Description

The CMMG 45A250F-AB DISSENT MkG .45 ACP 13rd 6.50″ 5.5″Proprietary Handguard 7075-T6 Aluminum CMMG Zeroed Grip is a no-nonsense AR pistol built for ranchers and rural workers who need stopping power in a compact package. Chambered in the classic .45 ACP, it brings the big bore to CMMG’s bufferless platform, ditching the buffer tube for a true PDW-sized frame that tucks into a truck cab or saddlebag without fuss.

Key Features

• Bufferless Design – WHY IT MATTERS: No buffer tube means a shorter overall length, making this pistol easy to stow in tight spaces like a work truck or ATV rack without losing reliability.
• Forward Non-Reciprocating Charging Handle – WHY IT MATTERS: You can charge the action without breaking your grip or coming off target, critical when you’re moving through brush or checking fence lines.
• M-LOK Handguard with Top Picatinny Rail – WHY IT MATTERS: Mount a light, laser, or grip exactly where you need it for low-light predator control or property security.
• Picatinny Rear End Plate – WHY IT MATTERS: Ready to accept sling mounts or a stabilizing brace right out of the box, no gunsmithing required.
• CMMG Zeroed Grip – WHY IT MATTERS: Ergonomic angle reduces wrist fatigue during extended use, and it’s textured to stay put even with wet or gloved hands.

Who It’s For

This pistol is for the working rancher who needs a reliable sidearm for dispatching varmints or defending livestock. It’s also a solid choice for rural property owners who want something more potent than 9mm but still compact enough for daily carry. If you spend more time on a tractor than at a range bench, this tool fits your life.

Pros/Cons

• Pros: Compact bufferless design, .45 ACP stopping power, Cerakote finish resists rust and wear, ambidextrous-friendly charging, easy to accessorize.
• Cons: Proprietary handguard limits aftermarket rail swaps; the 13-round magazine is smaller than some competitors’ offerings.

Comparison: DISSENT MkG vs. Zev Technologies OZ9 vs. Lone Wolf Distributors GTM-45

Feature	CMMG DISSENT MkG .45 ACP	Zev Technologies OZ9 (9mm)	Lone Wolf Distributors GTM-45 (Glock 21-based)
Caliber	.45 ACP	9mm	.45 ACP
Overall Length	~18.5″ (bufferless)	~19.5″ (with buffer)	~20″ (with buffer)
Weight	5.5 lbs	6.2 lbs	5.8 lbs
Handguard	Proprietary M-LOK	Proprietary M-LOK	Aftermarket compatible
Price	$2,067.01	$2,199.99	$1,899.99

The Zev OZ9 is a fine pistol, but it’s 9mm only and heavier. The Lone Wolf GTM-45 uses a Glock 21 frame, which adds bulk and a buffer tube. For pure .45 ACP power in the smallest package, the DISSENT MkG wins on portability and caliber.
