The LBE AR-15 Complete Bolt Carrier Group (brand part no. AR15BLT) ships fully assembled and ready to install, whether it’s going into a fresh custom build or serving as a backup BCG for a rifle that sees regular use. LBE Unlimited, a US manufacturer of gun parts and accessories, builds this bolt carrier group as a complete unit so builders don’t have to source and assemble individual bolt, carrier, and cam pin components separately. Having a spare BCG on hand is a practical safeguard for any AR-15 owner who depends on their rifle, since a cracked bolt or worn extractor can otherwise sideline a build indefinitely. This is a straightforward, functional BCG for anyone finishing a build or stocking a spare.
