Abstract

A receiver having an integral stock connector component that extends along the receiver; two extension rod/rail apertures formed through the integral stock connector component, wherein each extension rod/rail aperture is formed so as to slidably receive an extension rod/rail extending from a buttstock, such that each extension rod/rail is slidably movable within one of the extension rod/rail apertures; wherein each extension rod/rail comprises a rod channel and two or more rod dimples/detents formed along the rod channel; and a latch that is movable between an engaged position and a disengaged position, wherein when the latch is in the engaged position, a protrusion portion urges latch elements into the rod/rail apertures a distance that seats the latch elements into the rod dimples/detents, and wherein when the latch is in the disengaged position, the protrusion portion allows the latch elements to retract from the rod dimples/detents and into the rod channels.

wherein said latch extends from an engagement portion to a protrusion portion, wherein said latch is movable, along its longitudinal axis, between an engaged position and a disengaged position, wherein when said latch is in said engaged position, said protrusion portion urges at least one latch element into said rod/rail aperture a distance that allows each latch element to seat into said rod dimples/detents of each extension rod/rail, and wherein when said latch is in said disengaged position, said protrusion portion allows said at least one latch element to retract from said rod dimples/detents and into said rod channels of each extension rod/rail.

2. The receiver and collapsible buttstock of claim 1, wherein said integral stock connector component extends from said receiver such that at least a portion of said at least one extension rod/rail aperture is formed below said buffer tube aperture.

3. The receiver and collapsible buttstock of claim 1, wherein said integral stock connector component extends beyond said buffer tube attachment aperture of said receiver.

4. The receiver and collapsible buttstock of claim 1, wherein said integral stock connector component extend as far as said buffer tube attachment aperture of said receiver.

5. The receiver and collapsible buttstock of claim 1, wherein each extension rod/rail aperture is formed outside at least a portion of an exterior wall surface of said receiver.

6. The receiver and collapsible buttstock of claim 1, wherein each extension rod/rail aperture is formed at least partially within a receiving channel formed in an exterior wall surface of said receiver.

7. The receiver and collapsible buttstock of claim 1, wherein each extension rod/rail aperture is formed within said integral stock connector component and within at least a portion of a side wall of said receiver.

8. The receiver and collapsible buttstock of claim 1, wherein said extension rod/rail apertures are internally lined with a plastic, self-lubricating plastic, or other material to reduce friction between an interior wall of said extension rod/rail apertures and an exterior surface of each extension rod/rail.

9. The receiver and collapsible buttstock of claim 1, wherein each extension rod/rail aperture and each extension rod/rail has a substantially circular, square, triangular, rectangular, oblong, “

L”

shaped, “

I”

shaped, “

C”

shaped, “

V”

shaped, “

Z”

shaped, “

T”

shaped profile.

10. The receiver and collapsible buttstock of claim 1, further comprising a cheek rest that extends from a first end to a second end, wherein said cheek rest is permanently or releasably attached or coupled to said buttstock atop said top end of said buttstock, proximate said first end of said cheek rest, and wherein an aperture is defined between said recessed channel of said buttstock and an interior surface of said cheek rest, which allows a buffer tube to freely slide therethrough.

11. The receiver and collapsible buttstock of claim 1, wherein said cheek rest comprising a substantially inverted “

U”

or “

V”

shaped portion of material.

12. The receiver and collapsible buttstock of claim 1, wherein each extension rod/rail comprises a solid portion of material.

13. The receiver and collapsible buttstock of claim 1, wherein each extension rod/rail comprises a hollow or tubular portion of material.

14. The receiver and collapsible buttstock of claim 1, wherein each rod dimple/detent represents a lockable position of said buttstock relative to said receiver.

15. The receiver and collapsible buttstock of claim 1, wherein each latch element comprises a spherical ball, a cylindrical portion of material, a protrusion portion, or a rectangular latch.

16. The receiver and collapsible buttstock of claim 1, further comprising at least one biasing element positioned between said latch and an interior surface of said latch cover cavity, so as to bias said latch to said engaged position.

17. A receiver and collapsible buttstock, comprising:

an integral stock connector component that extends from said receiver;

at least one extension rod/rail aperture formed through said integral stock connector component, wherein said at least one extension rod/rail aperture is formed so as to slidably receive an extension rod/rail extending from a buttstock, such that said extension rod/rail is slidably movable within said at least one extension rod/rail aperture;

wherein said buttstock comprises a recessed channel formed in an upper portion of said buttstock;

wherein a rod channel is formed along at least a portion of said at least one extension rod/rail, wherein said rod channel includes a rod dimple/detent formed at each terminating end of said rod channel; and

a latch cover attached or coupled to said integral stock connector component, wherein said latch cover includes interior side walls defining a latch cover cavity, wherein said latch cover cavity extends to at least one rod/rail aperture formed therethrough, wherein said at least one rod/rail aperture is formed so as to be aligned with said at least one extension rod/rail aperture and to slidably receive said at least one extension rod/rail;

wherein said latch extends from an engagement portion to a protrusion portion, wherein said latch is movable, within said latch cover cavity, along its longitudinal axis, between an engaged position and a disengaged position, wherein when said latch is in said engaged position, said protrusion portion urges a latch element into said at least one rod/rail aperture a distance that seats said at least one latch element into said rod dimples/detents of said at least one extension rod/rail, and wherein when said latch is in said disengaged position, said protrusion portion allows said at least one latch element to retract from said rod dimples/detents and into said rod channel of said at least one extension rod/rail.
