Not sometimes. RUclips is demonetizing many gun content related YT channels for BS reason plus they keep changing their policies restricting more and more what these channels can actually include in their videos
A 124gr projectile at 1100fps has 333 ft-lbs of muzzle energy; a 55gr projectile at 1712fps has 358 ft-lbs, a gain of 7.5%. Is that, as the immortal Mr. Harrell says, enough difference to make a difference? And is it worth the tradeoff in concealability vs. a 9mm handgun? You be the judge.
@@lancegardner8560 You have lost your mind. There are many videos showing it over and over....its the entire point of the barrels being that short, for targets up to 100 yards and closer.
7.5 isn't THAT dumb...it just isn't as good as a 10.3 but 10.3 isn't that great either...ppl say they stop at 10.3 well the range and energy still isn't very great
I use an adjustable gas block on mine. I built mine using the KAK 4.75" barrel and I have had zero malfunctions. I am using the original Pantheon Arms short buffer tube (Kentri) systems and it all works fine. I turn down the gas until it fails to cycle and then gradually turn it up (I use only green tips) until it cycles reliably. I'm using a Faxon BCG
@@pewpewtactical Awesome! That's good that it's shooting reliably now. My primary reasons for using the adjustable block was so that I could turn down the pressure to prevent hammering the buffer assembly. The pressures of the gas exiting that close to the chamber has to be substantially higher than even out of a short/7.5" pistol gas tube. I want it down to rifle or carbine pressures. If that makes sense.
For me, the real comparison is between this and a 9mm handgun. I would think of it as like a step up from a handgun into the PDW role than can punch through any soft armor and prioritizing max concealibility over even a 10" AR. It definitely niche, kinda like a MP5k. Additional performance out of a 5.56 over 9mm with the tradeoff of TONS of concussion. Perhaps would be even better with a suppressor that doesn't have barrel length restriction.
Just picked up an aero precision epc-9 with a 5.5 inch barrel and it’s my smallest “pistol” so far. Extremely compact but probably a thousand times less blasty than this thing 😂 great video
I have the stainless version with a Noveske KX3 tucked under an aero enhanced handguard. I call it the "We have the PDX at home" 😆 An H3 buffer and flat wire spring is a must
Good question. The optic was already set up that way when I mounted it. Consider this: if you watch my mustache, you’ll see it wiggle every time I shoot. This is because of gases coming out of the buffer tube. I wouldn’t want that closer to my eye. I didn’t plan that, it just worked out that way.
@@pewpewtactical Thank you for taking the time to answer my question. Seems like ultimately finding a grip and firing position that makes sense for this weapon is the challenge.
@@thedownwardmachine For sure. I would also want to spend some time working on recoil mitigation. With a full rifle, squaring up the hips makes a huge difference, but this will take some experimentation.
Velocity is the one and only factor that makes a 55 gr .223 pill effective. I think people are genuinely ignorant to how much velocity they're losing out of a barrel this tiny. The standard cope is that even though the velocity has been reduced to pea-shooter level, it's perfectly fine because you're at close range and indoors. So why not use 22 WMR? These ultra tiny 5.56 guns are a recipe for unburnt powder, obscene muzzle flash and deafening noise levels.
@@pewpewtactical Thank you for your fast answer. I was confused to why some Mags Are blured and some Are Not. But I also wasnt aware that YT has also rules on magazines
1700 fps is still a lot coming out. I mean ya compared to a 9mm, that not even coming out at 1150 fps most of the time due to most 9mm pistol ppl used are under 4.25 to 3in, so to me its whatever floats your boat. Its still get the job done. Ya, i know most 9mm pcc use a 5in barrel or bigger to get them velocity, but again, whatever you're more comfortable with as long you train with it.
I think that’s an observation, but shouldn’t be the takeaway. Zero malfunctions after the BCG was replaced. I’m certain KAK would warranty it and make it right.
I am sure they will. I just find the concept of guns like this to be stupid. The entire reason I am shooting a rifle cartridge is VELOCITY. I would like to see Sig or someone make a dedicated SBR round and rifle. Use the BI metal case to create higher pressure so you can still get 3k velocity out of a 5" barrel. 556. is not really great when it falls below 2500 a second. Now that AAC is making 300 blk for the same price as .556 ...
These things are just noise makers with no practical purpose. A 7.5 inch AR is so loud that you need double hearing protection, I guess you could use this to disorient your attacker with sheer noise.
@@billyharper5925 I didn't say that it wouldn't kill someone, I said that it's not practical. They are so loud that it disorients the shooter and at night the flash would obstruct your vision. If a person wants one for novelty purposes it's fine but for self defense there are a lot better options.

Great points!
As if 7.5” wasn’t DUMB enough.
They built it: we came.
It's still good for 100yds and closer...
@@Raymo2uno it's not.

Morrissey has never sounded so good
🤣🤣🤣
This man didn’t strike me as a listener of the Smiths, but I’m happy to have been mistaken!
Used to wear a lot of black. 😅
I didn't think a barrel this short could even function
I had my doubts, but it was solid after the extractor, and performed better in accuracy than I would have guessed.

I turn down the gas until it fails to cycle and then gradually turn it up (I use only green tips) until it cycles reliably. I'm using a Faxon BCG
That's a good move. Once we got past the extractor, we had zero issues.

Hey thanks Ethan! Yeah I bet 5.5" would be a little more tolerable.
@@pewpewtactical being 9mm yes 🤣
EPC rocks!
As far as lights go you can do a 45 degree picatinny mount with a picatinny flashlight thats how i run my micro bulids
There you go, that makes total sense. Thanks!
That is nice being able to replace the bolt carrier 😁
You're absolutely right. Would be concerning in a defense scenario, but extractors do fail on occasion.
I really enjoy his style of weapon reviews
Thank you, it’s been an evolution. We spent quite a bit of time on this one and really try to balance between providing info and keeping it brief.
If its an .300 blk im in.. :D
I like it ! I have a folding 300 blk out with a 5" barrel it's not bad at all !
That makes sense considering 300BLK. I wouldn’t want to touch this one off in a house unless I had to.
I have the stainless version with a Noveske KX3 tucked under an aero enhanced handguard. I call it the "We have the PDX at home" 😆
An H3 buffer and flat wire spring is a must
It’s a flash bang!
💯
Why put a riser under an optic on a firearm you’re not going to get a cheek weld on?
Good question. The optic was already set up that way when I mounted it. Consider this: if you watch my mustache, you’ll see it wiggle every time I shoot. This is because of gases coming out of the buffer tube.

I love The Smith's cover tho.
It was either that or Big Mouth Strikes Again! 😆
Built a 9mm version. It's a blast!
Doesn't like that magazine. Thanks for sharing with us 🙏
I considered that, but all the mags ran great after the BCG was replaced.

All good points. An old timer I knew in Colorado used to take black bear with a .22 though shot placement was key.
Nobody is volunteering for a dose of Vitamin Pb even from this anemic 5.56 NATO pistol.
A Question from a non-american:
Why do you have to blur some of the magazines?
RUclips presents us with the challenge of ever-changing rules. We used a mag they probably wouldn’t be happy about.
@@pewpewtactical Thank you for your fast answer. I was confused to why some Mags Are blured and some Are Not. But I also wasnt aware that YT has also rules on magazines
@@P4Tri0t420 They don't allow magazines or belts over 30 rounds.
@@holdenroth5929 I feel so much safer now.
@@holdenroth5929Over 30 rounds, or 30 rounds or larger?
a 4.75" 5.56 is still kicking past 1500fps at 100yds
Yeah it's more spicy than I was expecting.
So you're basically throwing around half the energy of a 9mm handgun round.
A 22lr +p lol
A .22 lr won't zip through 3A soft armor.@@ImOldGregg
Sideways tho
Looks like a hard kick to the right though. Needs some better balance or a break or something.
Good eye. That was what I noticed too. I'd like to spend some time with it and work on technique.
@@pewpewtactical I bet you could balance it out a little. It looks slick though.
Dpms kitty cat coming back soon
Saw that, stoked!
1700 fps is still a lot coming out.

Very true. It makes me curious about terminal ballistics of a 5.56 at 1,700-1,800 FPS.
Training is EVERYTHING.
A sniper's weapon
😅😅 For sure!
It’s as accurate as the last AK I reviewed. 😂
My KAK is bigger
That may be true, but mine makes me happy.
@@pewpewtactical Fair enough. Hey now, I clean mine every now and then.
@@Raven_Enforcer 😆😆
KAK products are pretty good...but I hope that's not one of their new "fancy" bolt carrier groups...it's not a great look.
Creasy Bear!
@@pewpewtactical "I'm gonna do what I do best..."
@@oskar6661Yeah I’m impressed with it despite the extractor. The accuracy was much better than I’d expected.
I read Kit Kat... and it is a Kit Kat fun size lol
Seeing this makes me wonder if you could pack your own rounds with a lighter charge to make it more efficient and quieter...?
Good point. I didn’t have any subsonics but that would be interesting to try.
not even interesting. there is a point where an AR gets too small and this definitely is
The upper alone is only 460. The complete weapon is 674.
Would velocity be greater with 300blk and if so by how much ? Nice vid !
Thank you! That's a great question, and I'm not sure. I know .300BLK was optimized for shorter barrels, but I'm not sure about this length.
Great video! The beard is glorious btw 😅
Thanks! 😁
Im tired of hearing 4 inches isnt enough!
😤!!!
😂
The bolter
For the Emperor!
Great review. It is what it is! Compact 5.56 with combat accuracy. Just bring ear pro!
Great summary, and thank you!
It’s a jammer, no gracias….
4.75” barrel gonna cost ya 2.5 fingers
😂It was a struggle for me. I’m used to stretching out.
No sling mount.
Put it in your pocket? 🤷♂️
@@pewpewtactical Anorak/ hoodie cross-belly hand warmer pocket!
i like ur bracelets 😎
😉
I need one or 2, thanks
They’re pretty affordable!
Jams like a 1911.
🤘 😁 🤘
Big surprise, a 4" AR-15 is ripping the lip off the casing and malfunctioning...🤣
I think that’s an observation, but shouldn’t be the takeaway. Zero malfunctions after the BCG was replaced. I’m certain KAK would warranty it and make it right.
I am sure they will. I just find the concept of guns like this to be stupid. The entire reason I am shooting a rifle cartridge is VELOCITY.

A gun so stupid and pointless that even the Taurus Judge won't hang out with it.
Ouch.
These things are just noise makers with no practical purpose. A 7.5 inch AR is so loud that you need double hearing protection, I guess you could use this to disorient your attacker with sheer noise.
So would you stand 35 yards in front of it?
@@billyharper5925 I didn't say that it wouldn't kill someone, I said that it's not practical. They are so loud that it disorients the shooter and at night the flash would obstruct your vision. If a person wants one for novelty purposes it's fine but for self defense there are a lot better options.
@@MaxHavoc69 I wouldn’t personally use it as a home defense but it would make a nice lil passenger blaster.
Put a stock on that stupid thing
best ar is 16 inch ,,,,,,,,,
Sure, this is all about trade-offs.
Kak Is the issue😂
