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.
The diameter is 1.115" and cannot be turned down. Overall length is 3.3".
