CMMG Dissent Mk4 Pistol, 9mm, 6.5-Inch, Black

The CMMG Dissent Mk4 (CMMG part no. 94A6867AB) brings 9mm to CMMG’s buffer-tube-free Dissent platform, giving shooters a genuinely compact pistol-caliber AR. It runs CMMG 9 AR Conversion magazines, which share the same profile as standard 5.56mm magazines for a familiar manual of arms and true double-stack feeding from top to bottom. Bolt operation is handled through a forward non-reciprocating side charger, letting you stay on target while cycling the action. The M-LOK handguard keeps accessory mounting clean, while the rear 1913 Picatinny rail end plate accepts the sling, pistol brace, or stock configuration you build toward. Finished in black by CMMG, this 6.5-inch 9mm Dissent is one of the most compact pistol-caliber ARs on the market.
