The RCB-KM solves excessive side blast/ concussion out of large port brakes. This controls the expanding gasses exiting the gun so that they can be used to aid in quicker follow up shots. This is accomplished by designing a port system that optimizes the available gasses without bringing about un-necessary turbulence/ concussive energy back to the shooter.

The result is an eloquent 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 13.7” and up. Check out the specs below and see why the Cobalt RCB is the solution that you have been waiting for.
