Constructed from stress-relieved 4140 steel, this barrel maintains dimensional stability under repeated firing cycles. The nitride finish, a thermal-chemical process, creates a hardened surface deeper than coatings like phosphate, significantly improving bore life and ease of cleaning. For the 5.56 NATO chambering, proper gas port sizing is maintained to ensure reliable cycling with both .223 Remington and 5.56x45mm ammunition.
