Piercision Rifles Muscle Brake
This is the new Self Timing 3 port brake. The first port is a 90-degree port which acts as a shield to keep the blast from the other two ports from coming back at the shooter or shooters next to them. It does a very good job of reducing recoil and muzzle jump. Available in 6.5 and 308
Both 6.5 and 308 are 5/8x24 threads.
