Interchangeable Chamber and Barrel System

Abstract

An interchangeable chamber and barrel system for allowing an end user to easily change a chamber body and/or a barrel for a firearm without the assistance of a gunsmith. The interchangeable chamber and barrel system generally includes an interchangeable chamber body having a chamber that is removably connectable to a receiver of a firearm and an interchangeable barrel that is removably connected to the chamber body opposite of the receiver. The chamber body and/or the barrel may be changed on the firearm at any time based on the preference of the end user.

         9 . The interchangeable chamber of  claim 1 , wherein the second opening extends inwardly to a distal end of the neck of the chamber. 
     
     
         10 . The interchangeable chamber of  claim 9 , wherein a diameter of the second opening is larger than a diameter of the neck of the chamber. 
     
     
         11 . An interchangeable chamber body and barrel for a firearm, comprising:
 a barrel having an inner end, a muzzle end and a bore extending between the inner end and the muzzle end, wherein the inner end includes an inner connector;   a chamber body having a first end and a second end, wherein the first end of the chamber body includes a first connector adapted to be connected to a receiver of a firearm and wherein the second end includes a second connector that is connected to the inner connector of the barrel;   a first opening extending into the first end of the chamber body;   a second opening extending into the second end of the chamber body; and   a chamber within the chamber body, wherein the chamber includes a body portion extending forward from a first end of the chamber, a tapering shoulder extending forwardly from the body portion, and a neck extending forwardly from the tapering shoulder to a second end of the chamber, wherein the body portion of the chamber is adapted to receive a case body of an ammunition cartridge, wherein the tapering shoulder of the chamber is adapted to receive a case neck of the ammunition cartridge, wherein the neck of the chamber is adapted to completely receive a case neck of the ammunition cartridge, wherein the chamber is connected to the first opening at the first end of the chamber and the second opening at the second end of the chamber, wherein the chamber is completely within the chamber body, and wherein the chamber is adapted to receive at least a portion of the ammunition cartridge such that the second end of the chamber is forward of a distal end of the case neck of the ammunition cartridge.   
     
     
         12 . The interchangeable chamber and barrel of  claim 11 , wherein the first opening is part of the chamber. 
     
     
         13 . The interchangeable chamber and barrel of  claim 11 , wherein the chamber body is constructed of a first unitary piece of metal and wherein the barrel is constructed of a second unitary piece of metal separate of the first unitary piece of metal. 
     
     
         14 . The interchangeable chamber and barrel of  claim 11 , wherein the chamber body includes a plurality of gripping members for selective engagement by a tool. 
     
     
         15 . The interchangeable chamber and barrel of  claim 11 , wherein the first connector is comprised of outer threading surrounding a portion of the first end of the chamber body that is adapted to threadably connect to an interiorly threaded receiver opening in the receiver.
