CMMG
The CMMG Dissent MkG .45 ACP is a modern take on a time-tested round, bringing the soft-shooting ballistics of .45 ACP into a compact PCC (pistol caliber carbine) that handles like nothing else on the market. Built on CMMG's proprietary MkG platform, this 16.1-inch carbine uses a radial delayed blowback action and bufferless operation—no heavy bolt carrier group pounding away, no buffer tube eating up real estate. If you've run a .45 ACP in a handgun and wished for easier follow-ups and flatter shooting from a longer sight radius, this is exactly that gun.
The Dissent MkG splits the difference between a traditional rifle and a pistol-caliber fun gun. At 6.7 pounds and folding down to 25.9 inches, it's compact enough for truck storage and truck-gun duty, but the 16.1-inch barrel and proper sight plane make it genuinely shootable at distance. The side-folding stock means you don't sacrifice ergonomics for portability. A reversible side charger keeps your support hand's thumb out of the firing path, and the DISSERT-branded ZEROED trigger is clean and predictable—the kind of unit you want when you're putting rounds downrange in volume.
Build quality is solid: forged aluminum upper and lower receivers in 7075-T6, a 4140CM barrel, Cerakote in Armor Black, and M-LOK handguard real estate for the optics and lights you actually want. The package ships with two Glock 13-round magazines, so you're ready to run. For shooters who want the ballistic mildness and cost-per-round efficiency of .45 ACP without the pistol-length sight radius or the recoil-management headaches of a rifle caliber, the Dissent MkG is a thoughtful build that doesn't try to be something it's not.

| Magazines Included | Two Glock-Pattern 13-Round |
| Weight | 6.7 lbs |
| Length (Extended) | 35.5 inches |
| Length (Folded) | 25.9 inches |
The rifle is compatible with Glock-pattern magazines and ships with two 13-round magazines. This makes feeding inexpensive and straightforward—any standard Glock .45 ACP mag will work.
Yes. At 6.7 pounds with a side-folding stock that collapses to 25.9 inches, it's built for portability. Folded, it fits easily in a backpack, behind a truck seat, or a car safe without taking up much space.
The radial delayed blowback action cycles without a heavy bolt carrier or buffer tube, which reduces recoil impulse and noise signature compared to direct blowback designs. It's a smoother, softer shooting experience—especially noticeable in .45 ACP.
The DISSENT side charger is reversible, meaning you can move it to either side of the receiver to suit your preference or support-hand technique. This keeps your thumb clear of the charging path no matter which way you configure it.
Yes. The 15-inch M-LOK handguard provides plenty of space for mounting optics (via a picatinny riser or direct-fit mount on the receiver) and tactical lights or other accessories where you need them.
