From the manufacturer
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 Mfg: Cmc Triggers
