DETAILS:
Compact 9mm PCC Performance
Pistol caliber carbines and PDWs have become quite popular recently. They are great for personal defense and offer a much more cost-effective alternative to rifles when it comes to recreational shooting at the range. If you want to build a reliable, modern AR-style 9mm carbine, you should check out CMMG's complete upper assemblies. This CMMG Dissent 9mm upper comes with a 10.5-inch short-barreled upper and a complete side-charging setup.
Unmatched Shooting Experience
Crafted from resilient 4140 Chrome Moly Steel, the barrel offers enhanced corrosion resistance and strong heat dissipation. The barrel is extremely durable and, with its 1:10-inch-per-inch rifling, is designed to be accurate as well. The barrel on this upper assembly is threaded with a standard 1/2"-28 thread pitch, and it comes equipped with the CMMG 9mm ZEROED Linear Compensator, which helps with recoil mitigation and decreases muzzle rise for a smoother shooting experience.
Moving on, this upper assembly comes with a 9.6-inch modular handguard. This proprietary handguard from CMMG has a lightweight yet durable aluminum construction and features M-LOK slots on both sides, with a continuous Picatinny rail on top. That gives this 9mm side charging upper room for compatible sights, accessories, and the support-hand placement you prefer.
Compact and Feature-Packed
One standout characteristic of this upper assembly is its compact action, cleverly designed to accommodate the recoil spring within the receiver itself. This configuration eliminates the need for a buffer tube altogether. Additionally, this upper assembly features a side charging handle instead of the traditional rear charging handle common on AR-style rifles, improving ergonomics and the shooting experience.
This CMMG Dissent 9mm upper also includes the Dissent Side Charging Bolt, which, along with other components, has been HPT- and MPI-tested to support quality and durability. For builders comparing upper assemblies, this setup offers a compact operating system, a left-side charging handle, and CMMG’s complete upper configuration in one package.
