CMMG 55B8D86-SG Dissent 5.56 NATO 10.5" Rifle

The CMMG 55B8D86-SG Dissent 5.56 NATO 10.5" rifle is a purpose-built modern sporting rifle engineered for operators who demand compact form factor without sacrificing combat effectiveness. Designed for close-quarters work, home defense, and tactical applications where maneuverability matters, this platform delivers professional-grade reliability in a package that weighs just 5.21 lbs and measures 31.4 inches overall. The short 10.5-inch barrel reduces velocity loss while maintaining 5.56 NATO ballistics in confined spaces—critical for law enforcement, military support roles, and civilian defensive use where workspace is limited.

CMMG's Dissent platform features a precision-machined receiver designed to tolerance exacting mil-spec standards, ensuring reliability across thousands of rounds. The 10.5-inch barrel strikes the optimal balance between velocity retention and overall length for vehicle and building entry scenarios—reducing sound signature and recoil energy while maintaining effective engagement distances to 300 meters. The rifle's compact profile minimizes operator fatigue during extended carry, critical for users conducting room-clearing, perimeter security, or emergency response where every ounce counts and every inch of length affects tactical positioning.

This configuration benefits law enforcement tactical teams, military personnel transitioning to civilian life, and responsible armed citizens preparing for home-defense scenarios. The SG designation indicates this rifle ships compliant with applicable federal and state regulations. Operators should verify local laws before purchase and engage a qualified armorer for any modifications; the platform accepts standard mil-spec components and is compatible with common modern sporting rifle accessories, optics mounts, and tactical furniture. Proper training and professional instruction are essential for safe and effective deployment in any role.
