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 Bolt Carrier Group (BCG) comes fully assembled and ready to drop into most mil spec AR15 upper receivers. All critical parts are coated with EXO Nickel Boron technology that provides permanent dry lubricity, extreme durability and increases both wear and corrosion resistance. FailZeros patented Nickel Boron coating will reduce friction and improve the overall performance of your rifle.
Nickel Boron treated parts include:
Bolt & Extractor (5.56/.223/300 Blackout compatible)
Bolt Carrier
