Fail Zero Assembled Bolt Carrier Group, 6mm ARC, Nickel Boron

The Fail Zero 6mm ARC Bolt Carrier Group (Fail Zero part no. FZ-6mm-ARC-NH) comes fully assembled and ready to drop into most mil-spec upper receivers chambered in 6mm ARC. All of the critical parts, including the 6mm ARC bolt and extractor, the M16-cut bolt carrier, cam pin, carrier key, and firing pin, are coated with Fail Zero’s EXO Nickel Boron technology, which provides permanent dry lubricity along with extreme durability and improved wear and corrosion resistance. Because the coating does not rely on added oil to function, cleanup is faster and the rifle can run reliably even when it is not freshly lubricated.
