CMMG Dissent Br3 CA Compliant .308 Win - Grey - 2x 10 Rd - 16.1" - Rifle

The CMMG Dissent Br3 in .308 Winchester and Sniper Grey Cerakote brings the bufferless DISSENT platform to one of the world's most proven hunting and precision cartridges — a 16.1-inch semi-automatic .308 rifle with the Magpul SGA stock for traditional bolt-gun ergonomics, M-LOK handguard, full-length Picatinny rail, and reversible side charging handle in a compliance-friendly configuration. The Br3's Mk3 platform scales the DISSENT's bufferless operating system to the larger AR-10 frame required for the .308 cartridge without sacrificing any of the DISSENT line's defining features.

The CMMG Dissent Br3 is a semi-automatic rifle chambered in .308 Winchester, built on a billet 7075-T6 aluminum Br3 lower receiver and DISSENT 7075-T6 aluminum upper receiver in Sniper Grey Cerakote with a 16.1-inch 4140 chrome moly black nitride barrel and CMMG's bufferless compact action direct impingement operating system.

The bufferless operating system eliminates the buffer tube — the Magpul SGA Remington 870-pattern stock attaches directly to the receiver without a buffer tube in the stock, keeping the profile clean and the overall length to 38.2 inches. The DISSENT side charging handle is reversible for left- or right-hand use and forward-mounted for fast manipulation without breaking the sight picture or interfering with optics. The adjustable gas block allows fine-tuning for specific ammunition or suppressor use. The 16.1-inch barrel is threaded 5/8x24 for suppressor and muzzle device use, and the CMMG ZEROED muzzle brake is standard. The full-length Picatinny top rail on the upper receiver provides a stable, continuous optic mounting surface. The CMMG M-LOK handguard with M-LOK slots on all sides provides extensive accessory mounting options. The ZEROED drop-in single stage trigger delivers a crisp, consistent break. Two 10-round PMAG magazines are included. Backed by CMMG's Lifetime Quality Guarantee.
