CMMG Dissent MK4 9mm Pistol, 6.50" Barrel, 33-Round, Black Armor Cerakote - Model 94A6867AB

The CMMG Dissent MK4 9mm pistol brings AR-platform modularity and familiarity to a compact 9mm package that handles like an extension of your rifle inventory. Built on the proven Mk4 platform, this 6.50" barrel 9mm pistol fires from a compact-action radial delayed blowback system, delivering reliable performance in a package that tips the scales at just 4.6 lbs. Whether you're looking for a dedicated 9mm trainer, a fun range gun, or a truck gun, the Dissent MK4 punches above its weight class thanks to its thoughtful ergonomics and accessible controls.

What sets the Dissent apart is its use of standard CMMG 9mm AR conversion magazines—the same profile as 5.56mm mags—so manually of arms is familiar if you already shoot AR carbines. The double-stack feed geometry means faster, easier loading compared to single-stack platforms. The gun ships with two 30-round magazines (note: product listing references a 33-round capacity; verify current magazine inventory). A side-charging handle keeps your grip on target and speeds up manipulations, while the M-LOK handguard gives you clean, modern mounting for red dots, lasers, lights, or whatever else your setup demands. The muzzle wears a CMMG ZEROED linear compensator (1/2 x 28 threads) to tame recoil and keep your sight picture steady.

Build quality reflects CMMG's attention to detail: 7075 T6 aluminum upper and lower receivers, a 4140CM barrel with a 1:10 twist, a TriggerTech AR-D 2-stage trigger, and Black Armor Cerakote finish that shrugs off hard use. The 1913 Picatinny rail end cap opens the door to sling attachments, and the CMMG ZEROED 60/90-degree safety selector gives you fine control. At 14.7" overall length, it's nimble enough for vehicles, home defense roles, or wherever a compact 9mm makes sense. This is a shooter's pistol—not marketing fluff, just solid engineering in a form factor that rewards familiarity.

Frequently Asked Questions

What magazines does the CMMG Dissent MK4 9mm use?

The Dissent MK4 fires from CMMG 9mm AR conversion magazines. These mags share the profile of standard 5.56mm AR magazines, so the manual of arms feels familiar if you shoot the AR platform. They feed from a true double-stack geometry and ship with two 30-round magazines.

Can I attach a brace or stock to the Dissent MK4?

Yes. The rear receiver end cap is a 1913 Picatinny rail that accommodates sling attachments, braces, or stocks (subject to local and federal regulations; verify your jurisdiction's rules before purchase or modification).

Is the side charger on the left or right side?

The DISSENT side charger is located on the left side of the receiver, allowing right-handed shooters to charge the gun without breaking their grip.

What accessories can I mount on the handguard?

The 5.5" proprietary handguard features M-LOK slots for mounting modern accessories such as optics, lasers, lights, and vertical grips. The muzzle compensator has 1/2 x 28 threads for sound suppressors or other muzzle devices rated for that thread pattern.
