Anyone who knows us, knows our BCG’s. We test fire every unit in full auto after inspection, to guarantee our customer receives an efficient BCG they can trust for life. We HP/MPI inspect every bolt individually, upgrade the extractor spring with a Sprinco enhanced 5-coil spring, and deeply stake the gas key once it’s torqued with Grade 8 fasteners.![]()
In addition to our standard BCG’s we also offer a Chrome option, as well as special edition BCG’s assembled with O.C.K.S. fasteners in place of Grade 8. These optimized screws hold the staking on the gas key even more deeply, further minimizing the possibility of the gas key loosening.
Beyond our standard caliber BCG (5.56mm/.300BLK/6mm MAX), we also offer BCG’s for .308 Winchester, 6.5 Creedmoor, 6.5 Grendel, and 6mmARC
