Finish your AR-10 build or upgrade your old one with the Guntec USA .308 bolt carrier group. This BCG is designed for tough use with its hardened steel bolt, firing pin, and extractor that won't break under stress. The carrier is made from 8620 steel and has a Nickel Boron coating that is harder than chrome and more slick allowing you to shoot longer between cleaning. It also makes cleaning easier as the carbon buildup will simply wipe off. The gas keys are also properly staked to ensure it won't back out over time.
