One of FailZero's key innovations is their EXO coating technology, which stands for "exolytic treatment." This is a proprietary process that involves treating the surface of the metal with a nickel-boron coating, which results in increased durability, corrosion resistance, and lubricity. This technology is used in many of FailZero's products, including their bolt carrier groups, which are designed to provide smoother cycling, easier cleaning, and improved reliability.
FailZero 224 Valkryie/6.8 SPC Bolt Carrier Group (BCG) comes fully assembled and ready to drop into most Mil-Spec upper receivers chambered in 224 Valkryie/6.8 SPC. 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 and will improve the performance of your rifle. This 224 Valkryie/6.8 SPC bolt assembly is also compatible with the 6.8 SPC II cartridges. The Extractor hardware includes a heavy spring, silicone insert, and o-ring to give better extraction tension.
Nickel Boron treated parts include:
