Firearms recoil reducer

Abstract

The present invention relates to firearms recoil reducer. Current reducers are some type of shock absorbers with limited efficiency, of about 15%. The lift and the back kick of the firearm remain causing pain to the shoulder and instability in targeting especially with repeating firearms. In my invention the combined recoil of primary recoil associated with bullet speed and about four folds more powerful secondary recoil associated with exploding gas burst leaving the front of the barrel are countered by the backwards puff of the burst by the recoil reducer. The secondary recoil resulting from exploding gas burst leaving the barrel is utilized to nullify the primary and part of the secondary recoil. My recoil reducer is a wide cap absorbing the explosion and pulling forward the muzzle to counter the native recoil. The recoil reduction is further maximized or reinforced by a duckbill valve, by wide flat cap, by flat cap with side walls or rims, and by a cup shaped reducer with a hole in its bottom part. The force of recoil is adjustable by the space between muzzle and reducer. The recoil reducer can be multiple backward slanted holes or grooves with a collar around the muzzle to guide the explosion gas burst backwards to counter the original combined recoil.

1 . A recoil reducer comprising a cap attached to the muzzle by a connector, said connector is fastened to the muzzle on one side and to the reducer on the other, said connection to the muzzle is at a point behind the gun targeting front sight, said connection is fastened and tightened by adjustment screw, said reducer cap is preferably of strong metal sheet that reflects the burst of exploded gas in front of the barrel, said cap has a center hole slightly wider in size than that of the barrel to allow the bullet or projectile to continue in its trajectory to wards target, said cap is fastened to the connector, said cap can be a plain sheet of metal with center hole, a plain sheet with side walls or rims, a cap in the shape of a cup with a center hole in the bottom of the cup base, said cap or cup has its opening pointing slanted upwards to control uplift, said cap can also have a duck bill valve to maximize the bouncing back gas burst pressure that in turn cause the reducer cap to pull the muzzle forwards to counter the primary recoil and the original kickback. The magnitude of recoil reduction is adjustable by the distance of the cap from the front part of the muzzle, by the area, volume, and configuration of the cap, by the duckbill valve, by the height of side walls or rims, by the number and size of the backward slanted groove in the muzzle wall, and by the size, depth, and orientation of the cap around the outside wall of the muzzle over the slanted holes or over the backward slanted grooves in the muzzle wall.  
   
   
       2 . As in  claim 1  where the reducer cap has a duckbill valve that closes after the projectile go through for maximizing the frontward pulling of the muzzle by the reducer cap. through connector  
   
   
       3 . As in  claim 1  with reducer cap being flat metal with center hole  
   
   
       4 . As in  claim 1  with cap being flat metal with center hole and with side walls.  
   
   
       5 . As in  claim 1  with cap reducer being slanted backwards multiple holes or deep grooves reaching the barrel in the front portion of the muzzle wall.  
   
   
       6 . As in  claim 1  with cap reducer being multiple perpendicular holes at the front part of the muzzle with external surrounding cap to guide the expanding gas burst to jet backwards.  
   
   
       7 . As in  claim 1  with cap opening slanted upwards to reduce uplift
