Firearm adjustable length stock assembly

Abstract

A stock assembly and related method are provided. The stock assembly can include a base that can be joined with a weapon and a butt portion that movably extends from the base so the stock assembly can be adjusted in length. The stock can include an adjustment limiter configured to stop extension of the butt portion at a predetermined length, which can be set by a user to fit their stature. The butt portion can include a longitudinal axis and a limiter surface offset at an angle relative to the axis. The adjustment limiter can be a wedge that wedges against the limiter surface to set the stock assembly at the predetermined length, thereby automatically setting that length in a consistent and repeatable manner. A lock, separate from the adjustment limiter, can selectively lock the butt portion in a fixed position as or after the stock assembly attains the predetermined length.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to firearms, and more particularly to an adjustable length stock assembly for a firearm.[0002]Many modern sporting and military firearms include a stock that extends rearward from the firearm. The stock typically includes a forward portion that connects to a receiver of the firearm, and a rearward portion that is shaped and distanced from the receiver of the firearm so that a user can engage the rearward portion against the user's shoulder and stabilize the firearm. Some stocks are adjustable in length to accommodate individuals of different statures. Other stocks are foldable so that a user can fold the stock forward alongside or over the receiver. Adjustable length stocks typically include a lever or pin that a user manipulates to release a sliding portion of the stock. The user grasps the sliding portion and manually moves it to a desired position so that the stock is of a desired length. The user releases the lever o...

AI Technical Summary

Benefits of technology

The patent text describes a stock assembly for a weapon that allows for easy adjustment of its length. The assembly includes a bias element, such as a spring, to extend the length of the assembly, a lock to fix its length, and an adjustment limiter that can be set to a preferred position to automatically adjust the length. This allows users to quickly and easily adjust the length of the stock assembly to their stature and the weapon's needs.

Problems solved by technology

Although these types of adjustable stocks provide adequate adjustment, they are hard to manipulate because two hands are usually required to hold the pin and simultaneously slide the stock.

The use of two hands limits the positions in which the user can make the adjustment.

Many of these types of adjustable stocks also do not enable the user to deploy the stock to a desired length from a shorter length very quickly or consistently.
