The Crosstac Mk109 self-timing muzzle brake is based on Army science and research. Other brake designs use excessive weight to reduce recoil, or they are made to be a tacticool-looking muzzle ornament. Not the CrossTac Mk109! After reviewing the exhausting Army research into howitzer muzzle brake designs, CrossTac applied those primary efficiency concepts to the Mk109. The benefit for you is a brake that dramatically reduces recoil and has the added benefit of virtually eliminating muzzle climb. The muzzle brake design is fully caliber specific. The ports are sized to caliber, distance from the muzzle crown to each baffle varies and is based on caliber. You have to shoot this to believe it.
