CMMG Dissent BR4 6mm ARC 16.1" - CA Compliant - AR-15 Rifle - 2x 10rd Mags - Coyote

The CMMG Dissent BR4 is a California-compliant semi-auto rifle chambered in 6mm ARC with a 16.1" barrel, cross-bolt safety, and Coyote Tan Cerakote receiver—a factory-configured compliant build for shooters who want 6mm ARC's long-range capability in a field-oriented color profile.

The 16.1" 4140CM SBN barrel with 1:7.5" twist delivers accurate, reliable 6mm ARC performance across the cartridge's broad bullet weight range. The CMMG Zeroed Muzzle Brake reduces muzzle rise for controlled follow-up shots at distance, and the Zeroed Drop-In Single Stage trigger provides a consistent, clean break. The 7075-T6 aluminum receiver finished in Coyote Tan Cerakote is paired with a Black Magpul SGA stock for adjustable fit and a contrasting two-tone appearance.

Cross-bolt safety satisfies CA featureless requirements at 16.1" OAL without requiring a pinned and welded muzzle device. Compatible with 6mm ARC magazines up to 10-round CA-legal capacity. Ships with two 10-round magazines. Thread pattern is 5/8"x24.

The Coyote Tan Cerakote receiver contrasts against the black barrel and Black Magpul SGA stock across the build, at 38.1" OAL and 8.0 lbs.

A practical option for California shooters who want a factory-compliant 6mm ARC rifle in Coyote Tan—whether for hunting, long-range range work, or any outdoor application where a non-black receiver is preferred.

CMMG extends the Dissent BR4 into 6mm ARC and multiple finishes to ensure compliant-state shooters have meaningful caliber and color options rather than a single default configuration.
