK)
I have a ptr32p that I have similar plans for. Also a fire breather. I can run it suppressed with subsonic or unsuppressed with supersonic. Not either way around.
Good stuff, Guys!
Sweet a Galil Ace getting it's love
LOL @ KNS LISTEN UP!
They have a brilliant idea. Speaking for everyone, we'll totally buy the heck out of a replacement gas block (and a front sight combo block) and although I hate the idea of clamp on gas blocks, to be commercially viable for the average at home Smith, it's probably gonna hafta be. I just don't know if it can come to market at a price point where it would sell well. Heck, I don't even know how to price my own work in this new economy.
They already have a product that works and is adjustable with a finger tip through the port door. This gas block has to be adjusted with a screw driver so it's actually worse and more expensive.
Doesn’t rifle dynamics offer an adjustable gas block, circumventing the KNS being needed?
Josh and Henry, you guy's should do a vid on the PSA JAKL or if you wanna go a little more pricey, the IWI Carmel
Amazing content
This is an awesome project nice work! Try the Bren 2 7.62x39 of same size! I can loan y’all mine if ya like
Have this exact setup myself. Only differences are I'm running an eotech and a Zenitco foregrip and a Gen 1.
Wouldn't the Bren 2 in 7.62x39 with a 9 inch barrel be a good choice as well?
11:40 how much are you losing zero for every field strip? Manufacturer claims 1MOA shift is expected, but I do suspect it only gets worse with time and wear.
Fireball :D
Cool package.
The screw driver is the secret ingredient in any weapons arsenal
itll be cool to see them review the new sureshot chassis for the aks74u
I had a Draco and got rid of it because the muzzle blast while shooting it without any muzzle attachment was worse then shooting my .300 Win Mag with a muzzle brake. So yes Josh, I know how you feel.
As a reloader and if ammo wasn't an issue I wonder. Could you do the same type of Galil Ace but in 9x39mm? Because of the subsonic nature of the ammunition you wouldn't have the concussive muzzle blast when unsuppressed.
With that barrel shroud and foregrip my mind keeps thinking it's a G36c.
Is your Galil Ace Gen2 PDW also able to fire 0.5-1” out of battery? Mine has been benched since I discovered that.
What? People lie on the internet like no one else will know what hes talking about
What?@@rustys.1070
This is some incredible content. Great job.
Basically, Henry & Josh applied as much lipstick to the pig as possible to get it to sorta approach what a good 300blk weapon can do……but……it can’t switch ammo type without adjusting the gas AND you still have the possible wandering zero due to how optics mount, proving AK type weapons are still pigs. I think AKs are just best left as simple weapons or just entirely ignored.
I am a huge fan of the full sized Ace gen 2 in x39. Sadly, I think that now the MCX SPEAR comes in an 11" x39 varient, that may be the way to go. Which sucks because I HATE x39 AR mags.
I’ve got a really similar setup with a PSA KS47 10.5 SBR with a Sico Omega 300. I haven’t shot it with subsonic 7.62x39 but being a DI gun I don’t see why it wouldn’t work just fine.
It’s also not nearly as heavy as the Galil Ace and it works.
I’ve never seen such an aversion to just using 300 blk. MCX tacops and probably the new 6.75” rattler LT are probably the best things for 300 blk and exist.
Try watching the video and actually listening next time
Sweet video.
I think the 300 is better in the US. The recent cost of x39 kinda ruins these cool platforms.
Did you crudely watch the video? It's designed for the middle east not the US
