Picking the CMMG Dissent Br4 Rifle is easy, but choosing the right caliber to add to your safe will be a challenge. If you're leaning towards the tried and true 5.56mm, you won't do wrong with the 14.5" P&W Br4. Although the barrel is 14.5" the ZEROED SVD muzzle brake is pinned & welded to the muzzle, bringing the barrel's OAL to 16.1" which means no NFA tax stamp is needed as well as being in one of the best-looking rifles in its class.
The Rifle for Restricted States
Although just shy of being available to all 50 US states, the Br4 gives people in 2A unfriendly states a modern choice in a go-to carbine. Combining traditional controls and ergonomics together with modern engineering, there's a Br4 for every use case, from hunting, to self-defense, or sporting use.
Adjustable Gas Block
If you're looking to shoot suppressed or just fine tune your DISSENT to your preferred ammo, the adjustable gas block gives you the freedom to dial in the gas system exactly to your liking. Never too much and never too little.
