CMC Barrels – After Glock comes AR-15

    Late in 2017 CMC Triggers (Yes, in Texas) released drop-in barrels for the Glock pistols. It is now time for CMC to introduce barrels for the AR15 platform. The CMC barrels are available in 7.5″, 10.5″ and 16.25″ and in .223 Wylde. In case you didn’t know, .223 Wylde is a chamber in which you can use both .223 Rem. and 5.56 NATO ammo.

    The CMC barrels are coated in H&M Blacknitride+ for increased wear resistance and are made from 4150 Chrome Moly Vanadium steel. According to CMC you can expect 1 MOA accuracy with these barrels.

     

    Below you can find the description of 16.25″ CMC barrel.

    Design is the perfect addition to your SBR or Pistol build! You do not want your SBR or Pistol barrel to be too light or too heavy, so the CMC Barrels is your solution!

    CMC’s 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.

    CMC incorporated input received from military, law enforcement and civilian shooters into the engineering of their AR15 barrels to accommodate modern-day shooting requirements. 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.

    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.

    Keep in mind that headspace, component selection, assembly methods, external variables such as the shooter, environmental conditions and ammunition will all have an impact on group sizes.

    CMC only recommends that you use factory new SAAMI approved ammunition in CMC Barrels. CMC stands behind their barrels performing 1 MOA (or better) when Match Grade ammo is used.

    CMC’s AR15 Barrels provide a 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.

    CMC AR15 barrels are then 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.

    I am sure everyone is thinking where are the 9×19, 300 BLK and 308 Win barrels? I guess it all depends on how many of these .223 Wylde barrels are sold.

    What do you think? Would you consider using these barrels for your next “pistol” or rifle build?
