The CMMG DISSENT Mk17 is a purpose-built 9mm AR-style pistol platform that pairs a compact 6.5 barrel profile with a side-charging bolt and CMMG accessories for practical, range-focused use. It ships configured for Sig P320 magazine compatibility and features a left-side non-reciprocating charger, a TriggerTech AR-D two-stage trigger, and a CMMG ZEROED linear compensator on a 1/2 x 28 threaded muzzle. For a sighting solution under $1,000, a compact red-dot such as a Trijicon MRO or a similar mid-size optic will provide fast target acquisition without adding excessive bulk.
This configuration is well suited to pistol-caliber carbine (PCC) style range shooting and competitive PCC matches where magazine compatibility and controllable recoil are priorities. Its compact footprint also supports use as a maneuverable range/training platform.
