The CMMG Dissent BR4 chambered in 6mm ARC is engineered as a California-compliant AR rifle platform, developed for discerning shooters requiring consistent ballistic performance and practical utility. Its design prioritizes mitigating felt recoil, thereby facilitating sustained sight picture and promoting repeatable accuracy during extended engagements.
Key Features
6mm ARC Chambering
This platform is specifically optimized for the 6mm ARC cartridge, which provides a flat trajectory and consistent terminal performance. This attribute renders it suitable for both precision target acquisition and ethical hunting applications, contingent upon the selection of appropriate ammunition.
16.10-inch Barrel Configuration
A 16.10-inch barrel length is integrated to provide an optimal balance of projectile velocity retention and overall rifle maneuverability. This barrel specification is critical for operational efficiency across diverse field environments and competitive shooting scenarios.
Cerakote Aluminum Receiver System
The receiver system is constructed from aluminum and coated with Coyote Tan Cerakote. This finish provides robust corrosion resistance and an enhanced external durability, effectively shielding the rifle’s critical operating components from environmental degradation and wear.
Magpul SGA Stock Interface
Integration of the Magpul SGA stock ensures reliable ergonomic contact and a stable shooter interface. This configuration promotes consistent rifle handling characteristics and facilitates rapid target acquisition.
Zeroed Drop-In Single Stage Trigger
A Zeroed drop-in single stage trigger is factory-installed, delivering a crisp, predictable break. This design feature is instrumental in optimizing shot placement for critical engagements and enhancing shooter precision.
