CMMG DISSENT BR4 16.1-Inch Barrel .300 Blackout Midnight Bronze Rifle

Description

Product Overview

The CMMG DISSENT BR4 is a compact-action .300 Blackout rifle built for flexible use with both subsonic and supersonic ammunition. Its 16.1-inch salt bath nitride finished 4140 CMV barrel uses a 1:7 twist and a 5/8x24 threaded muzzle, while the adjustable carbine-length gas system lets shooters tune operation for different loads and suppressor use. The rifle combines a 7075-T6 aluminum receiver set with a 15-inch M-LOK handguard, full-length top Picatinny rail, reversible side charging handle, Magpul SGA stock, and CMMG Zeroed single-stage trigger. Its Midnight Bronze Cerakote finish adds corrosion resistance and a distinctive appearance.
