CMMG 60AB40CAB Dissent BR4 5.56 NATO 16.1" 11-Round Threaded Barrel Rifle

The CMMG 60AB40CAB Dissent BR4 5.56 NATO 16.1" 11-Round Threaded Barrel Rifle represents a purpose-built platform for tactical operators, competitive shooters, and civilian users seeking a California-compliant semi-automatic rifle with genuine performance credentials. This rifle bridges the gap between standard AR-15 ergonomics and state-mandated compliance, eliminating the need for featureless stocks or other restrictive modifications that compromise handling. Built on the proven Dissent BR4 platform, it delivers reliable 5.56 NATO chambering in a compact, balanced package suitable for both range work and duty-ready applications.

The 16.1-inch threaded barrel provides optimal velocity for 5.56 NATO while maintaining maneuverability in confined spaces—a critical consideration for home defense and vehicle operations. Threading at the muzzle allows mounting of suppressors, compensators, or flash hiders to tailor performance to specific mission requirements and noise signature. The 11-round magazine capacity adheres to California legal limits while maintaining single-stack feed reliability, ensuring consistent chambering without the malfunctions sometimes associated with compromised magazine designs. Weighing 12.2 pounds, the rifle balances controllability with firearm stability, reducing shooter fatigue during extended shooting sessions and improving accuracy potential through reduced muzzle rise and recoil impulse management.

Law enforcement agencies, tactical trainers, and California-resident shooters benefit most from this rifle's compliant-yet-capable design, eliminating legal ambiguity while preserving weapon functionality. The threaded barrel accommodates industry-standard muzzle devices rated for 5.56 NATO, ensuring compatibility with existing suppressor collections and tactical accessories without adapters or modifications. This rifle integrates seamlessly with standard AR-15 optic mounts, rail systems, and ergonomic controls, allowing shooters to leverage existing gear investments while meeting state regulatory requirements. Whether configured for duty, sport shooting, or home defense, the Dissent BR4 delivers the reliability expected from CMMG's track record in precision rifle manufacturing.
