The BR4 rifle configuration uses CMMG's bufferless Compact Action, placing dual guide rods inside the upper receiver. This design removes the need for a traditional buffer tube while retaining AR-15 pattern controls. The forward, non-reciprocating side-charging handle offers easy access without interfering with operation.
Chambered in .350 Legend, the rifle carries a 16.1 in barrel with a threaded muzzle and a clear caliber marking on the barrel. The listed capacity is 20+1, and the package includes both 20-round and 10-round magazines to match different range or hunting needs.
Its free-float aluminum handguard features M-LOK slots for accessories, and a continuous 12 o'clock Picatinny rail runs across the receiver and handguard. An M-LOK-mounted bipod arrives installed for immediate bench or prone support.
The aluminum receiver and handguard wear a tan finish, contrasted by a black fixed polymer stock. The stock shows Magpul branding with molded text "SGA 870" and provides a 12.5 in length of pull. Overall, the configuration delivers a clean, modern AR-platform layout in the DISSENT series.
