FailZero Nickel Boron EXO 7.62x39 BCG w/ Enhanced Firing Pin
Fully assembled and ready to be dropped into any mil-spec upper, this bolt carrier group from FailZero has had all its critical parts coated with EXO Nickel Boron. The result is a permanent dry lubricity, increased corrosion resistance and extreme durability. This finish is especially important for a 7.62x39-chambered rifle, as that caliber of ammo is known to be corrosive on components over time.
The bolt portion of this BCG maintains mil-spec length for reliability, while the extractor hardware includes a heavy spring, silicone insert and O-ring for better tension. It also includes a Black Rifle Arms enhanced firing pin that has a longer length for better performance without risk of over penetration. The longer firing pin also helps eliminate light primer stires, which are notorious with 7.62x39 ammo. All these components together means you can shoot most Russian ammunitions, including Tula.
FailZero BCG features:
- 7.62x39-compatible bolt and extractor
- M16 cut bolt carrier
- Cam pin
- Carrier key
- Enhanced firing pin
