The CMMG Dissent MK17 9mm tactical rifle brings practical versatility to the pistol caliber carbine platform. Built on CMMG's proven Mk17 system, this 16.1-inch barreled PCC operates on a compact action-radial delayed blowback system and feeds from standard Sig Sauer P320/M17/M18 magazines—meaning you're not locked into proprietary ammo supply if you already run Sig pistols. The result is a lightweight, maneuverable rifle that handles like an AR-15 but costs considerably less to shoot, making it ideal for plinking, home defense, or introducing shooters to rifle fundamentals without the recoil or noise of centerfire rounds.
The Dissent side-folding stock with adjustable length of pull and cheek riser lets you dial in comfort and handling, whether you're running it in cramped quarters or from a bench. The forward non-reciprocating charging handle won't interfere with your optic or accessories, and the 15-inch proprietary M-LOK handguard with integrated top picatinny rail gives you real estate to mount lights, lasers, or glass. The 4140CM barrel wears a 1:10 twist and threads at 1/2x28 for the included CMMG ZEROED muzzle brake, which works with the ZEROED trigger, grip, and safety to deliver a cohesive, tuned platform out of the box.
At 6.7 pounds and fully collapsible to 25.9 inches, the Dissent fits vehicle racks, backpacks, and truck beds without the footprint of a full-length rifle. Cerakote-finished in Armor Black, it's dressed for duty while the aluminum receivers (7075 T6) keep weight down. Two 21-round Sig P320 magazines ship with the rifle, so you've got capacity and compatibility to match your pistol collection.
