Manufactured by Fail Zero

Details

This 7.62x39mm Bolt Carrier Group is fully assembled and drop-in ready for most MIL-SPEC upper receivers. All critical parts are coated with EXO Nickel Boron technology providing permanent dry lubricity, extreme durability and increased wear and corrosion resistance. This patented Nickel Boron coating will reduce friction and improve the overall performance of your rifle.

NOTE: In spite of the included Enhanced Firing Pin, light strikes may still occur when shooting TulAmmo or Golden Tiger ammunition due to excessive primer depth.

Features:

MIL-SPEC length bolt
M16 cut bolt carrier
Black Rifle Arms Enhanced Firing Pin
Magnetic particle inspected
Live fire tested
EXO Nickel Boron treated parts include:
Bolt, extractor, bolt carrier, cam pin, and carrier key

Includes a reliable MIL-SPEC length bolt and a longer length Black Rifle Arms Enhanced Firing Pin for better performance without over penetration. The extractor includes a heavy spring, silicone insert, and O-ring for improved extraction tension. Not all Nickel Boron is created equal and FailZero is the undisputed pioneer of Nickel Boron technology. When failure is not an option, you can depend on FailZero.

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.

by Edward -

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

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 !!
