CMC TRIGGER ENHANCED BCG STANDARD AR10 .308/6.5CM NITIRDE FINISH MIL SPEC 81633

Those who demand premium performance from their AR 308 rifles focus on a number of elements within their rifles in order to boost durability, precision and reliability. One of those key components is the bolt-carrier group, and the CMC Triggers AR 308 Enhanced Bolt Carrier Group is purpose-built to enhance functionality in your short-action AR.

Each CMC Triggers AR 308 Enhanced Bolt Carrier Group is machined from case-hardened 8620 steel and features a flared rear assembly that prevents the carrier from canting or tilting during recoil. The carrier also features relocated bearing surfaces designed to ensure smoother, more-reliable function. Three forward ports allow gas to escape in the event of an overpressure round, and the bolt carrier itself is optimized for use with suppressors.

Within the bolt carrier itself is the bolt assembly, which features true mil-spec dimensions and external surfaces that are CNC-ground after heat-treatment in order to ensure precise tolerances. The bolt is constructed from 9310 case-hardened steel and features a low-friction, black-nitride coating. The bolt is designed for use with 7.62 NATO cartridges and related rounds.
