Abstract

A takedown firearm stock and related methods are disclosed. The takedown firearm stock has a buttstock assembly comprising a magazine release; a first accessory mounting interface; a forend assembly comprising a recess for receiving a barrel having a barrel shank, and a release mechanism for removably coupling the forend assembly and the buttstock assembly, and one of: an attachment bracket or a barrel tray configured to support the barrel, the attachment bracket or the barrel tray comprising the first accessory mounting interface. When the forend assembly is coupled to the buttstock assembly in a deployed configuration, the forend assembly releasably couples to the buttstock assembly at a forend-to-stock interface, and when the forend assembly is coupled to the buttstock assembly in a stowed configuration, the forend assembly releasably couples to an underside of the buttstock assembly.

First claim

What is claimed is:

1. A takedown firearm stock, comprising:
a buttstock assembly comprising a magazine release;
a first accessory mounting interface;
a forend assembly comprising a recess for receiving a barrel having a barrel shank, and wherein the forend assembly further comprises:
a release mechanism for removably coupling the forend assembly and the buttstock assembly, and one of:
an attachment bracket configured to support the barrel, the attachment bracket comprising the first accessory mounting interface, or
a barrel tray removably coupled to the forend assembly, the barrel tray comprising a barrel channel configured to receive and interface with the barrel, wherein the barrel channel is unitary with or coupled to the first accessory mounting interface;

wherein
when the forend assembly is coupled to the buttstock assembly in a deployed configuration, the forend assembly releasably couples to the buttstock assembly at a forend-to-stock interface, and the barrel shank couples to a receiver of the takedown firearm, and
when the forend assembly is coupled to the buttstock assembly in a stowed configuration, the forend assembly releasably couples to an underside of the buttstock assembly.

2. The takedown firearm stock of claim 1 , wherein the buttstock assembly further comprises a grip and a recess for providing a clearance for the barrel, and an aperture shaped to partially enclose and protect the barrel shank of the barrel,
and when the forend assembly is coupled to the buttstock assembly in the deployed configuration, the forend assembly is positioned to support the barrel in a longitudinal firing position,
and when the forend assembly is coupled to the buttstock assembly in the stowed configuration, the aperture of the buttstock assembly is shaped to partially enclose and protect the barrel shank, and the forend assembly is positioned to nest in a storage cavity on the underside of the buttstock assembly.

3. The takedown firearm stock of claim 1 , wherein the barrel tray is configured to couple to the forend assembly upon application of pressure, or wherein the barrel tray is coupled to the forend assembly using an attachment mechanism comprising one or more fasteners.

4. The takedown firearm stock of claim 1 , wherein the first accessory mounting interface comprises one or more elongated slots configured to receive one or more mounting rails for mounting one or more accessories, or configured to receive one or more accessories.

5. The takedown firearm stock of claim 1 , wherein at least one of a weight density, a strength, or a rigidity or stiffness of a material used to form the first accessory mounting interface is greater than that of a material used to form a respective one of the forend assembly or the buttstock assembly.

6. The takedown firearm stock of claim 1 , wherein the barrel channel comprises one or more cutouts shaped and positioned to allow air flow through one or more elongated slots of the first accessory mounting interface.

7. The takedown firearm stock of claim 1 , wherein the magazine release comprises a shaft, a fastener arranged perpendicular to and passing through the shaft, and a first button configured to be installed within a first cutout on a first side of the buttstock assembly, wherein the first button is configured to enable release of a magazine from a magazine well of the takedown firearm when depressed.

8. The takedown firearm stock of claim 7 , wherein the shaft comprises a keying feature to: prevent rotation of the first button within the first cutout on the first side of the stock assembly, prevent rotation of the first button with respect to a second button, the second button configured to be installed within a second cutout on a second opposing side of the buttstock assembly, or a combination thereof.

9. The takedown firearm stock of claim 8 , wherein the first button is unitary with or coupled to the shaft, and wherein the keying feature comprises a flat section having a rectangular end on the shaft, the rectangular end configured to mate with a recess in the second button, and wherein the fastener passes through one or more of an aperture in the second button and an aperture in the rectangular end.

10. The takedown firearm stock of claim 1 , wherein the forend assembly further comprises one or more accessory recesses shaped to accept at least the first accessory mounting interface, and wherein one or more second accessory mounting interfaces partially extend through the one or more accessory recesses, the one or more second accessory mounting interfaces accessible from one or more sides of the forend assembly.

11. The takedown firearm stock of claim 1 , wherein at least a portion of the first accessory mounting interface protrudes through an accessory recess in the forend assembly and is configured to receive one or more mounting rails for mounting one or more accessories, or configured to receive one or more accessories.

12. The takedown firearm stock of claim 1 , wherein the barrel tray comprises one or more reinforcing ribs shaped and positioned on a supporting wall of the barrel tray, wherein the supporting wall connects the barrel channel to the first accessory mounting interface.

13. A method, comprising:
providing a buttstock assembly, and a forend assembly for a takedown firearm, wherein the forend assembly is removably couplable to the buttstock assembly in a deployed configuration and a stowed configuration;
providing a release mechanism for removably coupling the forend assembly and the buttstock assembly, the release mechanism comprising a release button and a detent engagement, the release button configured to release the detent engagement when depressed;
providing a recess and a barrel tray in the forend assembly for receiving a barrel having a barrel shank, wherein the barrel tray is configured to interface with the barrel;
providing a first accessory mounting interface unitary with or coupled to the barrel tray;
providing a magazine release having a keying feature, and at least one button, wherein the at least one button is configured to enable release of a magazine from a magazine well of the takedown firearm when depressed;
coupling the forend assembly to the buttstock assembly in the deployed configuration, the barrel shank of the barrel configured to couple to a receiver of the takedown firearm; and
coupling the forend assembly to the buttstock assembly in the stowed configuration, wherein the forend assembly is coupled to an underside of the buttstock assembly.

14. A takedown firearm, comprising:
an action assembly;
a barrel having a barrel shank;
a magazine release;
a buttstock assembly;
a first accessory mounting interface;
a forend assembly comprising a recess for receiving the barrel, and wherein the forend assembly further comprises:
a release mechanism for removably coupling the forend assembly and the buttstock assembly, and one of:
an attachment bracket configured to support the barrel, the attachment bracket comprising the first accessory mounting interface, or
a barrel tray removably coupled to the forend assembly, the barrel tray comprising a barrel channel configured to receive and interface with the barrel, wherein the barrel channel is unitary with or coupled to the first accessory mounting interface; wherein

when the forend assembly is coupled to the buttstock assembly in a deployed configuration, the forend assembly releasably couples to the buttstock assembly at a forend-to-stock interface, and the barrel shank is configured to couple to the action assembly, and
when the forend assembly is coupled to the buttstock assembly
