The included mil-spec length bolt pairs with a longer Black Rifle Arms Enhanced Firing Pin for better performance without over-penetration.
Note: despite the included enhanced firing pin, light strikes may still occur when shooting TulAmmo or Golden Tiger ammunition due to excessive primer depth.

Great BCG! one question, does this work and feed ak magazines with a psa ks47 lower?
Finally its reliable
by Rob
I have a radical firearms upper, that has never let me shoot steel casings reliably. I've upgraded to the enhanced firing pin, new trigger, buffer and spring, but with steel golden tiger ammo (yes I know it's cheap surplus junk), I'd always get a misfire or two every ten rounds. Once I dropped this BCG in, I went 50 rounds without a single misfire. I was skeptical reading the description on the website, even says it may not solve light strikes on steel casings, but it seems to have done the trick for me.
Awesome product

This is my second FailZero 7.62x39 BCG. Unsurpassed quality with NiB, enhanced to the max. Great value. Highly recommended.
FZ 7.62x39 BCG
by NavyCWO4 -
Purchased "on sale" - super value for an exceptional NiB bolt carrier group. A drop-in BCG that runs steel or brass out of my 10.5" 7.62x39 pistol. And, the best part is Primary Arms FAST shipping. The best in the business !!
Great for 7.62x39 uppers.

I have built 4 7.62x39 uppers with this BCG with 100% reliability through thousands of rounds of steel cased Russian ammo. This is the only BCG I will use for my x39 builds. Excellent product!
Fail Zero rules!

I have a Fail Zero BCG at the heart of my .458 socom build and I couldn’t be happier. I’ve not had a single malfunction with it. In my haste to shoot it, I forgot to lube it and the upper receiver. Functioned flawlessly, I’m completely satisfied.
Pretty good.
