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.

• F41A 21/02 - Composite barrels, i.e. barrels having multiple layers, e.g. of different materials
• F41A 21/12 - Cartridge chambersChamber liners
• F41A 21/48 - Barrel mounting means, e.g. releasable mountings for replaceable barrels

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 system also includes a sealing member positioned within channels in the barrel and the chamber body. The chamber body and/or the barrel may be changed on the firearm at any time based on the preference of the end user.
