KAK Industry K-SPEC AR Bolt 5.56/300BLK – Desert Chrome Finish

The KAK Industry K-SPEC AR Bolt is a replacement bolt designed for AR-15 platform rifles chambered in 5.56 NATO or 300 Blackout. This bolt replaces worn or damaged factory bolts and restores reliable cycling and extraction. The K-SPEC designation indicates KAK's quality control standards for material hardness, dimensional tolerances, and proper gas key staking.

Manufactured from 8620 steel with a desert chrome finish, this bolt provides corrosion resistance and reduced friction during operation. The finish also aids in cleanup after extended shooting sessions. This is a drop-in replacement part, though proper headspace verification is mandatory after installation—professional gunsmith installation is recommended to ensure safe function. The bolt does not include a cam pin, firing pin, or extractor.
