"The CMMG Dissent Br47 Semi-Auto Rifle brings the 7.62x39mm cartridge into the modern age with traditional sporting-rifle modularity and bolt-gun ergonomics. It's built around a compact direct impingement action, similar to the AR, but with no need for a traditional buffer tube. The adjustable gas block gives you the freedom to fine-tune your Dissent to your preferred load never too much and never too little. It comes from the factory with the Magpul SGA stock with spacers for fit, but can easily be replaced with most Remington 870 stocks. The ZEROED single-stage trigger is incredibly smooth and crisp, and it resets quickly and predictably. The 4140 chrome moly barrel comes capped with CMMG's own dual-chamber brake to mitigate felt recoil, but will accept any 5/8""-24 muzzle device. The charging handle is easy to swap from right to left with no tools required. The full-length top Picatinny rail and M-LOK handguard provide ample space for optics and accessories. And the non-reciprocating reversible side charging handle allow for maximum control whether you're right- or left-handed. Includes two 10-round magazines.
