Abstract

A buttstock assembly configured to work in conjunction with a compact buffer assembly consisting of a buffer tube, spring and bolt carrier with an integral buffer is provided. The buttstock assembly, buffer tube and bolt carrier are configured to work with AR15/M16 type firearms and their derivatives. By incorporating the buffer onto the bolt carrier, which is used in conjunction with a buffer tube of reduced length, the overall length of the host firearm is reduced by approximately 3.2 inches. No permanent modification need be made to the host firearm in order to utilize the compact buffer assembly and buttstock assembly disclosed herein.

First claim

What is claimed is:

1. A buttstock assembly for use with a gas operated firearm comprising:
shoulder stock;
two guide rods with notches; and
a housing comprising an exterior and an interior with said interior defining a longitudinally extending circular bore sized to receive a buffer tube comprising circumferential ridges that contact an interior of said longitudinally extending circular bore; said housing having a forward face comprising a protrusion to engage an opening on a lower receiver of said gas operated firearm; said housing defining three openings, wherein one of said three openings is sized to allow passage of a threaded portion of a buffer tube and said one of said three openings is smaller in diameter than said longitudinally extending circular bore thereby creating an internal shoulder between said opening and said longitudinally extending circular bore, wherein said internal shoulder rests against a forward face of one of said circumferential ridges, and wherein two of said three openings are smaller openings to receive and support a portion of a guide rod;
wherein said shoulder stock is mated with said two guide rods, which are mated with said housing to form a portion of said buttstock assembly.

2. The buttstock assembly of claim 1 , wherein said housing comprises an exterior with a cheek piece contoured and shaped into a surface of said exterior.

3. The buttstock assembly of claim 1 , wherein said housing comprises a bottom side which comprises a placement with a placement opening, wherein said placement opening houses a spring biased catch to operate said buttstock assembly.

4. The buttstock assembly of claim 3 , wherein said placement opening is transverse to a longitudinal axis of said longitudinally extending circular bore of said housing.

5. The buttstock assembly of claim 4 , wherein said placement opening is in communication with a roll pin opening that is sized to and comprises a roll pin.

6. The buttstock assembly of claim 5 , wherein said spring biased catch comprises:
two openings and a cylindrical body portion extending between said two openings; and
a bore configured to receive said roll pin.

7. The buttstock assembly of claim 6 , wherein said cylindrical body comprises two ends, wherein in one end is a distal end and one end is a pressure pad.

8. The buttstock assembly of claim 6 , wherein each of said two openings of said spring biased catch comprise one side defining a detent portion, wherein said detent portion is engaged with said notches on said guide rods.

9. The buttstock assembly of claim 8 , wherein the shoulder stock comprises a front side and a back side, and a bore extending between said front and back side.

10. The buttstock assembly of claim 9 , wherein said bore defines a circular opening configured to receive a portion of said buffer tube.

11. The buttstock assembly of claim 10 , wherein the shoulder stock is made from aluminum, polymers, or metals.

12. The buttstock assembly of claim 11 , wherein said front side comprises two openings, wherein each is mated with a back end of a guide rod.

13. The buttstock assembly of claim 1 , wherein said guide rods are elongated and circular.

14. The buttstock assembly of claim 13 , wherein said guide rods each have two semicircular notches along one side.

15. The buttstock assembly of claim 14 , wherein said guide rods each has a bore that runs transverse to a longitudinal axis of each said guide rod, wherein said bore is located toward a back end of said guide rod and is configured to receive a roll pin.

16. The buttstock assembly of claim 15 , wherein a portion of each guide rod's rearward end is received within a different of two bores in a front side of said shoulder stock.

17. The buttstock assembly of claim 16 , wherein said shoulder stock has an opening on each side of said shoulder stock; and wherein each opening is aligned with one of each said bore that runs transverse to a longitudinal axis of each said guide rod and a roll pin is received through the aligned bores.
