Description
The CMMG Dissent Mk4 complete upper assembly is chambered in 22 ARC and pairs with the CMMG Dissent Mk4 lower receiver (sold separately) to complete a compact, folding-stock semi-auto rifle. Its 16.10″ barrel with a 1:7 twist rate is built to stabilize a broad range of 22 ARC bullet weights for range and field use.
The DISSENT-pattern upper receiver is machined from 7075 T6 aluminum and paired with CMMG’s 15″ proprietary handguard in 6061-T6 aluminum. An adjustable 0.750″ gas block allows you to tune the direct impingement operating system for reliable cycling across varying loads and conditions.
This upper is sold without a lower receiver or magazine. Add a CMMG Dissent Mk4 lower to complete your build.
