Our advanced geometry muzzle brakes are designed to be highly effective in eliminating felt recoil and muzzle rise for quicker, more precise follow-up shots. Advanced geometry also minimizes flash signature. Made of extremely strong aluminum and hardcoat anodized for superior durability, heat and corrosion resistance. Professional workmanship guarantees perfect concentricity for maximum accuracy.

Large directional ports on the top direct exhaust gases diagonally backwards to compensate for recoil and muzzle rise. The brake is designed to minimize dust printing when shooting prone. As a bonus, the aggressive looks of the brake gives your rifle that extra touch.
 
The brake is designed to look equally good on all diameter barrels. Suitable for bullet diameters up to 10.0 mm, most effective starting from 9.0 mm. To maintain its durability, modifying it to accommodate larger diameter bullets is not recommended.
 
Crush washer included.
