Our brakes incorporate a chamber section to increase gas flow and thus reduce recoil. Estimated reduction in felt recoil is approximately 50%. Unlike some commercially available brakes that are simply a hole for your bullet to pass through and a series of holes drilled into the sides of the brake, we have removed all material except the outer wall of the brake. This creates a larger chamber section for gas flow. The holes are cut at varying angles to vent gas which in turn reduces recoil by basically pulling the rifle away from you.  While we have found other muzzle brakes to reduce recoil, the design of the McGowen Turbo Brake creates a chamber that accentuates the performance of the muzzle brake by creating a chamber withing the brake that redirects the gases to actually pull the firearm away from the shooter.  Thus, creating a more effective recoil reduction.
