First Look: CMC AR Barrels in .223 Wylde

posted on March 15, 2020

Building on its success with the Glock Match Precision barrel, CMC recently introduced its new line of AR barrels. The first offering will be chambered in .223 Wylde for use with .223 Rem. and 5.56 NATO. 

The first barrel profiles will be available in the SOCOM variant and made from 4150 chrome-moly Vanadium and coated in H&M Blacknitride+ for increased wear resistance. The Blacknitride+ coating also improves fatigue strength, delivers better corrosion resistance, improved lubricity and enhanced cosmetic appeal.   

Likewise, barrels are available in differing gas lengths with M4 feed ramps, 1:7-inch twist rate, 1/2x28 thread pattern for standard muzzle devices, an 11-degree match crown for increased accuracy and a bottom dimple that makes it easy to install gas blocks.

CMC is able to accommodate the needs of everyone from civilian shooters to military and law enforcement thanks to precision engineering, instrument-inspected barrels, and air gauging to ensure the best in uniformity. Per CMC requirements, land and groove tolerance from breech to muzzle can vary only .0001 inches for the best concentricity.

Skills Check: Present Arms

We refer to the draw stroke as the presentation at Gunsite. It’s a better explanation than simply “drawing” the pistol, because it describes the act of presenting the pistol from the holster to the target or threat. In our “basic,” five-day pistol class we expect students to present the pistol and make hits on targets from 3 to 7 yards away in 1.5 seconds. Most students can do this in two or three days of training.
