We aim to please, that's why every CMMG product is backed by our Lifetime Quality Guarantee against material and workmanship defects. Those looking for the full power cartridge equivalent of the AR15 often turn to the large frame AR10s like CMMGs Mk3 platform, based on the popular DPMS Gen 1 High Pattern design. Like the AR15 though, the Mk3and other AR10 sized rifles face the same scrutiny and arbitrary regulations in too many states and locales, barring people from modern rifles better suited for hunting, self-defense, and sporting use. CMMG is bringing the same philosophy as the Br4 to our own large frame lineup with the DISSENT Br3.The new DISSENT Br3 brings three calibers at launch with the same traditional ergonomics and furniture compatibility as the Br4. Two caliber favorites include .308 Win and 6.5 Creedmoor along with the newcomer, 8.6BLK. Much like the Br4 being compatible with DISSENT Mk4 upper groups, the Br3 lower is compatible with all DISSENT Mk3 upper receivers. Traditional options include the cross-bolt safety and Magpul SGA 870 pattern stock while modern upgrades include M-LOK slots for lightweight accessory attachment, Ambi mag releases, a reversible and non-reciprocating forward side charger, and more. All DISSENT Br4 rifles will ship with two 10 round magazines
