Product Description
The CMMG DISSENT upper group in .22 ARC (Advanced Rifle Cartridge) is built for shooters who want a compact, modern AR-15–compatible upper with premium features for tuning and adaptability. Designed around CMMG’s direct-impingement Compact Action, the recoil system is contained within the upper receiver—eliminating the need for a traditional buffer tube and helping create a shorter, cleaner overall package. It features a forward, non-reciprocating side charging handle, an optics-ready top Picatinny rail, and an M-LOK handguard for flexible accessory mounting. An included 1913 Picatinny rear end plate makes it easy to configure with compatible stocks or accessories, while the adjustable gas block helps dial in performance for your ammunition and suppressor setup.
