CMMG 12.5″ .308 Upper Group, MK3 DISSENT

CMMG 12.5″ .308 Upper Group, MK3 DISSENT

For those building on the .308 caliber, the shorter barrel length may not have the long range performance but makes up for it in maneuverability and storage.

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 ARs. The forward non-reciprocating side charger allows for quick bolt operation without coming off target.

All DISSENT Upper groups include a 1913 Picatinny rail end plate to use in place of the lower receiver buffer tube. Upper groups are available in your choice from seven Cerakote finish options.

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.

Lifetime Quality Guarantee

We aim to please, that’s why every CMMG product is backed by our Lifetime Quality Guarantee against material and workmanship defects.

Mk3 DISSENT upper groups are designed to work with CMMG Mk3 (DPMS LR308 Gen-1 Pattern) lower receivers. Due to design differences, other manufacturers’ LR308 lowers may work but CMMG can only guarantee proper fit and function with Mk3 lower receivers.
