The Fail Zero 6.8 SPC Bolt Carrier Group without a hammer (Fail Zero part no. FZ-6.8SPC-01-NH) comes fully assembled and ready to drop into most mil-spec upper receivers chambered in 6.8 SPC. Every critical part is coated with Fail Zero’s EXO Nickel Boron technology, which provides permanent dry lubricity along with extreme durability and increased resistance to both wear and corrosion. Because this BCG ships without a hammer, it’s built for builds where the hammer is sourced separately or already installed in the lower’s fire-control group, keeping the BCG itself focused on the bolt, carrier, and gas key components.
