Product Description

The CMMG DISSENT MK4 upper group in .22 ARC (Advanced Rifle Cartridge) is built to deliver consistent function and strong ballistic performance from the AR-15 platform. This complete upper is engineered around CMMG’s compact direct-impingement action, housing the recoil assembly within the upper to reduce overall bulk and eliminate the need for a traditional buffer tube. It features a forward, non-reciprocating side charging system for fast manipulation, an M-LOK handguard for accessory mounting, and an adjustable gas block for tuning reliability and suppressor use. Finished in Sniper Gray, it’s designed to pair with Mil-Spec compatible lower receivers and includes a 1913 Picatinny rear end plate for flexible stock/brace and sling solutions.
