If you own a Mosin Nagant, which I’m sure many of you do, then you probably know that sore feeling the day after shooting it. The folks over at Witt Machine have come up with something to help take away some of the sting from shooting 7.62x54r. They have some pretty interesting looking muzzle brakes for the 91/30 and M44/M44 Type 53 Mosin Nagants. They’re CNC machined from 7075-T651 Aluminum and hardcoat anodized. According to Witt Machine they reduce 60 to 70% of the Mosin’s recoil and muzzle rise. Their muzzle brakes simply twist on around the front sight and are held in place with screws. The M44/M44 Type 53 muzzle brake retails for $89 and the 91/30 muzzle brake retails for $85. Check it out in action below.
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.
During testing we found that the 5 port design makes the most efficient use of the available gasses exiting the barrel to substantially reduce recoil. 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. The brakes can be used as is, or painted/coated with any of the gun coatings commercially available. We also offer Cerakote coating on all of our brakes.
