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 any aftermarket 870 stock the buyer prefers. CMMG's Zeroed SVD muzzle brake is pinned and welded to keep the rifle inside the feature-test envelope without crossing into NFA short-barrel territory.

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 Compact Action lower, which accepts 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 the standard AR upper experience (any handguard, any optic mount, any trigger) 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 a pinned-and-welded muzzle device, an adjustable gas block, and the CMMG quality control.
