Composite bolt carrier and side charge gas reservoir apparatus for a weapon simulator

Abstract

A composite bolt carrier for a firearm simulator actuator which provides pneumatic recoil for a firearm simulator employing a metal receiver. The composite bolt carrier includes a first segment constructed of a material which is softer than the metal receiver and a second segment constructed of a material of greater mass than the material of the first segment. A simulated recoil assembly for a semi-automatic rifle having a receiver with an ejection port including an actuator adapted to reciprocate within the receiver upon metered delivery of compressed gas; and a compressed gas reservoir in fluid communication with the actuator through the ejector port.

         3 . A composite bolt carrier having a shape for a rifle simulator actuator which provides pneumatic recoil and the firearm employs a receiver, the composite bolt carrier comprising:
 a polymer segment;   a second segment heavier than said polymer segment adapted to add mass to the composite bolt carrier;   wherein said polymer segment comprises the majority of the shape of the composite bolt carrier.   
     
     
         4 . The composite bolt carrier of  claim 3  wherein said polymer segment and said second segment are joined together. 
     
     
         5 . A simulated recoil assembly for a semi-automatic rifle having a receiver with an ejection port, comprising:
 an actuator adapted to reciprocate within the receiver upon metered delivery of compressed gas;   a compressed gas reservoir in fluid communication with said actuator through the ejection port.   
     
     
         6 . The simulated recoil assembly of  claim 5  wherein said actuator comprises:
 a bolt carrier including a piston slot; 
 a piston adapted to be received within said piston slot such that said bolt carrier is adapted to reciprocate with respect to a stationary piston. 
 
     
     
         7 . The simulated recoil assembly of  claim 6  further including a passage bolt extending through the ejection port connecting said compressed gas reservoir with said actuator. 
     
     
         8 . The simulated recoil assembly of  claim 7  comprising:
 said passage bolt includes a T-slot; 
 said piston including a base and a stem; 
 said base including a notch for mating with said T-slot. 
 
     
     
         9 . The simulated recoil assembly of  claim 7  wherein said passage bolt includes a T-slot for mating with said actuator. 
     
     
         10 . The simulated recoil assembly of  claim 5  wherein said actuator reciprocates within the receiver and including a magazine to count reciprocations of said actuator. 
     
     
         11 . The simulated recoil assembly of  claim 10  including a bolt catch for catching said bolt carrier following a predetermined number of reciprocations. 
     
     
         12 . The simulated recoil assembly of  claim 6  including a laser pointer activated upon reciprocation of said bolt carrier. 
     
     
         13 . The simulated recoil assembly of  claim 12  including a laser activation switch which senses reciprocations of said actuator. 
     
     
         14 . The simulated recoil assembly of  claim 6  wherein the semi-automatic rifle includes a hammer and said bolt carrier includes a hammer cavity for receiving said hammer. 
     
     
         15 . The simulated recoil assembly of  claim 14  wherein said bolt carrier includes a hammer impact stop positioned at an angle less than vertical. 
     
     
         16 . The simulated recoil assembly of  claim 6  wherein said bolt carrier has a shape and comprises:
 a polymer segment; 
 a second segment heavier than said polymer segment adapted to add mass to the composite bolt carrier; 
 wherein said polymer segment comprises the majority of the shape of the composite bolt carrier. 
 
     
     
         17 . The simulated recoil assembly of  claim 5  wherein said gas pressure vessel is refillable.
