RIFLE DISSENT MK4 5.56MM 10.5IN NFA ARMOR BLACK

Small in stature but powerful in action, the 10.5” 5.56mm DISSENT® combines the capability of the AR15 without the additional bulk. Featuring our 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.

Available in a variety of custom Cerakote finish options; the rear of the DISSENT SBR features the DISSENT side folding stock with adjustable length of pull and adjustable cheek riser. A forward non-reciprocating charging handle allows for quick and easy manipulation without coming off target and the M-LOK handguard with top picatinny rail provides ample mounting space for whatever accessories you please.

Adjustable Gas Block

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.
