Abstract

A collapsible rifle stock which provides a significantly shorter and more compatible stock designs. The stock includes a recoil pad, a buffer tube assembly, a buffer-receiving cavity, a track, a locking mechanism, and a release mechanism. The buffer-receiving cavity traverses through the recoil pad to facilitate a short collapsed configuration for the stock. The track is adjacently connected to the recoil pad, oriented parallel to a central axis of the buffer-receiving cavity. The buffer tube assembly attaches the stock to the rifle. The buffer tube assembly is slidably engaged along the track to allow for relative movement. The locking mechanism in conjunction with the release mechanism allow the user to position the stock into a collapsed and an extended configuration. The locking mechanism is mechanically integrated in between the track and the buffer tube assembly. The release mechanism is mechanically integrated in between the track and the recoil pad.

Claims

1. A short collapsible rifle stock comprises:

a recoil pad;

a buffer tube assembly;

a buffer-receiving cavity;

a track;

a locking mechanism;

a release mechanism;

the buffer-receiving cavity traversing through the recoil pad;

the track being oriented parallel to a central axis of the buffer-receiving cavity;

the track being adjacently connected to the recoil pad;

the buffer tube assembly being slidably engaged along the track;

the locking mechanism being mounted on the buffer tube assembly and interacting with the track;

the release mechanism being mounted on the recoil pad and interacting with the track;

the buffer tube assembly comprises a tubular stock base, a buffer tube, and a spring assembly;

the spring assembly being concentrically positioned within the buffer tube;

the buffer tube being concentrically positioned within the tubular stock base;

the buffer tube being removably attached to the tubular stock base;

a central axis of the buffer tube being positioned along the central axis of the buffer-receiving cavity;

a plurality of recessions;

the plurality of recessions being radially and externally distributed about the buffer tube; and

each of the plurality of recessions laterally traversing into the buffer tube.

2. The short collapsible rifle stock as claimed in claim 1 comprises:

the spring assembly comprises an inner spring, an outer spring, and a spring adaptor;

the spring adaptor comprises a cylindrical body, a support lip, and a spring-receiving cavity;

the spring-receiving cavity traversing into the cylindrical body;

the support lip being positioned opposite a first edge of the cylindrical body, across the cylindrical body;

the support lip being externally and annularly connected to the cylindrical body;

the inner spring being concentrically positioned within the spring-receiving cavity;

the outer spring being concentrically positioned about the cylindrical body; and

the outer spring being pressed against the support lip.

3. The short collapsible rifle stock as claimed in claim 1 comprises:

the buffer tube comprises a receiver-engaging tube and a supporting tube;

the receiver-engaging tube being concentrically aligned to the supporting tube;

the receiver-engaging tube being adjacently positioned to the supporting tube, opposite the buffer-receiving cavity; and

the receiver-engaging tube being removably attached to the supporting tube.

4. The short collapsible rifle stock as claimed in claim 3 comprises:

a receiver of a rifle; and

the receiver being removably attached to the receiver-engaging tube, opposite the supporting tube.

5. The short collapsible rifle stock as claimed in claim 1 comprises:

a first cavity;

a second cavity;

the track comprises a fixed bar and a pivot bar;

the pivot bar being pivotably connected to the recoil pad;

the fixed bar being adjacently connected to the recoil pad;

the fixed bar and the pivot bar being oriented parallel and offset to each other;

the first cavity and the second cavity each traversing through the tubular stock base of the buffer tube assembly, parallel to a central axis of the buffer tube assembly;

the first cavity and the second cavity being oriented parallel and offset to each other;

the pivot bar being slidably positioned within the first cavity; and

the fixed bar being slidably positioned within the second cavity.

6. The short collapsible rifle stock as claimed in claim 1 comprises:

the locking mechanism comprises a plurality of locking slots, a detent hole, and a spring-loaded detent;

the detent hole laterally traversing through the tubular stock base of the buffer tube assembly from a first cavity to a second cavity, the first cavity and the second cavity each traversing through the tubular stock base;

the plurality of locking slots being distributed along a pivot bar of the track, adjacent to a first end of the pivot bar;

each of the plurality of locking slots laterally traversing into the pivot bar;

the spring-loaded detent being positioned within the detent hole; and

the spring-loaded detent being selectively engaged with one of the plurality of locking slots.

7. The short collapsible rifle stock as claimed in claim 1 comprises:

the locking mechanism comprises a first channel, a second channel, a plurality of indentations, a detent hole, and a locking pin;

the detent hole laterally traversing through the tubular stock base of the buffer tube assembly from a first cavity to a second cavity, the first cavity and the second cavity each traversing through the tubular stock base;

the locking pin being slidably positioned within the detent hole;

the first channel laterally traversing into a pivot bar of the track, adjacent to a first end of the pivot bar;

the second channel laterally traversing into a fixed bar of the track, adjacent to a first end of the fixed bar;

each of the plurality of indentations laterally traversing into the fixed bar from the second channel;

the plurality of indentations being distributed along the second channel; and

the locking pin being selectively engaged with one of the plurality of indentations through the second channel.

8. The short collapsible rifle stock as claimed in claim 7, wherein a length of the locking pin is greater than a length of the detent hole.

9. The short collapsible rifle stock as claimed in claim 1 comprises:

a bore;

the bore being concentrically aligned with a first cavity, the first cavity being traversing through the tubular stock base;

the bore traversing into the recoil pad;

a second end of a pivot bar of the track being rotatably positioned within the bore;

the release mechanism comprises a crankpin, a U-shaped button, and a button-receiving cavity;

the crankpin being adjacently connected to the second end of the pivot bar, oriented parallel to the pivot bar;

the crankpin being positioned eccentrically from a main axis of the pivot bar;

a diameter of the crankpin being smaller than a diameter of the pivot bar;

the button-receiving cavity being positioned adjacent to the bore;

the button-receiving cavity laterally traversing into the recoil pad, perpendicularly intersecting the bore;

the crankpin being positioned within the bore and the button-receiving cavity;

the U-shaped button being tensionally mounted within the button-receiving cavity;

the crankpin being positioned within a receiving-channel of the U-shaped button; and
