Firearm receivers with hollow body profiles and methods of producing the same

Abstract

In one example, a weapon component is disclosed. The component includes a receiver and a hollow body profile. The hollow body profile is formed as an injection molded portion wherein the hollow body profile is integral with and reinforces the receiver. Further, the hollow body profile forms one edge of a cartridge case ejector window.

1 . A weapon component comprising: 
 a receiver; and    a hollow body profile formed as an injection molded portion wherein the hollow body profile is integral with and reinforces the receiver and wherein the hollow body profile forms one edge of a cartridge case ejector window.    
     
     
         2 . A component as defined in  claim 1 , wherein: 
 the weapon further includes a scope axis;    the receiver further includes a shaft region; and    the hollow body profile includes a first section that runs in the shaft region in the direction of the scope axis.    
     
     
         3 . A component as defined in  claim 1 , wherein the shaft region includes a scope side end and the hollow body profile further includes a second section that is constructed essentially vertically to the scope axis at the scope side end.  
     
     
         4 . A component as defined in  claim 1 , further comprising a bush, wherein the bush is embedded in the receiver, couples a scope and includes a face that points toward the shaft region of the receiver.  
     
     
         5 . A component as defined in  claim 4 , wherein the bush is made of one of a metal or a carbon-fiber impregnated plastic material.  
     
     
         6 . A component as defined in  claim 4 , wherein the bush holds a braking system of the scope or a breech mechanism in addition to or instead of the scope.  
     
     
         7 . A component as defined in  claim 6 , wherein the scope is in one of stationary or flexible arrangement in the bush in the direction of the axis.  
     
     
         8 . A component as defined in  claim 4 , further comprising a recess that exposes a portion of an outer surface of the bush.  
     
     
         9 . A component as defined in  claim 4 , wherein the bush further includes holes for anchoring in the receiver.  
     
     
         10 . A component as defined in  claim 1 , wherein the hollow body profile includes at least one of closing magnets or hinged elements of a cover flap of the cartridge case ejector window.  
     
     
         11 . A component as defined in  claim 1 , wherein the first section is arranged largely in the interior of the receiver.  
     
     
         12 . A component as defined in  claim 11 , wherein the hollow body profile has outer surfaces in the interior of the receiver that guide a breech element.  
     
     
         13 . A component as defined in  claim 12 , wherein the breech element is a breechblock carrier.  
     
     
         14 . A method of forming a weapons component, the method comprising: 
 molding a receiver;    forming a profile integrally with the receiver, wherein at least a portion of the profile is formed to be an edge of a cartridge ejection window; and    injecting the profile with a first material to form a hollow space in the profile.    
     
     
         15 . A method of forming a weapons component as defined in  claim 14 , wherein the first material is a gas.  
     
     
         16 . A method of forming a weapons component as defined in  claim 14 , further comprising filling the hollow space with a second material.  
     
     
         17 . A method of forming a weapons component as defined in  claim 16 , wherein the second material is at least one of elastomer, artificial resin, or foam.  
     
     
         18 . A method of forming a weapons component as defined in  claim 14 , wherein the first material is injected via a needle.  
     
     
         19 . A method of forming a weapons component as defined in  claim 14 , wherein the component is a plastic material.  
     
     
         20 . A method of forming a weapons component as defined in  claim 19 , wherein the plastic is polyamide.  
     
     
         21 . An automatic or semi-automatic firearm for use with large-caliber ammunition, the firearm comprising: 
 a receiver; and    a hollow body profile integrally formed with the receiver wherein the hollow body profile forms one edge of a cartridge case ejector window.
