Killer Innovation’s Killer B was specifically designed with long distance accuracy in mind. The unique port design reduces turbulence and asymmetric air flow patterns in front of and behind the bullet. The Killer B effectively reduces recoil and muzzle climb making it very easy for the shooter to spot impacts and significantly reduces follow-up shot times. We tuned the ports with multiple calibers over weeks of testing until we felt we had achieved the perfect balance of brake efficiency and accuracy on bullets diameters ranging from .223 – .308.  Whether you are a Military, LEO or a competition shooter, the Killer B will keep you on target.
