Bear Creek Arsenal products complete their entire production cycle at their Sanford, North Carolina facilities. Drilling, reaming, rifling, and turning are all performed on CNC machines under ISO-9002 Quality Systems, allowing Bear Creek to precisely control each step of manufacturing. Careful inspection ensures each barrel meets their stringent standards before shipping.

This AR-15 barrel is machined from 4150 chrome moly vanadium steel, heat treated to RC 28-32 hardness, properly stress relieved, and Parkerized for a corrosion resistant finish. BCA guarantees 1 MOA groups at 100 yards when observing proper shooting techniques and using high quality ammunition.

NOTE: Barrels shorter than 16” in length are only intended for use in AR-15 pistol builds or legal short-barreled rifles. Other configurations may violate Federal law.

Bear Creek Arsenal does not recommend using steel cased ammo in their assemblies or rifles.
