Installation Instructions:

    2. Ensure that the threads and shoulder of both the barrel and Pro Muzzle Brake are clean and free from any dust, debris, dried locking compound or rust.
    3. Using included shim kit, install the thickest spacer first followed by the thinner spacers as required to achieve proper timing or orientation. The brake ports should be aligned in the horizontal to the plane of the weapon so that the excess gasses are vented to the sides.
    4. When torqueing the brake onto the barrel, the wrench should be placed on the rearmost flat of the brake closest to the threaded end behind the first array of ports.
