Fail Zero rules!
by Jimmy
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.
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!
FZ 7.62x39 BCG

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 !!
