Just finished an AR 9 build and ran into a problem.
Engage colt pattern lower
Engage upper
ALG lower parts kit with ACT combat trigger
CMMG bolt
Pistol buffer tube
Tubbs flat wire spring
Slash's Heavy buffer 9mm buffer 9oz
Brownell's 32 round mags
11" Ballistic Advantage barrel
Gemtech 9mm Tundra can
Testing started out great. It ran 115, 124, 147 grn ammo perfectly without the can. 147 grn with the can started out good, ran through about a 100 rounds with out an issue. Since everything was going so well, I decided to run it hard. Loaded up two mags for mag dumps, at the end of the second mag the bolt catch broke.
I am assuming I need to slow this down some more. Slash's does offer a heavier 12oz buffer, but it's kind of pricey at $140. Any other options? Defective bolt catch? Am I missing something else?
