Aero Precisions AR-15 BCG with the 9310 bolt and nickel boron coating is a high quality piece. NiB cleans easily. The finish is more glossy than matte from the NiB process. Functions exactly as expected with proper headspacing.
Aero Precision AR-15 BCG with 9310 bolt and nickel boron coating ran tight for the first 50 rounds before breaking in. Now cycles smoothly. NiB cleans easily with a rag. Bolt is HPT/MPI tested. Solid budget NiB BCG.
