CMC Launches New Line of Barrels

CMC Triggers announced a new line of CMC Barrels. Since 2018 and the launch of the CMC Glock Match Precision Barrel, CMC has been developing a series of high-quality AR Barrels that complement their line of AR aftermarket products. Now with the CMC Barrels, they have done just that.

CMC Barrels

CMC received input from military, law enforcement, and civilian shooters incorporated into the core engineering and design. Every barrel is precision, instrument-inspected for absolute straightness and air gauged for maximum uniformity, yielding the highest accuracy possible. Land and groove tolerance from breech to muzzle can vary only .0001″ for the best concentricity.

The first profiles available are based on the SOCOM variant. The AR15 Barrels are made from 4150 Chrome Moly Vanadium, coated in H&M Blacknitride+ for increased wear resistance, chambered in .223 Wylde so that you can feed it both .223 and 5.56 NATO ammo.

The Barrels provide your choice of gas system lengths, along with M4 feed ramps for reliability, a 1:7″ twist rate, 1/2″x28 thread pattern to fit standard AR15 muzzle devices, 11-degree match crown for increased accuracy and a bottom dimple for easy install and alignment of gas blocks. 


The CMC AR15 Barrels are coated in H&M Blacknitride+ or Ferritic Nitrocarburizing, resulting in significantly improved surface properties on ferrous metal parts while maintaining dimensional and shape stability. H&M Blacknitride+ yields increased wear resistance, improved fatigue strength, better corrosion resistance, improved lubricity, and enhanced cosmetic appeal.
