RCB-HX-HT Details

The RCB (Reduced Concussion Break) family of muzzle devices offers the BEST muzzle brake durability and performance for your rifle.

Purpose-built for extreme strength and longevity with 17-4 Stainless, AND heat treated for extreme resistance to corrosion/erosion, the RCB family of muzzle devices offers the BEST muzzle brake durability and performance for your rifle.

The RCB family is Cobalt Kinetics’ solution to excessive side blast/ concussion out of large port brakes. Our approach was a simple one, to control the expanding gasses exiting the gun so that they can be used to aid in quicker follow-up shots. We accomplished this by designing a port system that optimizes the available gasses without bringing about unnecessary turbulence/ concussive energy back to the shooter.

The result is a solution that; controls muzzle climb, helps improve split times on follow-up shots, and kills excessive muzzle flash. The finest attention to detail was also paid to the material selection, coatings, and tolerances on these units to provide the best possible option for your recoil mitigation needs.

The RCB’s can also be pin/ welded to allow for a 16” OAL on barrels ranging from 14.5” and up. Check out the specs below and see why the Cobalt RCB is the solution that you have been waiting for.

The RCB-HX models are available in 1/2X28 tpi. They will support any suppressor that uses a HUXWRX “QD” (quick disconnect) adapter.

**Shims Not Included**
HUXWRX QD is a licensed feature from HUXWRX Suppressors.
