Muzzle Break

Abstract

A muzzle break which directs propelling gases rearward and upward to reduce both recoil and muzzle jump. The gases are redirected by curved vanes which extend from a tapered central bore whose diameter decreases in the shooting direction.

1 . A muzzle break comprising a body having a central bore lying on an axis defining a shooting direction and a plurality of passages leading away from the bore on opposite sides of the central bore to ports at the surface of the body, the passages being defined by a plurality of curved vanes so that at least some of the passages are shaped to direct propelling gas in a direction having a rearward component, with respect to the shooting direction, and means for connecting the muzzle break to a barrel of a gun. 
     
     
         2 . The invention of  claim 1 , wherein at least some of the passages are inclined upward with respect to a horizontal plane containing the shooting direction, so that there is a net downward force on the barrel of the gun when it is discharged to counter barrel jump. 
     
     
         3 . The invention of  claim 1 , wherein the central bore is tapered, having a diameter which decreases in the shooting direction.
