How many times have the pros on here said. Quality, known manufacturers none of these small time outfits using unknown sources.. Oh wait it’s a Springfield Armory..
That was my first thought too. Unless it’s a Wilson or LMT or xyz it’s crap and it’ll break. I’ll catch a load ofshit but I have 2 new BCA uppers that now have over 500 rounds each (I know it’s not a torturous amount but...) I haven’t had one malfunction from either one. Both are 7.63x39.
I have seen a metric chit ton of Bushmaster, DPMS, etc have issues right from the start.
