This disclosure relates to stock assemblies and, more particularly, to foldable stock assemblies for use on firearms.
BACKGROUNDFirearms are tool designed for a unique purpose. And just like with other type of tool, the convenience/usability/accuracy of a firearm is highly important. Accordingly, firearms often employ enhanced features that are designed to bolster their convenience/usability/accuracy. Accordingly, firearms often employ optics (e.g., halo sights, traditional scopes) to enhance their accuracy. Further, pistol grips may be utilized for enhance control and accessory rails may enhance usefulness. Additionally, firearms may include a foldable stock assembly to allow for compact storage and use as a pistol.

The butt stock portion includes a bolt retention receptacle configured to releasably receive a bolt handle of a bolt assembly when the butt stock is positioned in a first folded position.
One or more of the following features may be included. The butt stock portion may be configured to allow for a length of pull adjustment. The butt stock portion may be configured to allow for a cheek weld adjustment. A latch assembly may be configured to releasably lock the hinge assembly in a non-folded position. A catch assembly may be configured to releasably hold the butt stock portion in the first folded position. The butt stock portion may be a synthetic butt stock portion. The bolt retention receptacle may be configured to impede rearward motion of the bolt assembly when the bolt handle is positioned within the bolt retention receptacle.
In another implementation, a folding stock assembly for a firearm includes a butt stock portion; a receiver interface portion; a hinge assembly configured to allow the butt stock portion to pivot with respect to the receiver interface portion; and a catch assembly configured to releasably hold the butt stock portion in a first folded position.

A catch assembly may be configured to releasably hold the butt stock portion in the first folded position. The butt stock portion may be a synthetic butt stock portion.
The bolt retention receptacle may be configured to impede rearward motion of the bolt assembly when the bolt handle is positioned within the bolt retention receptacle. The receiver assembly may be a bolt action receiver assembly.
The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features and advantages will become apparent from the description, the drawings, and the claims.
Like reference symbols in the various drawings indicate like elements.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSReferring to
Butt stock portion 20 of folding stock assembly 18 may be configured to allow for a length of pull adjustment. For example, butt stock portion 20 may include shoulder interface 26 which may be longitudinally displaceable (in the direction of arrow 28) via e.g. one or more rods assemblies 30, 32 that may be slidably attached to main body 34 of butt stock portion 20. For example, through the use of shoulder interface 26, the distance between the shoulder of the user (not shown) of firearm 10 and trigger assembly 36 of firearm 10 may be adjusted, thus allowing for more comfortable and/or efficient use of firearm 10.
Further, butt stock portion 20 of folding stock assembly 18 may be configured to allow for a cheek weld adjustment. For example, butt stock portion 20 may include cheek interface 38 (shown in phantom), which may be latitudinally displaceable (in the direction of arrow 40), thus allowing the user (not shown) of firearm 10 to latitudinally position their eye behind a sighting device (such a holographic site, a scope, or iron sights, not shown).
Depending upon the manner in which butt stock portion 20 is constructed, butt stock portion 20 may be constructed of an organic material (e.g. wood) or may be constructed of a synthetic material (e.g. fiberglass-reinforced plastic)
As discussed above, firearm 10 may include receiver assembly 16 which may be coupled to barrel assembly 12. Accordingly, receiver interface portion 22 may be configured to couple receiver assembly 16 to folding stock assembly 18. For example, receiver interface portion 22 may be configured to be rigidly affixed to receiver assembly 16 via e.g. one or more threaded fasteners (not shown).
Bidirectional hinge assembly 24 may be configured to allow butt stock portion 20 to bidirectionally pivot with respect to receiver interface portion 22. Specifically,

While bolt retention receptacle 150 is described above as capturing bolt handle 152 whenever butt stock portion 20 is positioned on the right side of firearm 10, this is for illustrative purposes only and is not intended to be a limitation of this disclosure. For example, if firearm 10 is configured such that bolt handle 152 is positioned on the left side of firearm 10, bolt retention receptacle 150 may be configured to capture bolt handle 152 whenever butt stock portion 20 is positioned on the left side of firearm 10.
Having thus described the disclosure of the present application in detail and by reference to embodiments thereof, it will be apparent that modifications and variations are possible without departing from the scope of the disclosure defined in the appended claims.
