CMMG Dissent BR4 16.1" 5.56

CMMG's Dissent BR4 is the company's purpose-built answer to PICA and the California feature test. The Compact Action lower omits the AR pistol grip and the collapsing AR-style stock in favor of a Remington 870 shotgun-pattern stock interface, which means it accepts the Magpul SGA 870 stock shipped from the factory plus other compatible 870-pattern stock options. CMMG's Dissent system eliminates the traditional AR buffer tube while keeping an AR-pattern accessory and fire-control path.

The 16.1-inch 4140CM barrel runs a 1:7 twist with salt-bath nitride finish and a 0.750-inch adjustable gas block from the factory. Standard STANAG magazines feed through the proprietary Compact Action lower, which supports standard AR-15 fire-control groups. The rifle is sold to Illinois and Massachusetts residents through local dealers; CMMG ships direct in 47 states.

This is the right pick for AR-15 buyers who want AR-pattern optics, handguards, and trigger compatibility but cannot run a pistol grip in their home state. The price premium vs the FightLite SCR or Foxtrot Mike Ranch Rifle is the cost of the Compact Action system, an adjustable gas block, and CMMG quality control.
