Lightweight clamp on muzzle brake for the Mosin Nagant rifle has been precision CNC machined from 7075-T651 Aluminum and then Type III Hardcoat Anodized in a matte black color.

These brakes offer a substantial reduction in felt recoil and muzzle rise of approximately 60-70% while significantly improving comfort during firing.This design incorporates a twist lock design that will fit around the standard front sight.

7075-T651 Aluminum has a tensile strength of 83,000psi, yield strength of 73,000 psi, and a shear strength of 48,000 psi. These values are before the hardcoat anodizing which creates an outer layer on the aluminum that specs out at 60 Rockwell.

There are 20 .078" holes drilled into the top of the brake that vent gas in order to stop muzzle rise. The bottom of the brakes have no holes or ports to kick up dirt all over the shooter. Having the bottom of the brake angled outward also helps to reduce muzzle rise.

As part of our manufacturing process after the muzzle brakes are machined they are finished with a large vibratory tumbler using Ceramic media in order to provide a smooth matte finish prior to Anodizing.
