Design and Bufferless Receiver

The DISSENT BR4 leverages CMMG’s patented bufferless receiver and the Compact Action system to provide reliable direct impingement operation without a traditional buffer tube assembly. This allows the rifle to accept conventional rifle-style stocks while keeping the receiver profile compact. The absence of a buffer tube opens up stock choices and handling options for shooters who prefer a classic rifle cheek weld and balance.

Caliber: .338 ARC — Purpose and Performance

The chambering in Hornady’s new .338 ARC gives the platform substantial terminal energy compared to smaller AR-large-bore rounds. .338 ARC is designed to replicate the suppressed/subsonic versatility shooters know from .300 BLK while delivering more energy on target and reduced need for gas-system retuning when switching between suppressed and unsuppressed setups. This makes the rifle a strong choice for medium-game hunters and long-range tactical applications where one-gun versatility matters.

Barrel, Finish, and Included Components

This model features a 16.1-inch barrel and a Coyote Tan Cerakote finish that holds up to field wear. CMMG ships the rifle with a Magpul SGA stock for 870 shotguns adapted on this platform, and a single 10-round magazine is included, giving you basic readiness out of the box. The combination of a shorter barrel and .338 ARC balances maneuverability with ballistics appropriate for extended reach shots.
