CMMG 38A260C-SG Dissent BR3 .308 Win 16.1" 10-Round Rifle

The CMMG 38A260C-SG Dissent BR3 .308 Win 10-round 16.10" 7075-T6 Aluminum Receiver Sniper Gray platform represents CMMG's approach to sidestepping arbitrary state-level regulations that restrict modern rifle designs. Built on the same compatibility philosophy as the BR4, the Dissent BR3 lower receiver accepts all CMMG Dissent MK3 upper receivers, giving operators a modular platform optimized for hunting, defensive applications, and precision shooting without the configurational restrictions facing traditional AR10-pattern rifles.

The BR3 lower is machined from 7075-T6 aluminum, a military-grade alloy favored for its strength-to-weight ratio and dimensional stability under sustained use. At 12.8 lbs total, this .308 Winchester platform delivers manageable weight for extended field work while maintaining the mass needed for recoil mitigation in a centerfire caliber. The 16.10-inch barrel length balances velocity development in .308 Win with practical handling in operational and hunting scenarios. M-LOK mounting slots along the receiver allow for modular accessory integration without the weight or complexity of full Picatinny rails, giving users flexibility to configure optics, lights, and grips according to mission requirements.

This rifle suits operators and hunters seeking a .308 Winchester platform that bypasses design-based legal scrutiny in restrictive jurisdictions. The BR3's modular upper/lower interface means users can swap Dissent MK3 uppers to adapt caliber or configuration without purchasing a complete new rifle. The sniper gray finish provides a neutral appearance suitable for both tactical and outdoor applications. Ten-round capacity complies with magazine restrictions in multiple states while maintaining practical magazine changes during range training or field use.
