“BA is Bada**, I have a few of their barrels now for my ar builds and the produce fantastic results if you do your part. This 9mm barrel I put together with a foxtrot mike lower and bolt function flawless and the barrel put a tight 1 inch group at 50yards with cheap target ammo, also thus barrel has great chamber support so no burst or bulged cases with hotter ammo.”
“Installed easy enough into a Aero Precision XL upper with toolcraft bolt carrier group. Also used Areo BAR nut and quantum hand guard. Needed two shims to get alignment right.”
“The company is great. I have 3 of there barrels 2 223 1 9mm. The 223 are truly 1/2 MOA all day long. The 9mm is great as a real PCC competition barrel. I get a 2 3 MOA at a 100yd with it. Now I use a dot not a magnified scope so that's pretty darn good. The 9mm bullet is not really made to be shot at a 100yd.”
