Bolts & Bolt Carrier Groups

Your bolt carrier group is the beating heart of your firearm’s gas impingement system. Using the gas from your previous shot, your BCG will cycle out the spent brass, reset your hammer, and help chamber the next round. A good bolt assembly is machined to exact specifications to ensure proper gas system functioning. We offer high-quality lightweight BCG options that provide superior performance while weighing in well under similar products like the BCM bolt carrier group. Take your build to the next level with the increased durability and reliability of an upgraded BCG.
