Key Features

• Radial Delayed Blowback Action – Why it matters: This CMMG-exclusive system slows bolt opening, reducing recoil and port pop while keeping the action reliable with standard 9mm loads. You get a softer shooting, more controllable platform that cycles cleanly.
• Left Side Non-Reciprocating Charging Handle – Why it matters: Charging stays on your support hand side, and the handle doesn’t move with the bolt. This means you can clear malfunctions or reload without breaking your firing grip or losing your sight picture.
• 5.50″ M-LOK Handguard – Why it matters: The slim, free-floated design keeps weight forward minimal and gives you multiple M-LOK slots for mounting lights, lasers, or grips exactly where you need them.
• Picatinny Brace Adapter (1913 Rail End Cap) – Why it matters: You can attach your choice of pistol brace or stock (where legal) via the standard 1913 rail. This makes the Dissent adaptable to your preferred configuration without proprietary parts.
• Zeroed Drop-In Single Stage Trigger – Why it matters: A crisp, consistent break with minimal overtravel helps you shoot more accurately at speed. The drop-in design means no complex adjustments or gunsmithing required.

Who It’s For

This pistol is built for the shooter who wants a compact, reliable 9mm platform that runs on Glock mags and handles like a proper PDW. It’s ideal for home defense, truck gun duty, or range work where portability and accuracy matter more than barrel length. If you appreciate a well-engineered delayed-blowback action and prefer a side charger over a standard AR-15 charging handle, the Dissent MkGS is worth a close look.

Pros & Cons

• Pros: Radial delayed blowback reduces recoil and keeps the action clean; takes standard Glock 17/19 magazines; left-side charging handle stays out of the way; compact 10.5″ barrel with linear comp for better muzzle control; 33+1 round capacity gives you plenty of firepower.
• Cons: The 5.50″ handguard limits rail space for accessories compared to longer options; the radial delayed system is a bit more finicky with very light loads (though it runs flawlessly with standard 115-124 grain).

FAQ

Does this Dissent model accept standard AR-15 grips and stocks?

The lower receiver uses a standard AR-15 grip pattern, so you can swap grips easily. The rear end cap is a 1913 Picatinny rail for brace or stock attachment (check your local laws). It does not accept standard AR-15 buffer tubes directly.

What Glock magazines are compatible with the CMMG 99A806DAB?

It works with all double-stack Glock 9mm magazines, including G17 (17 rounds), G19 (15 rounds), and extended 33-round magazines. The included 33-round magazine gives you maximum capacity right away.

Is the radial delayed blowback system reliable with suppressed use?

Yes, the radial delayed action works well with suppressors because it reduces port pop and keeps the action timing consistent. Just be sure to use standard-pressure 9mm ammo (115-124 grain) for best reliability.

Can I install a different trigger in this Dissent?

Yes, it uses a standard AR-15 drop-in trigger group. The included Zeroed single-stage trigger is a good performer, but you can upgrade to a Geissele, Timney, or similar drop-in unit if you prefer a different feel.

What is the overall length with the brace adapter installed?

Without a brace or stock, the pistol measures about 20″ overall. Adding a standard pistol brace brings it to roughly 26-27″ total, depending on brace length.
