Problems solved by technology

However, previous modular gunstocks present a number of difficulties.
The first of which is that the mounting components for such systems tends to be bulky, as they contain additional mounting features not present in other stocks.
Second, a structural failure in a mounting component tends to render the weapon useless until a costly part is replaced.
Particular problems with such systems include lack of stability, insufficient strength, and cheek weld disruption where the pieces join.

Embodiment Construction

[0056]With reference now to the drawings, the preferred embodiment of the modular gunstock is herein described. It should be noted that the articles “a”, “an”, and “the”, as used in this specification, include plural referents unless the content clearly dictates otherwise.

[0057]With reference to FIGS. 1 and 2, the modular gunstock comprises three main components. The first is a weapon mounting structure 12 which is the actual attachment to the weapon (See, FIG. 3). In the case of an AR15 / M16 model weapon, the structure is actually a replacement receiver extension tube. However the only requirement is that the mounting structure 12 be cylindrical (either round or polygonal) so that sleeve module 14 may slide over it. As such, references to the mounting structure 12 as being an extension tube should be construed as only relating to this preferred and disclosed embodiment as alteration of the structure for other weapon platforms that do not need a receiver extension tube will be obviou...

Abstract

The present invention is a modular gunstock utilizing a two-piece mounting structure and a stock module. The structure comprises a weapon attachment, in the case of an AR15 / M16 rifle a receiver extension tube, and a sleeve slidable over said attachment and containing mounting structure for the stock module. The disclosed stock module is adjustable for length and features a length pre-set system, a latch with independent dual-pawls and an integrated impact buffer, modular tailpiece, and storage. The sleeve also features a position selectable fixed cheek plate.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims priority on prior filed U.S. Provisional Application No. 60 / 889,244, filed Feb. 9, 2007 and incorporates the same by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to the field of firearms and more particularly relates to a gunstock with enhanced modularity and adjustment functions.BACKGROUND OF THE INVENTION[0003]Gunstocks or “buttstocks” as they are commonly known, are well known in the art of firearms. These devices have been used with “long arms” as a means for resting and securing the weapon against the shoulder of the user when firing. Gunstocks have also been used as a weapon in and of themselves in a melee fight. As such, gunstocks have been developed along many different shapes and designs and using various materials to increase durability, reduce the effects of recoil, or “kick”, provide adjustability and customization, increase shooter accuracy, provide storage for g...
