Description
This NBS Black Nitride .308 Complete BCG is compatible with any AR10, 6.5 Creedmoor, .308 or 7.62×51 rifle that follows the DPMS pattern. The carrier includes forward assist serrations and the bolt is (MPI) certified. The double ejectors address the problems most rifle builders encounter with AR10 variant calibers, and with the addition of a second ejector, you can expect flat loading, powerful and consistent ejection.
