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 16" barrel is machined from 4150 chrome moly vanadium steel, heat treated to RC 28-32 hardness, properly stress relieved, and finished with a highly corrosion resistant salt bath nitride. BCA guarantees 1 MOA groups at 100 yards when observing proper shooting techniques and using high quality ammunition.

Barrel thread listed wrong

Great product that’s well made. Thread pitch is wrong though. It’s a 5/8x32 not 5/8x24.
