Cmmg Dissent Mkg 45Acp 16.1 Armor Black

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.

Frequently Asked Questions

What magazines does the CMMG Dissent MkG .45 ACP use?

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.

Is the Dissent MkG carbine easy to carry and store?

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.

What makes the bufferless operation different from a standard AR-pattern PCC?

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.

Is the charging handle ambidextrous?

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.

Can I add optics and lights to this rifle?

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.
