This is the brake that started it all for us. We set out to design a muzzle brake that would actually tame the 338 Lapua. This brake is meant for Larger barrels that are generally required by the 338 Lapua.
All of the Gen 1 require installation by a competent gunsmith. By properly fitting this brake you can achieve a perfect seamless fit on your rifle as well as perfect coaxial bore alignment. Please see the video for further information.
The diameter is 1.115" and cannot be turned down. Overall length is 3.3".
