I bought the 7.5 Gen 2 762x39 Found gas block loose straight out of the box ensured holes lined up with and blue loctite tried multiple lowers h2 and h3 buffers and springs cant get pistol to cycle tried 1 round bolt gold open passes every time, also checked bolt carrier lubricated and extractor is ok, also spring is nice and hard no issues with bolt carrier, does not eject round most of the time any ideas anybody? Also tried different ammunition
Very nice 👍 I’ve recently ordered the exact same upper, mine has a side charging handle though. Are you doing more videos of this build? I would love to see you shoot it.
@@liberalgun the 556 round works because of the velocity with that short of a barrel it does not have the Velocity and that basically nothing but a 22 magnum
That’s one of those ‘Internet facts’ that isn’t quite accurate. I’ve shot filled 2 liter bottles with magnums in the past. I can assure you the AR pistol hits the same filled bottles harder - at least at close range. If you start extending ranges things could change, but up close I don’t buy into the claims a 5.56 pistol isn’t effective. At the very least, the obnoxious concussion is a weapon of its own. There is also the argument to be made for having one ammo type/mags/parts, etc.
I don’t own a chrono, but I did look up muzzle velocities from others, and 55gr 5.56 on a 7.5” barrel is ~2400fps. A 50gr 22 mag fired from a 24” barrel is ~1530fps. Even with the longer barrel the 22 mag doesn’t have the speed of a 7.5+5.56 combo. No comparison. Especially considering the 22 mag would be reduced even more if fired from an equal 7.5” barrel.
liberal gun owner huh? sounds lonely. I do love bca though! im still trying to wrap my head around the whole liberal gun owner thing. do you think that some guns are ok but not all? you apparently have no issue with ar's. do you just pinch your nose and vote for liberals who want more gun control? help me understand how this works. please dont take this as evidence that im a republican/ conservative. neither describe me well, nor does "liberal" like most americans i fall somewhere in the middle.
I'm not wasting any more Ammo with my BCA 556 Upper. It's all over the place at 25y shooting iron sights & Red Dots. I've tried 55g, 62 m855's seem to be the worse & 75g Hornady Match Grade 556. It's shooting center on 1 shot, then 10" high or low on 2nd & 3rd shots. It's just not accurate & all over the place My 16" drives Sub MOA at 100y easily but this 7.5" is just junk
Really growing more and more fond of pistols under 8”.
You can just pull straight back on that brace without pushing any buttons.
What buffer weight
I have almost the same setup, but I have the side charge. My cheapest build, but my favorite!
I have the same setup. But a Areo Lower... it’s my go to AR! love the size and portability

What is the length of pull from brace to trigger
I have a complete BCA 7.5 5.56 and it is loud but works.
It looks good .

I don't understand why people build a 556 pistol they obviously don't understand how the round works
Make your case against it. I would like to hear your reasoning.
