The CMC Triggers BBL556003 AR Barrel 5.56 NATO 16″ Black is a precision-engineered barrel designed for modern AR-15 rifle builds. Made from 4150 Chrome Moly Vanadium and coated in H&M Blacknitride+ for increased wear resistance, this barrel delivers durability and corrosion protection for extended field use and training applications.
Built to exacting specifications, this barrel is precision, instrument-inspected for absolute straightness and air gauged for maximum uniformity, with land and groove tolerance from breech to muzzle varying only .0001″ for the best concentricity. The barrel features a 16″ length with a 1:7″ twist rate, optimally suited for stabilizing a wide range of 5.56 NATO loads. When using factory-loaded, SAAMI-approved, Match Grade ammunition you can expect 1 MOA level accuracy (or better) out of CMC barrels at 100 yards.
CMC incorporated input received from military, law enforcement and civilian shooters into the engineering of their AR15 barrels to accommodate modern-day shooting requirements, making the BBL556003 a reliable upgrade for shooters seeking enhanced accuracy and performance.
