Key Features

• Bufferless Design — Eliminates the buffer tube, shortening overall length to PDW size while maintaining a full 6.50″ barrel. Why it matters: You get a compact package that still stabilizes .45 ACP rounds for accurate shooting.
• Forward Non-Reciprocating Charging Handle — Operates from the front of the handguard, staying stationary during firing. Why it matters: It keeps your support hand clear of the bolt, reduces snag risk, and allows easy charging with optics mounted.
• 5.5″ M-LOK Handguard with Top Picatinny Rail — Provides 12 positions for lights, lasers, or grips plus a continuous rail for optics. Why it matters: You can mount a red dot, flashlight, and foregrip without adapters.
• Threaded Barrel (6.50″) — Factory-threaded 5/8×24 for suppressors or compensators. Why it matters: Run suppressed without sending the barrel to a gunsmith.
• Glock Magazine Compatibility — Uses standard Glock 21 .45 ACP magazines, with two 13-round mags included. Why it matters: You can use common, affordable mags you likely already own.

Who It’s For

This pistol fits shooters who want a compact .45 ACP platform that bridges the gap between a handgun and a PDW. It’s for home defense, truck gun roles, or anyone who needs a powerful caliber in a short, packable frame without sacrificing rail space for accessories. It also appeals to suppressors owners who want a dedicated .45 host.

Pros & Cons

Pros: Bufferless design allows folding stock conversion (with tax stamp); threaded barrel ready for suppressors; Glock mag compatibility; light weight at 4.90 lbs; full-length 6.50″ barrel gives better velocity than typical 5″ .45 pistols.

Cons: Non-reciprocating charging handle requires a learning curve for manual cycling; price point ($1,874.72) is higher than many .45 ACP pistols; limited aftermarket support compared to AR-15 platforms.

Compared to the Zev OZ9C and Agency Arms AOS, the CMMG Dissent MKG offers a longer barrel, bufferless platform, and M-LOK handguard for mounting accessories. It’s heavier but more versatile for PDW use. The Zev and Agency are lighter for carry, but lack the rail space and suppressor-ready barrel.

FAQ

Is the CMMG Dissent MKG .45 ACP accurate at 25 yards?

Yes. The 6.50″ threaded barrel provides a longer sight radius and better velocity than typical .45 pistols. With quality ammunition, expect 2-3 inch groups at 25 yards from a rest.

Can I convert this to a rifle with a stock?

Yes. The bufferless design allows adding a stock with a Picatinny adapter, but requires a tax stamp as an SBR. The rear end plate is Picatinny-ready for folding stocks.

Does it come with a case or tools?

No case or tools are included. It ships with two 13-round Glock 21 magazines and a cable lock.

Is the barrel threaded for standard suppressors?

Yes. The 6.50″ barrel is threaded 5/8×24, compatible with most .45 ACP suppressors like the SilencerCo Osprey 45 or Dead Air Ghost 45.

What is the warranty?

CMMG offers a limited lifetime warranty on manufacturing defects. Per CMMG specs, the warranty covers the original owner only.
