The CMMG Dissent BR4 in .350 Legend is a modern straight-wall hunting rifle built for hunters in states requiring that cartridge class. Winchester developed the .350 Legend in 2019 to deliver power that rivals the .30-30 and .243 Winchester while keeping recoil more manageable than many other straight-wall options—a real advantage if you're hunting long days or shooting from uncomfortable positions. This rifle pairs proven .350 Legend ballistics with CMMG's refined engineering and thoughtful ergonomics, giving you a serious hunting tool that doesn't feel like a compromise.
The BR4 platform uses a compact direct impingement system with a carbine-length gas port, feeding reliability without excess complexity. Its 16.1-inch barrel with 1:16 twist rate is cut from 4140CM steel and treated with a durable Cerakote finish that handles field conditions. The upper and lower receivers are precision-machined from 7075 T6 aluminum billet—the kind of solid construction you expect from CMMG. At 7.7 pounds and 38.1 inches overall, it's nimble enough for stand hunting or glassing open country without wearing you down.
The ergonomics lean practical: a Dissent side-charging handle (reversible for left or right-hand operation), a CMMG ZEROED drop-in trigger, a reversible cross-bolt safety, and a Magpul SGA stock—the shotgun-pattern grip is comfortable and keeps the rifle handy. The 15-inch proprietary CMMG handguard gives you room for accessories without unnecessary bulk. You get two 10-round magazines to start, and the 1/2x28 muzzle threads on the CMMG ZEROED brake mean you can add a suppressor or muzzle device to suit your setup.
If you hunt in a straight-wall state and want a rifle that respects both the cartridge's strengths and your shoulder, the Dissent BR4 is worth a serious look.
