The CMMG Dissent BR3 Rifle (CMMG part no. 38A530CAB) is chambered in .308 Winchester, also compatible with 7.62 NATO ammunition, and finished in Armory Black for a clean, purpose-built look. It’s built around a 16.1-inch barrel with a 1:10 twist rate that stabilizes common .308 bullet weights, and it uses a crossbolt safety rather than a standard AR selector for a distinct manual of arms. It ships with a 10-round magazine, for 11 rounds total with one chambered, and runs as a semi-automatic action for reliable follow-up shots. This build is a solid, compact option for a .308 range rifle or home-defense gun.
