Reverse thrust system with integral conduits and nozzles for the reduction of muzzle jump and/or recoil in firearms and weapons

Abstract

A projectile firing gun or weapon barrel is adapted with a gas porting system having conduits and outlets specifically configured and positioned for maximizing reductions in muzzle jump and recoil. Principles of reverse thrust are maximized to reduce muzzle jump by incorporating porting holes located toward the butt end of the barrel, which porting holes are in fluid communication with gas conduits terminating in upwardly directed openings for maximizing the generation of downward thrust forces. Venting explosion gases in a substantially upward direction maximizes downward vector thrust force to counteract muzzle jump. Venting the explosion gases at the butt end of the barrel maximizes the duration of thrust forces as gases are vented well prior to the projectile exiting the barrel. The conduits may be configured with nozzle outlets so as to redirect and concentrate the escaping gases thereby maximizing the forces to counter muzzle jump and recoil.

What I claim is:  
     
         1 . An apparatus for reducing muzzle jump of a firearm or weapon having a barrel section defining a substantially uniform diameter axial bore through which a projectile travels under the influence of expanding gases generated by explosive material, said apparatus comprising: 
 a barrel defined by a generally cylindrical barrel wall surrounding an axis, said barrel wall defining at least a pair of through bores extending therethrough on opposing lower left and right sides of said barrel for redirecting a portion of the gases produced by the explosive material upon firing of the firearm;    a rigid body attached to an outer portion of said barrel wall, said body having a U-shaped portion for receiving a portion of the barrel therein in mating engagement therewith, said body defining left and right conduits having inlets in corresponding communication with said left and right through bores, each of said conduits having an outlet configured for discharging gases on opposing left and right sides of said barrel in a vertically upward and generally perpendicular direction relative to said barrel axis.    
     
     
         2 . An apparatus for reducing muzzle jump of a firearm or weapon according to  claim 1 , wherein said each of said conduit outlets are defined by diverging conduit walls.  
     
     
         3 . An apparatus for reducing muzzle jump of a firearm or weapon according to  claim 1 , wherein said each of said conduit outlets are defined by converging conduit walls.  
     
     
         4 . An apparatus for reducing muzzle jump of a firearm or weapon according to  claim 1 , wherein said body further defines a second set of left and right conduits in communication with at least one through bore, said second set of left and right conduits each configured to vent gas in a rearward direction for reducing recoil.  
     
     
         5 . An apparatus for reducing muzzle jump of a firearm or weapon according to  claim 1 , further including means for diverting high pressure gas from said barrel to a gas cylinder of said firearm or weapon to actuate gas operated action.  
     
     
         6 . An apparatus for reducing muzzle jump of a firearm or weapon having a barrel section defining a substantially uniform diameter axial bore through which a projectile travels under the influence of expanding gases generated by explosive material, said apparatus comprising: 
 a barrel defined by a generally cylindrical barrel wall formed about an axis, said barrel wall defining at least one through bore extending therethrough for redirecting a portion of the gases produced by the explosive material upon firing of the firearm;    a rigid body attached to an outer portion of said barrel wall, said body having a U-shaped portion for receiving a portion of the barrel therein in mating engagement therewith, said body defining left and right conduits, each of said conduits having an inlet in communication with said at least one through bore, each of said conduits having an outlet configured for discharging gases on opposing left and right sides of said barrel in a vertically upward and generally perpendicular direction relative to said barrel axis.    
     
     
         7 . An apparatus for reducing muzzle jump of a firearm or weapon according to  claim 6 , wherein said each of said conduit outlets are defined by diverging conduit walls.  
     
     
         8 . An apparatus for reducing muzzle jump of a firearm or weapon according to  claim 6 , wherein said each of said conduit outlets are defined by converging conduit walls.
