FailZero is the undisputed pioneer of Nickel Boron technology. When failure is not an option, you can depend on Fail Zero.

This 7.62x39 Bolt Carrier Group (BCG) comes fully assembled and ready to drop into most mil-spec upper receivers chambered in 7.62x39. All critical parts are coated with EXO Nickel Boron technology that provides permanent dry lubricity, extreme durability and increases both wear and corrosion resistance. EXO Nickel Boron makes for easy cleanup even with the corrosive 7.62x39 ammo and will improve the performance of your rifle.

The bolt keeps the Mil-Spec length for a more reliable bolt. The Extractor hardware includes a heavy spring, silicone insert, and o-ring to give better extraction tension. Included is a Black Rifle Arms Enhanced Firing Pin that has a longer length as well as other dimensional changes beyond overall length for better performance without over penetration. Due to the Mil-Spec bolt length and enhanced firing pin, you can shoot most Russian ammo including Tula.

Note: Tula Ammunition and Golden Tiger have issues where some primers are set too far in and will still cause light strikes even with an Enhanced Firing Pin.

Nickel Boron is an extremely durable finish with self-lubricating properties so your AR15 cycles smoother and requires less lubrication. Fail Zero BCGs are plated by UCT Coatings of Palm City FL, the same company that does it for Toolcraft.  

Called EXO Technology, this is a patented process that applies a Nickel Boron finish so durable that it is specified on Army 81mm and 60mm mortar tubes, Blackhawk helicopter hoists, and for hard use applications on some Navy ships!  IMO, this may be the ultimate AR-15 upgrade. And it looks good too!
