Designed in cooperation with Blitzkrieg Components, the RB5007 reduces felt recoil by 30%, improving the shooters overall accuracy and eliminating muzzle flip. The test data shows that the time to reacquire a target decreases, and in most cases the shooter will not have to leave their scope after taking their shot. The RB5007 works in PCC builds with 3.5" - 7.5" barrel unsuppressed and will work with all common 9mm loads. The RB5007's weight and length have been optimized for the 9mm application so that it runs reliably, softens recoil, and stops just behind the bolt catch.
