This was a cool video. I think I'm hooked!
How your historian and gunsmith didn't ask for a clarification if you really meant caliber or cartridge shows he's not much of a historian or gunsmith.
If you are getting a 22lr conversion kit that's not a caliber change, that's a cartridge change. 223 Rem and 22lr are the same caliber but different cartridges. Please gun community, know the difference and use the terms correctly.
It's hilarious to see videos where the gun community mocks anti gun people for their lack of understanding of terms yet our same gun community often uses cartridge and caliber incorrectly.
Is that Firing Line Range? I love that place.. I built my 9mm on the Mean EndoMags so I stay with the PMags….
Wth happened to Randy
BCA AR 10/8.6 BARREL/6.5 CREED BARREL/308 BARREL/22-250 BARREL,ALL USE SAME MAGS .,.TOTAL COST $ 875🤔🤔🤔🤔I WIN😊
Which pistol grip is that?
That Sylvan Arms Glock magwell conversion is over $100. I enjoyed this video but CJ saying “it’s only a few dollars” is incredibly misleading
Hey AT3 team, just wanted to say I love you guys.Your passion and fun shows through!Thanks for the awesome videos
Is it possible to do this with 9mm, 223/556 and 300 bklout? I love this idea fellas!
Neither picked a heavy buffer to remove the recoil. How do you get the 9mm to work with a regular Carbine buffer? The recoil appears to be heavy. This is a great beginner's level pick and build. I would think AT3 would want to teach people how to do it right, rather than the gamer, lost method. That mag adapter costs more than a new lower designed for 9mm. This video makes this adapter appear to be cheap, not the $100-$220 it is. I not being critical, but I am pointing out reality! The 22LR is a cheap move, I was hoping you would try a real challenge, which is what the customers do. I have the 6mmARC for long range, 6.5 Grendel for medium range, and the 300 Blackout for short range, all 3 together under a $1000.
That would be simple.
556, 300 Bk, 350 Legend
555/223/22lr with only a diff bcg
it is a big "it depends" . Are we starting off with a complete lower already built? Or are we building it, too?
Yes. I have a lower that I can use with 6 ARC, 5.56 and .300 BO. Just have to change out uppers. All 3 uppers and the lower costs less than $1k, easily.
To save time on 9mm, Endomags, they can be found sometimes for 20 bucks. Uses a standard lower too.
AT3 about to do a whole series of Sam ASMR build videos with his whisper voice, aren’t they?
absolutely if you make .22 and 9mm count. But yeah, you can build cheap uppers and switch them out
Its called an upper receiver and a magwell and bolt modification
As a fellow YouTuber, I love this channel! You all are absolutely fantastic! Truly one of my Favorite channels!
So,…if you went with a
223 Wylde, does that satisfy 2 out of the 3?
Different cartridges…
I JS.
