All of our barrels are nitride heat-treated to a case of 70 HRC. Our barrels shoot consistently better groups on all of our weapon systems than chrome-lined barrels after a high round count. Our barrels are easier to clean and don’t copper foul like chrome-lined barrels. Chrome lining can separate away from barrel surface over time. Chrome lining also does not plate evenly on the entire surface of the bore and grooves.
