FailZero AR-15 Semi Auto Bolt Carrier Group (BCG) Matte comes fully assembled and ready to drop into any mil spec AR15 upper receiver. All of the critical parts are coated with FailZero's EXO Nickel Boron which provides permanent dry lubricity, extreme durability, corrosion resistance and will reduce friction and improve the overall performance of your AR-15 based rifle.

Wet lubrication is never needed. The EXO Technology dissipates heat so efficiently that the rifle will run cooler and cleaner since wet lubrication isn't needed.
