Dummy assault rifle

Abstract

Converting a functioning assault rifle to an inoperative dummy gun suitable for collectors by replacing the receiver with a receiver filled with a solid material. The filled spaces of the receiver prevent the cooperative operation with the other components of the gun. The dummy receiver is externally indistinguishable from the functioning receiver. Thus, a model rifle is converted for collectors so as to be unrecognizable from the functioning gun. To accommodate the filled spaces in the receiver, the lower part of the cooperating bolt carrier is milled off. The dummy receiver may include an affixed rear sight base.

1 . A dummy receiver for disabling an operative gun while maintaining its external appearance, the gun including a functioning receiver, a cartridge magazine, a trigger mechanism with a firing pin, and a barrel, the dummy receiver comprising: 
 an elongated receiver, sized and shaped to correspond to the functioning receiver and cooperating with the functioning magazine and trigger mechanism;    said elongated receiver including solid material filling the space where the cartridge would be received from the magazine in an operative receiver;    whereby, said dummy receiver, by replacing the functioning receiver, prevents the operation of the gun.    
   
   
       2 . A dummy receiver according to  claim 1 , further comprising: 
 a filled space of solid material in a place where a bolt carrier would normally be located.    
   
   
       3 . A dummy receiver according to  claim 2 , further comprising; 
 a filled space of solid material in the area of the trigger mechanism.    
   
   
       4 . A dummy receiver according to  claim 1 , in combination with a bolt carrier, the bolt carrier including a bolt and locking piece, and wherein a lower part of the bolt carrier is at least partially received within the receiver; 
 wherein the receiver is filled with solid material in the space of the lower part of the bolt carrier;    and said lower part of the bolt carrier is at least partially removed to accommodate the solid material in the said space of the lower part of the bolt carrier.    
   
   
       5 . A dummy receiver in combination with a bolt carrier according to  claim 4 , wherein the lower part of the bolt carrier includes only a partial opening for the firing pin.  
   
   
       6 . A dummy receiver in combination with a bolt carrier according to  claim 5 , wherein the firing pin opening is semi-cylindrical in cross section.  
   
   
       7 . A dummy receiver according to  claim 1 , wherein said solid filling material is softer than the material of the barrel.  
   
   
       8 . A dummy receiver according to  claim 7 , wherein said solid filling material is aluminum.  
   
   
       9 . A dummy receiver according to  claim 7 , wherein said solid filling material is plastic.  
   
   
       10 . A dummy receiver according to  claim 1 , further comprising a rear sight base fixed to said dummy receiver.  
   
   
       11 . A dummy receiver according to  claim 1 , further comprising a rear sight base; 
 and wherein said rear sight base is affixed to the barrel of the gun.    
   
   
       12 . A dummy receiver according to  claim 1 , wherein the gun is an Sa vz.58 assault rifle.  
   
   
       13 . A method of converting a gun into a dummy weapon, the gun including a functioning receiver, a cartridge magazine, a trigger mechanism with a firing pin, and a barrel, the method comprising: 
 providing a dummy receiver in the shape of the functioning receiver: 
 filling particular areas of an internal space of the dummy receiver with solid material;  
 removing the functioning receiver; and  
 replacing the functioning receiver with said dummy receiver;  
   whereby functioning parts of the gun cannot be received in the dummy receiver and the gun is disabled while maintaining its original external appearance.    
   
   
       14 . A method of converting a gun according to  claim 13 , wherein the gun further includes a functioning bolt carrier, the bolt carrier including a bolt and locking piece, and wherein a lower part of the bolt carrier is at least partially received within the receiver; the method further comprising: 
 milling off said lower part of the bolt carrier.    
   
   
       15 . A method of converting a gun according to  claim 14 , wherein the lower part of said functioning bolt carrier includes an opening for the firing pin of the trigger mechanism, the method further comprising: 
 removing the lower portion of said opening up to the middle of the functioning firing pin opening by a milling-off process.    
   
   
       16 . A method of converting a gun according to  claim 13 , further comprising: 
 providing a dummy receiver including an attached rear sight base.    
   
   
       17 . A method of converting a gun according to  claim 13 , wherein said functioning gun includes a rear sight base attached to the receiver, and wherein the method further comprises: 
 affixing said rear sight base to said barrel; and    cutting said rear sight base from its attachment to the functioning receiver.    
   
   
       18 . A method of converting a gun according to  claim 13 , wherein the functioning gun is an Sa vz.58 model assault rifle.
