Dude! I am an engineer. I loved your rant about gas issues and cold! You went into a deep dive into the insanity of the AR. There is an alternate way to reduce the gas, a gas tube with a smaller hole. The nice thing about the AR platform is the lack of training needed to be a gunsmith. There is one issue with the AR, that is the frustration finding parts that will work for your build.
I really want to try one of these builds... Might get around to it sometime, the Riflespeed block is definitely a cool product. Thanks again for the content!
@@Rebellion1776 just got it tuned and sighted in nicely! The 2nd shortest knob fits perfectly with the 10.5 midwest slim handgaurd and have it set to 7 with the stock plunger to cycle anything reliably. Everyone thats seen it is impressed by the hella flushment
@Dahm45 yeah I think this is the solution for 12.5" gas problem. Seems to have worked really well for yours, so that will probably be the road I head down too.
I made a 16in rifle gas build similar to yours with a KAK Industry barrel, lo pro standard gas block, and a A2 stock with standard rifle buffer parts and haven't had any issues with it cycling with or without a suppressor with 5.56 ammo. No gas to the face and it runs stupid smooth. I have a LaRue MBT2S trigger in it and its very nice to shoot.

This is why you make sure to always coat the set screw in high temperature anti seize and you periodically run the screw forwards and backwards to clear out any carbon
@@kilroy5166 Easier said than done. Not everyone wants a pricey Riflespeed that weighs 4x a standard gas block. The detent based ones like Superlative arms work really well, and as he said, are generally a set and forget, but yeah, periodically using the screw to ensure it doesn’t get locked up is good practice.
You mentioned several times that this video is getting long and you are rambling, but I came across your channel while researching the SFAR, and the very fact that you get into the little details like why you chose the handguard you used and all the details about the riflespeed gas block etc is why I now subscribed to your channel. I am a huge detail guy, and am obsessive about getting stuff to work right and look right. Every question I had about the sfar and the riflespeed gas block have been answered, and a lot of unexpected great info about handguards was also included. Thanks much Bro!
I have a 11.5" midlength faxon which is definitely in the dissipator category. I use fixed gas on it because like hop i dont like adj gas blocks. While I am sure it recoils more than a tuned gun would, with an H3 and sprinco red it still has considerably less recoil than my 10.5" carbine gas gun, and it will still work with cheap .223 reman loads. In fact it has never failed to function in any way, in temps from about 0f well into the high 90s. Also, hello Hop.
I got the same kak barrel and went with a centurion two peace quad rail handguard. Now my other 16" rifle length gas barrel I got an FN 18" had my gunsmith open up the gas port, cut and thread the barrel to 16" and attached the rest of the hardware to include triangle handguard. I used the H&R upper and lower receivers from PSA. It's my favorite AR to use for pretty much everything now.
I went with a rifle speed system based off your video. Awesome gas block. Went on my 308 noveske 16” barrel with a 14.5 zev handguard. Runs flawlessly.
Ya, the Riflespeed gas block is pretty sweet, but getting a hand guard to work can be a real struggle. It sits taller the normal low pro blocks, so not all handguards will slip over it. And if it does, make sure there is enough room that the barrel stays free floating during firing.
I built a 16" rifle gas competition gun with a Criterion Hybrid barrel and I've been super happy with the results. I'm running an empty buffer and a Geissele Super 42 spring with a AIM lightweight bolt. I'm not even sure the Riflespeed was even a thing a couple of years go when I built the gun so I used the SLR and setup the gun to run on a fairly hot .223 load when dirty.
Love the vid, I enjoy these build type videos. I am currently working on a 20” AR-RPK upper that has been in my mind for two years now. Going to use this this gas block, with a DD mlok handguard, and a 20” criterion HBAR. I want it to be accurate and absorb heat well. No joke about their barrels never being in stock, mine is on back order.
Have a midwest industries quad on my 16”’carbine. Love it, stiff not to heavy and no screwing with adapters and crap contacting my barrel and such. Just stick it on and done. They dehorn/deburr it too so unlike the KAC quad I had in Iraq, it doesn’t chew up your clothes and hands.
Solid build. FocusTripp put together a "dissipator" a while back with interesting results, dude does some great work! "Stay Strong, Chase Excellence Brothers." - Godspeed
I AM an engineer and didn’t get pissed 😂. For someone who’s not an engineer, ya definitely explain things in enough easy enough to follow detail that you should definitely be one in this industry broham 🤙🤙
Man this is giving me some really great ideas. This honestly seems like a really great style of build especially for shorties. Like, shorties with carbine length systems are what they are. They aren't horrible, but definitely not what you really want these days given what we and the military now know about what the most reliable and functional gas lengths are.
Great video! I love my RS block. Put it on my AR-10 and AR15 ... both suppressed. Was difficult to figure out which plunger was better for the 15 but after using the second plunger provided in the box... runs clean. 3pm ejection pattern.
So glad you got one of these. Been running one on a suppressed 300 BLK for awhile and it’s just fun. Only issue I’ve had is freezing up the plunger due to the pistol length gas system. Lubing it up once a while takes care of that issue. From 300 supers to subs to with or without suppressor it fits my build perfectly.
Should be noted I have a larger gas port drilled out so that’s where some more issues come from but allows me to get that full range. Works for me 🤷🏻♀️
I have 2 uppers I've installed the Riflespeed adjustable gas block. Absolutely awesome toolless adjustable system. The last thing you want to do is rummage around for an Allen wrench or even a shell case to adjust your gas. Just grab the numbered sleeve and click it up or down a click to tweak your setting. And perfect ejection pattern.
I've had one of these on a shorty .300 blk I built for a bit over a year at this point. I was really impressed, my goal was to make a super light gun that works reliably both suppressed and unsupressed, I was very close to accomplishing this. With super sonic .300blk it works great both suppressed and unsuppressed, with subsonics though it has occasional hickups when unsupressed.
Do you really need to cycle subs unsuppressed though? The entire point of subs is shooting suppressed. With 300 BLK, I'd rather have a short barrel with pistol length gas system with a non-gaped gas port that can cycle subs suppressed but also isn't terribly over-gassed when shooting supers suppressed, with a standard gas block.
@@AncientGloom nope, I sure don't and that's why I'm not too worried that it has occasional hickups shooting subs unsupressed. I really just used that as a measure of reliability with varying .300 blk loads aince even with supersonic .300 blk there are guns that are picky with ammo unsupressed. It's also really very pleasant to shoot even with supers supressed at least in comparison to something like a mk18.
I should probably just watch more of your videos for the answer but, I’ve got an iwi Zion 15 tac 12. It is a 12.5” 5.56 with midlength gas system. It comes stock with carbine coil and 4oz buffer. With just pmc xtac 55g m193 ammo….its quite strongly gassed. So much so in fact, that I’ve already added a red/white, springco cryo treated and an rb5000 kynshot…and it now shoots very nicely. I’ve ordered the tubbs 36 coil flatty, waiting for it to arrive to try out as my ocl polonium (full size, full bp!). I’ve also got an SA agb. I’m waiting for the can to be approved before I install the 6315rf and SA block….as I have another 16” complete upper, with a 3P15, and an Ecco machine adapter for the polo. My question is for the 16” gas block (also midlength gas)…is the Riflespeed system worth the $199? When I can get the SA block for $79? Or even a wojtek for $65? The riflespeed would look really cool. But $120++ for an agb should be remarkable.
Adjusting the SA is pretty annoying and adjusting the Wojtek is even worse. So it depends on how much tuning you want to do and if you want to shoot both with and without the suppressor.
I've been trying to suppress my LWRCI DI 16.1" for awhile now. Rifle came VERY over gassed out of the box, ejection was right at 1:30. Geissele braided spring and h3 buffer magically took a 1:30 ejection and made it right at 4 o'clock but felt recoil was definitely increased which was very strange. Reliability still at 100% after testing 300 xm193 and 50 BH 77G OTM..... Throw a suppressor on and becomes a jam-o-matic....
I like the SL MI handguard so this is a bonus. Very interesting review of a Dissy and this Riflespeed GB. Wish you would have shown how it was attached to barrel. Set screws, pinned, cross bolts??
After Focustripps video I became motivated to make this myself. I havent started putting the list together but I know for sure what its gonna be "called" Mk12 Mod D. The PRI tubes come in 14" and I think that would be a sick rifle concept
I had to use one of the BRT gas tubes on a 16" faxon gunner barrel and it worked well, for how long, we'll see.. i live that barrel accept for the oversized gas port.
You can grind a bit off the QD's and theyll still function. Just dont go into the bearings. Itll clear the front block. I have a SFAR and an integral 300blk i had to do it to.
I stopped using the Bootleg carrier because the gas adjustments were too extreme. On most of my builds the first click would stop function completely because they weren't overgassed enough to make use of it.
That's a set-and-forget type system, which I'm mostly uninterested in. The ability to adjust on the fly is the only reason you wouldn't just choose a different barrel/gas tube/buffer system to tune permanently instead.
I've got the standard collar Riflespeed gas block on a Roscoe K9 11.5'' barrel with patrol gas length and a BCM MCMR10 and I can report that it is hella flush (with the help of a belt sander).
I made my own 12.5 mid gas barrel by cutting down a PSA freedom 16 inch barrel. Sizing the gas port was the most tedious part. It is an absolute joy to shoot.
The riflespeed gas block makes the AR essentially a infinitely adjustable system like the FAL. I loved the one I had on a 300 BO 7" upper. A simple twist to go from supers/subs/suppressed/unsuppressed...sorry for the boating accident.
I keep thinking I want a KAK dissipator barrel but haven't capitalized on it yet. I want an A2 front sight gas block. Would be super sweet if it was adjustable. Great video as always
I'm Running a POF Adjustable Gas Block on A 18" 1 in 12" twist Barrel, and it Also Had The Problem of Being WAY Over Gassed ( along with the JP Silent Buffer / Recoil System ) @ first I Was Running The Standard Gas System And It Felt Like The Rifle Was Going to Brake in Half. Now It's As Smooth as Can Be. I'm Still Sorry about hearing You're James's brother.
I have a 16" Criterion hybrid rifle gas barrel with a fixed block and a brt tube. Running an A5H3, thing is incredible suppressed. I have to go down to an A5H0 unsuppressed, but it still cycles fine dirty and in shitty weather.
I only watch these to see the fur baby. Also working on a pencil barrel 20 in light weight build and would like to have a qd can set up so thinking about this adjustable gas block but the 17in rail makes it a stretch to access with an Allen key. Would love to see it with that longer quick adjust clicker. *air biscuits paws*
3:15 Why charging handle... WHY?? 6:10 BOOM! IN DA FACE!!! 19:47 Murder Mittens! **I'm not going to touch the 'if you are cold, they are cold' Revisit that with condensation in mind**
I used to build uppers for an armory with the aero (ba) pencil barrels pistol lengths, Usually 10.5 with carbine length gas systems, they all ran really well. I used one w the t2 buffer and it was still pretty punchy plenty of gas. Unintentional dissipation lol.
I went with BRT Tubed gas tube . I've never been a fan of Adj Gas blocks . Rifle Speed does look interesting. I only shoot 1 type of ammo thru most of my rigs . Which makes it easier to dial in . BRT 0.073 Tuned Gas Tube is what works best for me on my 3 13.X" Middys .
I just picked up a compass lake engineering 12.5 mid barrel, believe it’s a .750 gas port. Had to dump all the weights out of a carbine buffer to get it to run at the range.
I don’t know if this helps you or not but on one of my rifles I filed down the length of the screws so I could use an M lock slot close to my gas block to mount a bipod.
I literally just randomly picked the anderson A4 dissipator video... and then saw this drop! I went to look for the upgrades videos and this dropped! Its like you read my mind through the internet. I tried to think of how... nearest I can tell the 5G waves were reading my thoughts that were amplified by the antenna created between my skull and the the toilet bowl. The pushing energy and yelling sent this message back in time to give you the idea for the video! This means there should be an A-Team and Baywatch reboot any minute! Woot!
16:28 grind down the QD. it really only needs 1/16" past the bearings looks like you have the ferro concepts QDs. I filed mine down to 1/8 pas bearings. Held for 4years and counting.
my only gripe with the rifle speed gas block other then price, is the weight. The shortest one is nearly 4 oz and get heavier as you go longer. Added to the fact that they get installed at the far end of the rifle only makes the additional weight feel worse. I like to strip any unnecessary weight from my builds and use an adjustable gas block to make sure the BCG still cycles properly. I would love one of these but only if they made them lightweight. Maybe aluminum or titanium for the body and steel where it really matters. If they can cut the weight to one or two Oz. I'd buy several
Im in the process of building a 16" upper that'll primarily be suppressed. It has an intermediate gas system. Im going run the RS7533 gas block with a 13.5" hand guard. Hopefully it works out nice.
I can picture a set of Aero receivers with the built in rail interface working out well for a build like this, plenty of room under there and I think they make a 13 something, have to look now. BTW after seeing how this worked on your 308 build I'm going to give one a try on a large frame frakengun I'm working on.
This is long and i'm sorry, but i'm trying to help add to the hive mind of information about this type of build because i really enjoy it lol. I have one of those barrels, although its not in a build yet. Even though its a dissipator barrel, its gas port is much larger than I think it needs to be at .121. 20" rifle barrels are usually like .098 in the TDP I think. Of course, the TDP doesn't account for crappy commercial ammo, crappy commercial grade parts, or that its shorter dwell time. So naturally, a increase in size should be added to the port when considering the variables we need to overcome, like you rightly mentioned (or eliminate some of those variables). But I would argue that margin isn't 23 thousandths, rather its more like 5 to 10, which is still a bigger swing than you'd think. Its the same issue Focus Tripp described on your 12.5 mid from KAK. They apparently don't' care enough to perform testing to find out what's an appropriate size OR they are fighting leaky / inefficient gas systems and aren't aware of it. Could that be why the K-Spec exists? To vent gas elsewhere from their ridiculous gas ports? Ejection pattern is not gospel, but i am using it here get a ballpark idea. The 16" rifle gas AGP barrel from "Special Ops Tactical" (the trifecta of cringe company names) has a smaller gas port than that of the KAK (im pretty sure). I can't remember the exact size, I need to go re-check it cause I can't find it in my notes. But I run it with a standard BCG (gauged efficient), non adjustable block, A5H2 (w/standard spring) and a turbo t2. Off the shoulder test held in my hands only. Gun is new but around 500 hundred rounds fouled and on the cusp of needing more lube (i use grease). Upper is milspec forged, so the brass deflector is the standard profile. Rainy and mildly cold weather. One round at a time, all rounds locked back on a empty mag - Unsuppressed: despite the A5H2 (effectively an h3), the gun ejects at 3 o clock sharp with Tula and ejects around 2 with Federal XM193. / Suppressed (turbo t2): ejects at 1 with XM193 and around 1:30/2 with Tula. The unsuppressed behavior with a smaller gas port than the KAK barrel is whats most interesting to me. lt leads me to believe the KAK is way over-sized beyond a safety margin for conditions and ammo variables. Your Anderson's behavior was obviously different which is also interesting. I theorize a difference in ammo and gas system efficiency to be the difference there most likely. But i would go as far to say if you sealed the gas tube at the FSB with loctite 620 and got a carrier that was efficient (gas key doesn't leak + gas key is proper size + bolt tail seal proper size + gas tube proper size), it would probably run completely different; and i'd be willing to bet that at least 2 of those variables are inefficient on the Anderson. A sealed up efficient gas system makes more of a difference than people think in running crap ammo in bad conditions. Rather than taking up the slack for crap parts by hogged out gas ports, I wish manufacturers would just learn how to build and qc gas efficient parts. BCM apparently gauges their BCG's with air volume to check efficiency. Supposedly no other manufacturer does that.

I should probably just watch more of your videos for the answer but, I’ve got an iwi Zion 15 tac 12. It is a 12.5” 5.56 with midlength gas system. It comes stock with carbine coil and 4oz buffer. With just pmc xtac 55g m193 ammo….its quite strongly gassed. So much so in fact, that I’ve already added a red/white, springco cryo treated and an rb5000 kynshot…and it now shoots very nicely. I’ve ordered the tubbs 36 coil flatty, waiting for it to arrive to try out as my ocl polonium (full size, full bp!). I’ve also got an SA agb. I’m waiting for the can to be approved before I install the 6315rf and SA block….as I have another 16” complete upper, with a 3P15, and an Ecco machine adapter for the polo. My question is for the 16” gas block (also midlength gas)…is the Riflespeed system worth the $199? When I can get the SA block for $79? Or even a wojtek for $65? The riflespeed would look really cool. But $120++ for an agb should be remarkable.
Adjusting the SA is pretty annoying and adjusting the Wojtek is even worse. So it depends on how much tuning you want to do and if you want to shoot both with and without the suppressor.
Fantastic video!!! Haven't seen much on the Tube of Yous about the AR10 version of the Rifle Speed system.
Been wanting to try out one of these. A new dissy build seems like a great way to put it to use.
Definitely the best reviews on Dissapator and 16" with rifle length gas. Hoping to see a long term/round count update on this rifle.
I've been trying to suppress my LWRCI DI 16.1" for awhile now. Rifle came VERY over gassed out of the box, ejection was right at 1:30. Geissele braided spring and h3 buffer magically took a 1:30 ejection and made it right at 4 o'clock but felt recoil was definitely increased which was very strange. Reliability still at 100% after testing 300 xm193 and 50 BH 77G OTM..... Throw a suppressor on and becomes a jam-o-matic....
Too tired to even threaten me with violence huh? I felt that one. 😂😂😂
Honestly I don't mind a longer vid. You put out good stuff man
I haven't figured it out yet, what mags are you using? I'm starting to think you kitbashed them yourself from different bodies and floorplates.
That zero recoil setup is hilarious. Id get into competition shooting just to justify a build like that with an aluminum bcg lol.
I like the SL MI handguard so this is a bonus. Very interesting review of a Dissy and this Riflespeed GB. Wish you would have shown how it was attached to barrel. Set screws, pinned, cross bolts??
Set screws, dimpled barrel. You can cross pin them but I have never bothered with the RS.
Oh damn, was wondering who was doing that when I saw it on insta. Awesome to see this. Thinking I am throwing the hux on my 12.5 mid.
Dissipater barrels are cool looking. I got a faux upper from PSA. I don’t want to mess with reliability.
Looking good.
After Focustripps video I became motivated to make this myself. I havent started putting the list together but I know for sure what its gonna be "called" Mk12 Mod D. The PRI tubes come in 14" and I think that would be a sick rifle concept
I had to use one of the BRT gas tubes on a 16" faxon gunner barrel and it worked well, for how long, we'll see.. i live that barrel accept for the oversized gas port.
You can grind a bit off the QD's and theyll still function. Just dont go into the bearings. Itll clear the front block. I have a SFAR and an integral 300blk i had to do it to.
What is better to have the adjustable gas block or an adjustable BCG? Comparison maybe?
I stopped using the Bootleg carrier because the gas adjustments were too extreme. On most of my builds the first click would stop function completely because they weren't overgassed enough to make use of it.
@@Hoplopfheil what about the SAGRS BCG?That one seems to have a screw in the gas key instead of side adjustments.
That's a set-and-forget type system, which I'm mostly uninterested in. The ability to adjust on the fly is the only reason you wouldn't just choose a different barrel/gas tube/buffer system to tune permanently instead.
The best explanation on dwell time and the Rifle Speed adj gas block.. Finally, someone got it right..
I've got the standard collar Riflespeed gas block on a Roscoe K9 11.5'' barrel with patrol gas length and a BCM MCMR10 and I can report that it is hella flush (with the help of a belt sander).
I got same barrel but no rail yet. Could you get away with a 10.5 rail? I'd like to see a picture
Another great review Hop.
Great to see another Hop video so quickly. FYI for any SCAR owners, the Scarburetor is a similar setup for that platform. @eduardo moniet
I made my own 12.5 mid gas barrel by cutting down a PSA freedom 16 inch barrel. Sizing the gas port was the most tedious part. It is an absolute joy to shoot.
The riflespeed gas block makes the AR essentially a infinitely adjustable system like the FAL. I loved the one I had on a 300 BO 7" upper. A simple twist to go from supers/subs/suppressed/unsuppressed...sorry for the boating accident.
I keep thinking I want a KAK dissipator barrel but haven't capitalized on it yet. I want an A2 front sight gas block. Would be super sweet if it was adjustable. Great video as always
I have a Delton Dissy upper with(non-adjustable) rifle length gas. They redid the gas ports at the factory, and I've never had an issue with it.
@@Allenmar73Nope, I slapped it onto a KE Arms lower and its worked 100%
I'm Running a POF Adjustable Gas Block on A 18" 1 in 12" twist Barrel, and it Also Had The Problem of Being WAY Over Gassed ( along with the JP Silent Buffer / Recoil System ) @ first I Was Running The Standard Gas System And It Felt Like The Rifle Was Going to Brake in Half. Now It's As Smooth as Can Be.
I'm Still Sorry about hearing You're James's brother.
I have a 16" Criterion hybrid rifle gas barrel with a fixed block and a brt tube. Running an A5H3, thing is incredible suppressed. I have to go down to an A5H0 unsuppressed, but it still cycles fine dirty and in shitty weather.
I only watch these to see the fur baby. Also working on a pencil barrel 20 in light weight build and would like to have a qd can set up so thinking about this adjustable gas block but the 17in rail makes it a stretch to access with an Allen key. Would love to see it with that longer quick adjust clicker. *air biscuits paws*
3:15 Why charging handle... WHY??
6:10 BOOM! IN DA FACE!!!
19:47 Murder Mittens!
**I'm not going to touch the 'if you are cold, they are cold' Revisit that with condensation in mind**
More like 6:07
I agree the cold isn't so much the problem. Its the large swing in ambient temp.
Spinta Precision also makes (made?) a 16" Rifle gas barrel. Or at least did years ago when I built my dissy.
This a sick setup. Great content!
I used to build uppers for an armory with the aero (ba) pencil barrels pistol lengths, Usually 10.5 with carbine length gas systems, they all ran really well. I used one w the t2 buffer and it was still pretty punchy plenty of gas. Unintentional dissipation lol.
I went with BRT Tubed gas tube . I've never been a fan of Adj Gas blocks . Rifle Speed does look interesting.
I only shoot 1 type of ammo thru most of my rigs . Which makes it easier to dial in . BRT 0.073 Tuned Gas Tube is what works best for me on my 3 13.X" Middys .
I just picked up a compass lake engineering 12.5 mid barrel, believe it’s a .750 gas port. Had to dump all the weights out of a carbine buffer to get it to run at the range.
Any commentary on effects / settings for “flow through”-style cans like the Huxwrx Flow556?
Probably almost entirely unnecessary if you have a flow through/low back pressure can. Still a good option for the gajillion "legacy" cans out there.
@@Hoplopfheil thanks, this was my understanding but just wanted some reassurance. I appreciate it Big Guy bless up👌
I don’t know if this helps you or not but on one of my rifles I filed down the length of the screws so I could use an M lock slot close to my gas block to mount a bipod.
Of all your builds, I think this may be my favorite
I literally just randomly picked the anderson A4 dissipator video... and then saw this drop! I went to look for the upgrades videos and this dropped! Its like you read my mind through the internet. I tried to think of how... nearest I can tell the 5G waves were reading my thoughts that were amplified by the antenna created between my skull and the the toilet bowl. The pushing energy and yelling sent this message back in time to give you the idea for the video!
This means there should be an A-Team and Baywatch reboot any minute! Woot!
Hop, you should do a video about the different suppressor mounts you have and your opinion! Sounds like a great watch (even if you mumble on)❤️
I used the rainier 16" dissy barrel, a2 front post and a brt tube. A2 rifle stock and buffer and even with a turbo t2 its still a good shooter.
16:28 grind down the QD. it really only needs 1/16" past the bearings looks like you have the ferro concepts QDs. I filed mine down to 1/8 pas bearings. Held for 4years and counting.
my only gripe with the rifle speed gas block other then price, is the weight. The shortest one is nearly 4 oz and get heavier as you go longer. Added to the fact that they get installed at the far end of the rifle only makes the additional weight feel worse.
I like to strip any unnecessary weight from my builds and use an adjustable gas block to make sure the BCG still cycles properly. I would love one of these but only if they made them lightweight. Maybe aluminum or titanium for the body and steel where it really matters. If they can cut the weight to one or two Oz. I'd buy several
Im in the process of building a 16" upper that'll primarily be suppressed. It has an intermediate gas system. Im going run the RS7533 gas block with a 13.5" hand guard. Hopefully it works out nice.
Glad you make these videos.
I can picture a set of Aero receivers with the built in rail interface working out well for a build like this, plenty of room under there and I think they make a 13 something, have to look now. BTW after seeing how this worked on your 308 build I'm going to give one a try on a large frame frakengun I'm working on.
Hey Hop, would you also like a set screw for your set screw's set screw?
That’s a lot of dissipation
It would be nice to see the accuracy of this build compared to a similar build with a more standard gas port location.
I doubt that has anything to do with it, but Focus Tripp tested groups with his barrel.
@@Hoplopfheil it would be nice to see if it does. Even if it just confirms your suspicion that it does not. :-)
This is long and i'm sorry, but i'm trying to help add to the hive mind of information about this type of build because i really enjoy it lol.
I have one of those barrels, although its not in a build yet. Even though its a dissipator barrel, its gas port is much larger than I think it needs to be at .121. 20" rifle barrels are usually like .098 in the TDP I think. Of course, the TDP doesn't account for crappy commercial ammo, crappy commercial grade parts, or that its shorter dwell time. So naturally, a increase in size should be added to the port when considering the variables we need to overcome, like you rightly mentioned (or eliminate some of those variables). But I would argue that margin isn't 23 thousandths, rather its more like 5 to 10, which is still a bigger swing than you'd think.
Its the same issue Focus Tripp described on your 12.5 mid from KAK. They apparently don't' care enough to perform testing to find out what's an appropriate size OR they are fighting leaky / inefficient gas systems and aren't aware of it. Could that be why the K-Spec exists? To vent gas elsewhere from their ridiculous gas ports?
Ejection pattern is not gospel, but i am using it here get a ballpark idea. The 16" rifle gas AGP barrel from "Special Ops Tactical" (the trifecta of cringe company names) has a smaller gas port than that of the KAK (im pretty sure). I can't remember the exact size, I need to go re-check it cause I can't find it in my notes. But I run it with a standard BCG (gauged efficient), non adjustable block, A5H2 (w/standard spring) and a turbo t2.
Off the shoulder test held in my hands only. Gun is new but around 500 hundred rounds fouled and on the cusp of needing more lube (i use grease). Upper is milspec forged, so the brass deflector is the standard profile. Rainy and mildly cold weather. One round at a time, all rounds locked back on a empty mag - Unsuppressed: despite the A5H2 (effectively an h3), the gun ejects at 3 o clock sharp with Tula and ejects around 2 with Federal XM193. / Suppressed (turbo t2): ejects at 1 with XM193 and around 1:30/2 with Tula.
The unsuppressed behavior with a smaller gas port than the KAK barrel is whats most interesting to me. lt leads me to believe the KAK is way over-sized beyond a safety margin for conditions and ammo variables. Your Anderson's behavior was obviously different which is also interesting. I theorize a difference in ammo and gas system efficiency to be the difference there most likely. But i would go as far to say if you sealed the gas tube at the FSB with loctite 620 and got a carrier that was efficient (gas key doesn't leak + gas key is proper size + bolt tail seal proper size + gas tube proper size), it would probably run completely different; and i'd be willing to bet that at least 2 of those variables are inefficient on the Anderson.
A sealed up efficient gas system makes more of a difference than people think in running crap ammo in bad conditions. Rather than taking up the slack for crap parts by hogged out gas ports, I wish manufacturers would just learn how to build and qc gas efficient parts. BCM apparently gauges their BCG's with air volume to check efficiency. Supposedly no other manufacturer does that.
Can confirm, 12.5 mid with 10.5 and shortest riflespeed gas block collat configuration is excellent.
Awesome video. Thank you! 🤙🪖👮🙏🇺🇲
