Abstract
Assemblies such as firearms having a barrel including a throat insert are disclosed. In some embodiments, an assembly includes a barrel, a throat region having a throat insert disposed therein, and a bore extending away from the throat region to a muzzle end of the barrel. During firing, a bullet from an ammunition cartridge disposed within the chamber passes through an insert passage and the bore, and exits from the bore through a discharge opening. The throat insert is formed of a material (e.g. brass, titanium, etc.) that is at least one of harder or more durable than the material of the barrel. Because the throat insert is proximate the chamber, the throat insert bears the extreme environment (e.g. heating, pressure, etc.) during firing of the ammunition cartridge.
Claims20
An assembly, comprising:
- a barrel having a throat end positionable proximate to a chamber, a throat region disposed within the throat end of the barrel, and a bore extending away from the throat region to a muzzle end of the barrel spaced apart from the throat end, the bore being configured to allow a bullet from an ammunition cartridge disposed within the chamber to pass through the bore and to exit through a discharge opening proximate the muzzle end;
- and
- a throat insert disposed within the throat region of the barrel, the throat insert including an insert passage substantially aligned with the bore, the insert passage being configured to allow the bullet from the ammunition cartridge to pass through the insert passage and into the bore, the throat insert being formed of a different material than the barrel.
A firearm assembly, comprising:
- a chamber configured to securely position an ammunition cartridge, the chamber having an exit opening configured to allow a bullet from the ammunition cartridge disposed within the chamber to pass through the exit opening;
- a barrel having a throat end proximate to the chamber, a throat region disposed within the throat end, and a bore extending away from the throat region to a muzzle end of the barrel spaced apart from the throat end, the bore being configured to allow the bullet from the ammunition cartridge disposed within the chamber to pass through the bore and to exit through a discharge opening proximate the muzzle end;
- and
- a throat insert disposed within the throat region of the barrel, the throat insert including an insert passage substantially aligned with the exit opening of the chamber and substantially aligned with the bore, the insert passage being configured to allow the bullet from the ammunition cartridge to pass through the insert passage and into the bore, the throat insert being formed of a different material than the barrel.
A firearm assembly, comprising:
- a stock;
- a receiver coupled to the stock, the receiver configured to receive an ammunition cartridge;
- a chamber body coupled to the receiver, the chamber body having a chamber configured to receive the ammunition cartridge from the receiver and to securely position the ammunition cartridge for firing, the chamber having an exit opening configured to allow a bullet from the ammunition cartridge to pass through the exit opening;
- a barrel having a throat end coupled to the chamber body, a throat region disposed within the throat end of the barrel, and a bore extending away from the throat region to a muzzle end of the barrel spaced apart from the throat end, the bore being configured to allow the bullet from the ammunition cartridge to pass through the bore and to exit through a discharge opening proximate the muzzle end;
- and
- a throat insert disposed within the throat region of the barrel, the throat insert including an insert passage substantially aligned with the exit opening of the chamber and substantially aligned with the bore of the barrel, the insert passage being configured to allow the bullet from the ammunition cartridge to pass through the insert passage and into the bore, the throat insert being formed of a different material than the barrel.
