Upper Group, DISSENT, Mk47, 7.62x39mm 12.5"
Supplement your barrel length options or kick off a new build with the bufferless 7.62x39mm DISSENT upper group with the 12.5" barrel. Built off the mid-size Mk47 platform, this DISSENT upper requires no buffer tube.
Available in a variety of custom Cerakote finish options or hard coat anodized; DISSENT upper groups include a picatinny rear end plate for your existing Mk47 lower. 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.
