Our BPX9 barrels are precision machined from 416R stainless steel with an oversized lock up area for a "match grade" feel and made in the USA. The barrels are stress relieved and heat treated to 40-42 HRc before refinishing. Black Nitride refinishing is applied for maximum durability and hardness reaching 52-58 HRc on the Rockwell scale. Our Black Nitride also meets AMS 2753 specifications, improves fatigue strength, provides exceptional lubricity with a low coefficient of friction, improved wear and corrosion resistance all while holding dimensional requirements with little to no distortion.
