Weapon system modification directed to short stroke piston assembly

Abstract

An improved weapon system modification directed to short stroke piston assemblies comprising: a housing having an inlet port for receiving gas from a barrel, a piston chamber and a piston contained within the chamber that, when actuated by gas, moves rearward toward a chamber contacting a bolt carrier and cycling the action; a front seating ring for receiving a front sleeve; a rear seating ring for receiving a rear sleeve; a barrel extending through the front sleeve, housing and rear sleeve defining one or more voids between the front sleeve, housing and rear sleeve and the barrel; filler material deposited and/or disposed in the void(s) that when cured or hardened, results in a barrel assembly dissipating heat and improving accuracy; a receiver plate included in the housing for attaching the housing to a receiver; a receiver block included in the housing for attaching the housing to the receiver; and, a lower track that can be attached to the housing and a barrel locking collar.

What is claimed is: 
     
         1 . A weapon system comprising:
 a housing having a housing bore configured to receive a barrel and having a piston chamber configured to receive a gas piston;   a receiver plate attached to the housing;   a receiver block attached to the housing;   a forward seating ring attached to the housing;   a forward sleeve attached to the forward seating ring;   a forward void defined between the barrel and the forward sleeve;   a rear seating ring attached to the housing;   a rear sleeve attached to the rear seating ring and disposed between the housing and a barrel locking collar;   a rear void defined by the barrel and the rear sleeve; and,   a filler material disposed in the forward void and the rear void.   
     
     
         2 . The weapon system of  claim 1  including a housing void defined between the forward seating ring, the rear seating ring and the barrel wherein the filler material is disposed in the housing void. 
     
     
         3 . The weapon system of  claim 1  wherein the receiver plate and the receiver block are removable attached to a receiver. 
     
     
         4 . The weapon system of  claim 3  including a gas port defined in the housing to transfer gas from an interior of the barrel to the piston chamber. 
     
     
         5 . The weapon system of  claim 4  including a fastening means extending through the receiver and into the receiving block to secure the housing to the receiver. 
     
     
         6 . The weapon system of  claim 1  including a sling attachment point defined in the receiver plate. 
     
     
         7 . The weapon system of  claim 1  including an end cap attached to the forward sleeve at a distal end. 
     
     
         8 . A weapon system comprising:
 a housing having a housing bore configured to receive a barrel and configured to be attached to a receiver;   a receiver plate attached to the housing;   a forward sleeve attached to the housing and configured to receive the barrel;   a forward void defined between the barrel and the forward sleeve;   a rear sleeve attached to the housing and configured to receive the barrel;   a rear void defined by the barrel and the rear sleeve; and,   a filler material disposed in the forward void and the rear void.   
     
     
         9 . The weapon system of  claim 8  including a piston chamber included in the housing and configured to receive a gas piston. 
     
     
         10 . The weapon system of  claim 8  including a receiver block attached to the housing and configured to attach to the receiver. 
     
     
         11 . The weapons system of  claim 8  including a sling attachment point attached to the housing. 
     
     
         12 . The weapon system of  claim 8  including a forward seating ring attached to the housing configured to receive the forward sleeve. 
     
     
         13 . The weapon system of  claim 8  including a rear seating sleeve attached to the housing and configured to receiving the rear sleeve. 
     
     
         14 . A weapon system comprising:
 a housing having a housing bore configured to receive a barrel;   a piston chamber attached to the housing and configured to receive a gas piston and gas from an interior of the barrel;   a receiver plate attached to the housing;   a sleeve attached to the housing and configured to receive the barrel;   a void defined between the barrel and the sleeve; and,   a filler material disposed in the void.   
     
     
         15 . The weapon system of  claim 14  including a receiver block attached to the housing configured to be removably attached to a receiver. 
     
     
         16 . The weapon system of  claim 14  wherein the sleeve is disposed between the housing and a barrel locking collar attached to the barrel. 
     
     
         17 . The weapon system of  claim 14  including wherein the sleeve is disposed between the housing and a muzzle end of the barrel. 
     
     
         18 . The weapon system of  claim 17  including an end cap affixed to a distal end of the sleeve. 
     
     
         19 . The weapon system of  claim 14  including a seating ring configured to receive the sleeve. 
     
     
         20 . The weapon system of  claim 14  including an outer edge of the receiver plate that extends into a receiver when the receiver plate is received into the receiver.
