The case hardened 9310 steel bolt is shot peened for hardness, then HPT/MPI tested. The bolt lugs are CNC ground after heat treating to ensure the best fit and greatest accuracy. Then it's all self lubricating black nitride treated! This may seem like is rare high quality production in the firearms industry, but just a normal days work for AXTS Weapon Systems.
