Small in stature but powerful in action, the 10.5" 5.56mm DISSENT combines the capability of the AR15 without the additional bulk. Featuring CMMG's patent-pending direct impingement Compact Action, the DISSENT houses the entire action and recoil system in the upper receiver, eliminating the need for the buffer system entirely. If you're looking to shoot suppressed or just fine tune your DISSENT to your preferred ammo, the adjustable gas block gives you the freedom to dial in the gas system exactly to your liking. Never too much and never too little. TriggerTech's AR-D trigger was developed in collaboration with CMMG to be fully optimized for use with DISSENT firearms and upper receiver groups. With a 4 lb pull weight, the AR-D trigger showcases a light, repeatable break.
