Under rated - FailZero AR10 .308 Bolt Carrier Group (BCG)

I've put well over 1000 rds through this bcg. The 10 is a maintenance-after-every-use platform.The only issues I encountered where a bent retaining pin due to build up in the breach. Some sub-par, low cost, alternative, steel cased and likely manufactured in you-know where under you know whos administration, ammo and excess residue made for a sticky extraction thus bending the retaining pin. I made the exchange from cotter pin to machined pins and even bent a few of those! that and as to be expected crack forming on the extraction claw after the first 500 or so rounds. These rifles are no-doubt precision and a muzzle brake for the sake of your optics will reduce additional stress. 1500+ rds and nothing other than the afore mentioned.
