CMMG 30BC239AB Dissent MK4 300 Blackout 10.50", Left Side Charging Handle, Armor Black, Zeroed Linear Comp, 9.60" M-LOK Handguard, Picatinny End Plate, Fits AR-Platform

Many of you have fallen in love with the 6.50 inches .300 AAC Blackout DISSENT, so we've decided to push the boundaries even further, introducing the all-new 10.50 inches .300 AAC Blackout DISSENT upper group. This upgraded length not only enhances ballistics but also caters to those seeking a more suppressor-friendly configuration for their .300 AAC Blackout AR pistol builds. In response to ongoing scrutiny surrounding pistol stabilizing braces, DISSENT represents our innovative solution. Featuring our patent-pending direct impingement Compact Action, DISSENT upper groups integrate the entire action and recoil assembly within the upper receiver. This design reduces bulk and overall length compared to traditional AR pistols.

The forward non-reciprocating side charger ensures quick bolt operation without losing sight of your target. Each DISSENT Upper Group includes a 1913 picatinny rail end plate, offering versatility by replacing the lower receiver buffer tube. The 300 BLK cartridge is renowned for its adaptability, with specific loadings tailored for suppressed use. With an adjustable gas block on every .300 AAC Blackout DISSENT, you can fine-tune the gas system to optimize performance with your preferred supersonic or subsonic ammo.

DISSENT upper groups house the entire action and recoil assembly in the upper receiver resulting in less bulk and length than traditional AR pistols. The forward non-reciprocating side charger allows for quick bolt operation without coming off target.
