Taking its design from artillery brakes, this unit uses two large impingement baffles in an open form construction to achieve probably the best recoil reduction of the.50 beowulf brakes at subjectively 40% to 50%.Blast is directed sideways from the two opposite facing ports on each side.The unit is symmetrical in operation and does not provide reduction of muzzle jump.Back-blast to the shooter is negligible, but there is a noticeable blast to either side of the weapon.Model: TankMaterial: SteelThread Pattern: 49/64-20 tpi
