CMMG Dissent BR4 chambered in .223 Rem/5.56 NATO with a 14.5in pinned P&W CMMG Zeroed SVD brake, Magpul SGA stock, Zeroed single-stage trigger, and 10+1 capacity. Includes two Magpul 10rd PMAGs.
The CMMG Dissent BR4 is a compact AR-pattern rifle chambered in .223 Rem/5.56 NATO built around a 14.50 inches medium-taper threaded barrel and a P&W CMMG Zeroed SVD brake that is pinned and welded to achieve a legal overall length. This configuration yields a 16.1-inch effective barrel/compromise on muzzle devices while remaining one of the more practical short-barrel AR variants. The rifle ships with Magpul SGA stock, a Zeroed single-stage trigger, and two Magpul 10-round PMAGs. A reliable optic pairing under $1,000 is the Vortex Strike Eagle 1-6×24 for close-to-midrange work and fast target acquisition.

Its pinned and welded brake makes it a practical option where a shorter muzzle footprint is desired while maintaining legal overall length, and the Magpul SGA stock plus a single-stage trigger provide a familiar, straightforward interface for most AR users. Use it for range training, target work, or varmint/hunting applications where a shorter AR platform is appropriate.
