Abstract
A firearm barrel and a method for manufacturing the same are disclosed. In some embodiments, a barrel for a firearm may be provided. The barrel may comprise a chamber, an entire geometry of which is formed to a final depth. After providing the barrel with the entire geometry of the chamber being formed to the final depth, a material modification process that modifies one or more properties of the barrel may be performed. After performing the material modification process, a composite matrix wrapping that surrounds an outer circumference of the barrel over a length of the barrel may be applied.
Claims18
A method for manufacturing a firearm barrel, the method comprising:
- providing a barrel for a firearm;
- forming, within the barrel, a chamber configured to hold an ammunition cartridge, wherein an entire geometry of the chamber, including an interior of the chamber, is formed to a final depth within the barrel through the forming;
- after forming the chamber within the barrel with the entire geometry of the chamber being formed to the final depth, performing a material modification process that modifies one or more metallurgical properties of the barrel, wherein no further material is cut away from the interior of the chamber by machining after the material modification process is complete;
- after performing the material modification process, applying a composite matrix wrapping that surrounds an outer circumference of the barrel over a length of the barrel;
- and
- after the composite matrix wrapping is applied, processing the barrel so as to form a receiver interface onto a portion of an outer surface of the barrel, the receiver interface at least partially overlapping the chamber in a transverse direction.
A firearm barrel comprising:
- a barrel having a chamber formed therein configured to hold an ammunition cartridge, the chamber comprising an interior, the chamber extending longitudinally through an interior portion of the barrel, and one or more metallurgical properties of the barrel being modified by a material modification process that is performed on the barrel after the chamber is formed, wherein no further material is cut away from the interior of the chamber by machining after the material modification process is complete, and a receiver interface formed onto a portion of an outer surface of the barrel, the receiver interface at least partially overlapping the chamber in a transverse direction;
- and
- a composite matrix wrapping that surrounds an outer circumference of the barrel over a length of the barrel, wherein the composite matrix wrapping is applied to the barrel after the material modification process is performed,
- wherein an entire geometry of the chamber is formed to a final depth prior to the material modification process being performed,
- wherein the barrel is processed so as to form the receiver interface after the composite matrix wrapping is applied.
