Easy connect stock and forend system

Abstract

A method and apparatus are disclosed for substituting a different stock, and a forend assembly, in a long gun (e.g., a shotgun) without the use of tools by a user in the field. Applicants' preferred apparatus for substituting a stock comprises: a long gun (e.g., an illustrated shotgun) having a stock and a receiver assembly; and an adaptor which removably interconnects the stock to the receiver assembly, wherein the adaptor includes: an adaptor base bolted to the receiver assembly; and a tool-less stock release means slidably attached to the base, whereby the stock release can be lifted up by a user to release the stock from the adaptor. Upon a new stock being placed in the adaptor, the stock release means can be pushed down, back into the adaptor base, to lock the adaptor, whereupon the adaptor interconnects the substitute stock with the receiver assembly. Applicants' preferred forend assembly comprises: a modified forend carrier that is affixed to the long gun (e.g., the illustrated shotgun); and a forend which removably mounts onto the fixed carrier by a tool-less forend release means attached to the forend and carrier, wherein the tool-less forend release means comprises a tongue-and-groove arrangement and a releasable lock. This permits the forend to be swapped out.

Description

RELATED APPLICATION [0001] This application claims priority from a U.S. Provisional Patent Application, Ser. No. 60 / 729,145, filed Oct. 20, 2005.FIELD OF INVENTION [0002] This invention relates generally to firearms. More specifically, it relates to the stock and forend attachment for long guns, such as shotguns. BACKGROUND [0003] A long gun is a firearm with an extended barrel, usually designed to be fired braced against the shoulder. Barrels of such weapons commonly extend to around 50 cm or longer, giving considerable accuracy and range. Most modern long guns fall into one of two categories, rifles or shotguns, distinguished by their design and type of projectile they fire. [0004] Shotguns are designed primarily to fire small pellets, called shots. Some shotguns can be adapted to fire a single projectile, called a slug. [0005] There are several major components of shotguns: the barrels, stocks, and forends or forearms. Shotguns are distinguished by the length of their barrels, an...

Benefits of technology

[0023] An easy connect / disconnect apparatus is disclosed for replacing a stock or forend (a.k.a. forearm) in a long gun without the use of tools in the field. Applicants' preferred and illustrated embodiment comprises: a modified stock having a specially shaped end adjacent a standard receiver assembly of a shotgun; the receiver assembly has an adaptor that interconnects the stock to the receiver assembly to hold the shotgun together; wherein the adaptor has a tool-less stock release that can be lifted to release the stock from the adaptor and receiver assembly. In the field a shooter can unlock the adaptor without any tools to substitute a different stock. Upon locking the adaptor, again without any tools, the receiver and new stock are secured together. Applicants' preferred embodiment also provides a forend that can be mounted or replaced by a pushbutton release.

Problems solved by technology

One of the shooters will, more than likely, have an improper fit with the shotgun.

The changing of the stock, forend, or both is a time-consuming process.

If the stock is too long, it can get caught in the armpit of the user.

If the stock is too short, recoil can cause the scope to hit the eyebrow.

An improper fit can also cause during the gun's recoil: the stock to hit the cheek, when the cheek is pressed on the stock to line up the sight and target.
