From the manufacturer
CMMG DISSENT Mk4 5.56x45mm NATO 10.5in Upper Receiver 1-7 Twist .750in 1/2 X 28 TPI Tungsten. 5 DISSENT 5.56 is a ton of fun and its rowdy Now that we got that out of our system our ears quit ringing and we arent seeing fireballs anymore we are able to bring the same patent pending compact action to even more people with the arrival of the 10.5 DISSENT. A longer barrel will give improved ballistics while the DISSENTs compact platform still keeps this as a small but powerful pistol to fill your needs. Its no secret that pistol stabilizing braces have been a target for scrutiny over the years and those that enjoy building their own AR pistols have wondered what will come out of all the uncertainty. DISSENT is our answer. Utilizing our patent pending direct impingement Compact Action DISSENT upper groups house the entire action and recoil assembly in the upper receiver resulting in less bulk and length than traditional AR pistols. The forward non-reciprocating side charger allows for quick bolt operation without coming off target. DISSENT Upper groups include a 1913 Picatinny rail end plate to use in place of the lower receiver buffer tube.
