The CMMG Dissent BR4 is a semi-automatic rifle built around a 16.10″ threaded nitride barrel chambered for .223 Rem/5.56 NATO. It pairs a midnight bronze Cerakote aluminum receiver and an M-LOK handguard with a Magpul fixed black polymer stock for durable, practical handling. An adjustable gas block lets you tune the gas system for suppressed or unsuppressed operation and to match specific loads. A mid-range optic such as the Vortex Strike Eagle 1-6×24 is a suitable choice under $1000 for this platform.
