CMMG DISSENT MK17 | 9mm | 16.1 Barrel

The CMMG DISSENT Mk17 is a 9mm PCC built on a Mk17 platform that accepts common Sig P320/M17/M18 magazines. It features a 16.1″ barrel, side-folding stock with adjustable length of pull and cheek riser, and an M-LOK handguard with a continuous top rail for accessory mounting. For a practical optic under $1,000 that pairs well with this platform, consider a 1-6×24 variable such as the Vortex Strike Eagle 1-6×24 for fast close work and usable low-power magnification for mid-range shots.

Common applications for this rifle include target/range training and practical PCC competition where magazine compatibility and low recoil are advantages.
