KAK Industry K-SPEC Enhanced BCG 5.56 – Dual Ejector, Desert Chrome

The KAK Industry K-SPEC Enhanced Bolt Carrier Group is a complete replacement BCG for AR-15 pattern rifles chambered in 5.56 NATO/.223 Remington. This enhanced design features a dual ejector system for improved extraction reliability and reduced ejection failures, particularly beneficial for suppressed firearms or rifles with non-standard gas systems. Built to exceed mil-spec standards, it replaces factory or worn BCGs to restore or improve cycling performance.

Machined from 8620 steel with a Carpenter 158 steel bolt, this BCG features a desert chrome finish that provides enhanced corrosion resistance and lubricity compared to standard phosphate coatings. The dual ejector configuration increases extraction force and consistency. Installation is drop-in for any mil-spec AR-15 upper receiver—no gunsmithing required. Bolt is properly staked and MPI/HPT tested.
