The Fail Zero EXO 6.5 Grendel Bolt Carrier Group (brand part number FZ-6.5-Grendel-01-NH) is a fully assembled BCG built to drop into most mil-spec upper receivers chambered in 6.5 Grendel Type 2, and it ships without a hammer for builders who already have one on hand. Every critical part is coated in Fail Zero’s EXO Nickel Boron finish, which provides a permanently lubricious surface along with a real boost to wear resistance and corrosion resistance. That coating also means fouling wipes off in seconds instead of requiring a scrub brush. The result is a bolt carrier group that cycles smoother and cleans up faster than an uncoated equivalent, while dropping straight into a 6.5 Grendel build.
