Had this bcg for over a year and it's been great. The bolt head spaced perfect on a budget 308 upper/ barrel and just upgraded the barrel to a Faxon barrel and still head spaced great. The rear contacts the buffer as it should yet many others don't. And to top it off the coating fail zero uses is sooo soooo soooooo easy to clean and lube.

After careful consideration, I chose this BCG because of the company's commitment to quality. I ALWAYS purchase Made In USA whenever possible for all obvious reasons. The Nickle Boron coating is PERFECT! I could not be happier with my purchase.

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.

First off, love Fail Zero BCGs. I will continue to purchase Fail Zero prducts for 556 or 300 systems, but I will never purchase another Fail Zero for a 6.5 Creedmoor. The 6.5 is such a high pressure round, that standard 308 BCGs are unable to contain the pressure and the firing pins are too long. On my second round, the firing pin pushed through the primer, which blew the primer into the BCG, completely destroying the firing pin. The bolt assembly locked into the star receiver of the barrel. After about a dozen kickstarts, I was able to dislodge the bolt. I have since removed the bolt assembly and replaced it with a JP Enterprises high pressure bolt assembly, which costs as much as the Fail Zero BCG. I was lucky that it did not damage my carbon fiber barrel, but that's not always the case. Beware if you're running a 6.5, especially with a match barrel.

Haven’t tested yet. Fits into aero M5e1 308 upper with no issue, just questioning the lack of the FZ logo on the right face, haven’t read anything online about a missing logo but i thought it was strange it doesn’t have it
