KAK Industry K-SPEC Enhanced Bolt Carrier Group – 6.5 Grendel

The KAK Industry K-SPEC Enhanced Bolt Carrier Group is engineered for AR-15 pattern rifles chambered in 6.5 Grendel. This BCG replaces factory carrier groups with a precision-machined assembly designed for reliable cycling with the higher bolt thrust and unique pressure curve of the 6.5 Grendel cartridge. Shooters upgrading to 6.5 Grendel or building a dedicated upper will appreciate the proper bolt geometry and headspacing specific to this caliber.

Machined from 8620 steel with a phosphate finish, this BCG features a properly staked gas key and MPI-tested bolt for durability. The dual ejector design improves extraction reliability. Installation is drop-in for any mil-spec AR-15 lower receiver—no gunsmithing required. Includes bolt, carrier, cam pin, firing pin, and retaining pin.
