Crosstac Mk109 5.56/223 Muzzle Brake

Crosstac Mk109 5.56/223 Muzzle Brake - The Crosstac Mk109 Muzzle BrakeTM is a self-timing design based on science and engineering research into both port sizes and distances from the muzzle crown. It changes size and location mathematically by caliber. Other brake designs use excessive weight to reduce recoil, or they are made to simply be a tacticool-looking muzzle ornament. Their brakes are designed to function at a high efficiency level using scientifically engineered port timing from military research and development. The benefit for you is a brake that dramatically reduces recoil and has the added benefit of dramatically eliminating muzzle climb using gas pressure, not weight. The benefit of a lighter weight is less point of impact shift vs a bare crown, and reduced changes in the natural barrel harmonics. Their brakes weigh in at ounces, not pounds. Hardened 17-4 stainless lasts for thousands of rounds. Self-timing benefits you by the ability to clock the brake at an angle if you so desire. Installation is simple, please see the video. Do not over-torque, simply hand tighten, snug it a little further, and it will not shoot loose. 17-4 Stainless Steel, Hardened (This Is Tough Stuff And Will Last A Long Time) Black Oxide Coated Class 3 Threads (Tight For Minimal Slop)
