Abstract

A monolithic barrel for a weapon has an integral suppressor. The barrel and integral suppressor can be machined from a single piece of material, which can eliminate the need to attach separate components to the barrel. The monolithic barrel has a barrel bore for firing a projectile that produces discharge gas. To suppress the discharge, the barrel defines one or more baffles separating expansion chambers toward a distal end of the barrel. The barrel further defines one or more channels along the length of the barrel that provide extend flow paths for the discharge gas from the barrel's bore. Greater reductions in sound can be achieved relative to the overall barrel length due to the integral suppressor.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A barrel for a weapon having a receiver and firing a projectile that produces discharge gas, the barrel comprising:
 a barrel body having an exterior and defining a bore therethrough from a proximal end to a distal end, the proximal end connecting to the receiver,   the barrel body defining one or more channels, the one or more channels being enclosed by the exterior and being integrated along a first length of the barrel body,   the bore defining one or more ports communicating the bore with the one or more channels,   the one or more ports communicating the discharge gas between the bore and the one or more channels.   
     
     
         2 . The barrel of  claim 1 , wherein the exterior of the barrel body comprises a tubular disposed external to the barrel body and enclosing the one or more channels. 
     
     
         3 . The barrel of  claim 2 , wherein at least one end of the tubular affixes to the barrel body. 
     
     
         4 . The barrel of  claim 2 , wherein the tubular seals at least partially to the barrel body. 
     
     
         5 . The barrel of  claim 1 , wherein the barrel body further defines one or more baffles being integrated along a second length of the barrel body and defining one or more chambers internally communicating with a portion of the bore. 
     
     
         6 . The barrel of  claim 5 , wherein the exterior of the barrel body comprises a tubular disposed external to the barrel body and enclosing the one or more chambers. 
     
     
         7 . The barrel of  claim 1 , wherein the proximal end of the barrel body comprises a breech adapted to connect to the receiver. 
     
     
         8 . The barrel of  claim 7 , wherein the breech defines a chamber communicating with a throat of the bore in the barrel body. 
     
     
         9 . The barrel of  claim 1 , wherein the bore defines rifling from toward the proximal end up to at least the one or more cross ports. 
     
     
         10 . The barrel of  claim 1 , wherein the barrel body defines a gas port therein communicating at an inlet with a portion of the bore and communicating at an outlet with a portion of the receiver. 
     
     
         11 . The barrel of  claim 1 , wherein the barrel body defines a gas port therein communicating at an inlet with a portion of the barrel bore and communicating at an outlet with an external line disposed along the barrel body to the receiver. 
     
     
         12 . The barrel of  claim 1 , wherein the barrel body is composed of first and second materials, the second material formed as an insert disposed in the first material, the insert having at least a portion of the bore. 
     
     
         13 . The barrel of  claim 1 , wherein the barrel body is composed of a monolithic piece of material defining at least the bore, the one or more cross ports, and the one or more channels integrally therein. 
     
     
         14 . The barrel of  claim 1 , wherein the barrel body is composed of a monolithic piece of first material having a tubular piece of second material as the exterior disposed thereabout, the monolithic piece defining at least the bore, the one or more cross ports, and the one or more channels integrally therein, the tubular enclosing the one or more channels. 
     
     
         15 . A weapon for firing a projectile that produces discharge gas, the weapon comprising:
 a receiver; and   a barrel body having an exterior and defining a bore therethrough from a proximal end to a distal end, the proximal end connecting to the receiver,   the barrel body defining one or more channels, the one or more channels being enclosed by the exterior and being integrated along a first length of the barrel body,   the bore defining one or more ports communicating the bore with the one or more channels,   the one or more ports communicating the discharge gas between the bore and the one or more channels.   
     
     
         16 . The weapon of  claim 15 , wherein the receiver comprises a receiver of a rifle. 
     
     
         17 . A method of manufacturing a barrel for a weapon used for firing a projectile that produces discharge gas, the method comprising:
 integrating one or more channels along a first length of a barrel body;   communicating the one or more integrated channels with a bore of the barrel body; and   enclosing the one or more integrated channels internally in communication with the bore.   
     
     
         18 . The method of  claim 17 , wherein integrating the one or more channels along the first length of the barrel body comprises machining one or more flutes as the one or more channels along the first length of the barrel body in an external surface thereof. 
     
     
         19 . The method of  claim 18 , wherein communicating the one or more integrated channels with the bore of the barrel body comprises defining one or more ports in the barrel body communicating the one or more flutes with the bore. 
     
     
         20 . The method of  claim 18 , wherein enclosing the one or more integrated channels internally in communication with the bore comprises disposing a tubular at least partially about the external surface of the barrel body. 
     
     
         21 . The method of  claim 17 , further comprising integrating one or more chambers separated by baffles in a second length of the barrel body and in communication with the bore. 
     
     
         22 . The method of  claim 21 , further comprising enclosing the one or more integrated chambers internally in communication with the bore. 
     
     
         23 . The method of  claim 22 , wherein enclosing the one or more integrated chambers internally in communication with the bore comprises disposing a tubular at least partially about the external surface of the barrel body. 
     
     
         24 . The method of  claim 17 , comprising initially taking a monolithic piece of first material for the barrel body having the bore, wherein integrating the one or more channels and communicating the one or more integrated channels with the bore are performed in the monolithic piece. 
     
     
         25 . The method of  claim 24 , wherein enclosing the one or more integrated channels internally in communication with the bore comprises disposing a tubular piece of second material outside at least a portion of the monolithic piece of the first material. 
     
     
         26 . The method of  claim 17 , comprising initially taking a tubular piece of first material for the barrel body having the bore and disposing the tubular piece in a surrounding piece of second material for the barrel body.
