Rifle, DISSENT, Br4, 300 BLK, 16.1", Non-Threaded
300 BLK has become one of the most popular .30 caliber cartridges on the market with a variety of supersonic and subsonic loadings optimized for hunting, target shooting, and self-defense. It was only fitting that the new Br4 Ranch Rifle included this caliber in one of it's (7) initial caliber offerings. We took a step back and acknowledged states like New York who restrict firearms with threaded barrels. Our newest entry of the Br4 with an all-new EMPIRE profile unthreaded barrel and a recessed barrel crown is also including 300 BLK in its initial offerings.
The 16.1" firearm ships with (2) 10rd magazines, Remington 870 stock compatible, cross-bolt safety, forward non-reciprocating side charger, a proprietary ZEROED single stage trigger, and your choice of (7) colors.
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.
