Muzzle brake and method

Abstract

A muzzle gas reduction device has upper and lower elongated, curved sections that define a barrel shape that is open to the sides. The upper section has a narrower width than the lower section. A plurality of cone-shaped, open, combs are interposed between the upper and lower elongated sections, along a length thereof. The device is coupled to the end of a barrel of a firearm, preferably a PAN disrupter. The configuration of the cones and the differing widths of the upper and lower sections cause muzzle gasses to be re-directed rearward and upward, reducing recoil.

1 . A muzzle gas reduction device comprising, in combination:
 an upper, elongated, curved section having a first width;   a lower, elongated, curved section having a second width greater than that of the first width;   wherein the upper and lower, elongated, curved sections define a barrel open to sides thereof;   a plurality of cone-shaped combs interposed at intervals along the barrel defined by the upper and lower, elongated, curved sections;   wherein each of the cone-shaped combs has an opening therethrough sufficient to permit passage of a projectile; and   a coupling device adapted to couple the barrel of the muzzle gas reduction device to a barrel of a firearm.   
   
   
       2 . The muzzle gas reduction device of  claim 1 , wherein there are at least three cone-shaped combs. 
   
   
       3 . The muzzle gas reduction device of  claim 1 , wherein there are at least four cone-shaped combs. 
   
   
       4 . The muzzle gas reduction device of  claim 1 , wherein there are at least five cone-shaped combs. 
   
   
       5 . The muzzle gas reduction device of  claim 1  wherein the coupling device comprises an elongated section having a diameter less than that of the barrel defined by the upper and lower, elongated, curved sections and a clamping device adapted to clamp the elongated section of the muzzle gas reduction device to the barrel of the firearm. 
   
   
       6 . The muzzle gas reduction device of  claim 1  further comprising a percussion actuated non-electric disrupter and wherein the muzzle gas reduction device is coupled to the percussion actuated non-electric disrupter. 
   
   
       7 . The muzzle gas reduction device of  claim 1  wherein the combs are evenly-spaced, one from the other. 
   
   
       8 . A muzzle gas reduction device comprising, in combination:
 an upper, elongated, curved section having a first width;   a lower, elongated, curved section having a second width greater than that of the first width;   wherein the upper and lower, elongated, curved sections define a barrel open to sides thereof;   at least three cone-shaped combs interposed at intervals along the barrel defined by the upper and lower, elongated, curved sections;   wherein each of the cone-shaped combs has an opening therethrough sufficient to permit passage of a projectile; and   a coupling device adapted to couple the barrel of the muzzle gas reduction device to a barrel of a firearm;   wherein the firearm is a percussion actuated non-electric disrupter.   
   
   
       9 . The muzzle gas reduction device of  claim 8  wherein the coupling device comprises an elongated section having a diameter less than that of the barrel defined by the upper and lower, elongated, curved sections and a clamping device adapted to clamp the elongated section of the muzzle gas reduction device to the barrel of the firearm. 
   
   
       10 . The muzzle gas reduction device of  claim 8  wherein the combs are evenly-spaced, one from the other. 
   
   
       11 . A method for reducing muzzle gas and recoil comprising, in combination:
 providing a muzzle gas reduction device in accordance with  claim 1 ;   coupling the muzzle gas reduction device to a barrel of a firearm; and   discharging the firearm.   
   
   
       12 . The method of  claim 11  wherein the firearm is a percussion actuated non-electric disrupter.
