Abstract

An apparatus for an anti-rattle assembly for a collapsible buttstock for a firearm may include a baseplate with a plurality of lower guides and a plurality of fasteners wherein the plurality of fasteners removably secure the anti-rattle assembly to a plurality of fastener positions of a buttstock body. The anti-rattle assembly may further include a pressure plate with one or more ridges to engage one or more rail surfaces of a receiver extension and a plurality of upper guides and a plurality of biasing members wherein the pressure plate is vertically aligned with the baseplate and the plurality of biasing members are coupled between the upper guides and the lower guides and bias the one or more ridges against the one or more rail surfaces. The anti-rattle assembly restricts the movement of the receiver extension in a tubular aperture of the buttstock body.

4. The anti-rattle assembly of claim 1, wherein the plurality of biasing members include at least one of the following, a spring, a compressible foam, a compressible gel, or a fluid.

5. The anti-rattle assembly of claim 1, wherein the baseplate further comprises a plate aperture to allow a locking pin to slideably couple with the baseplate.

6. The anti-rattle assembly of claim 5, wherein the baseplate further comprises a lower pin biasing guide for a pin biasing spring, the pin biasing spring applying a biasing for on the locking pin.

7. A method of reducing movement in a collapsible buttstock, comprising:

applying pressure on a receiver extension inserted into a tubular aperture of a buttstock body by using an anti-rattle kit comprising;

a baseplate with a plurality of lower guides and a plurality of fasteners wherein the plurality of fasteners removably secure the anti-rattle kit to a plurality of fastener positions of the buttstock body;

a pressure plate with one or more ridges to engage one or more rail surfaces of the receiver extension and a plurality of upper guides; and

a plurality of biasing members wherein the pressure plate is vertically aligned with the baseplate and the plurality of biasing members are coupled between the plurality of upper guides and the plurality of lower guides and bias the one or more ridges against the one or more rail surfaces;

aligning an upper tube portion of the receiver extension with an upper body portion of the tubular aperture with the applied pressure to reduce a movement of the buttstock body in relation to the receiver extension; and

maintaining the alignment a tubular axis of the buttstock body with a firearm axis.

8. The method of reducing movement of claim 7, wherein the buttstock body further comprises one or more upper stops and wherein the pressure plate comprises one or more lower stops that engage the one or more upper stops to restrict the pressure of the one or more ridges against the one or more rail surfaces.

9. The method of reducing movement of claim 7, wherein the plurality of fasteners include at least one of the following, a barb fastener, a clip fastener, a rivet, a screw, a bolt and nut, an expansion bolt, a cantilever hook, a spring toggle, a turnbuckle, a pine in hole, a wedge in slot, a trap, a snap, a ball and socket, a cantilever spring, a crush rib, welding, brazing, solvent bonding, Velcro, a crimp, or a seam, and wherein the plurality of fastener positions include at least one of the following, an fastener aperture operable to receive the plurality of fasteners or a solid blank.

10. The method of reducing movement of claim 7, wherein the plurality of biasing members include at least one of the following, a spring, a compressible foam, a compressible gel, or a fluid.

11. The method of reducing movement of claim 7, wherein the baseplate further comprises a plate aperture to allow a locking pin to slideably couple with the baseplate.

12. The method of reducing movement of claim 11, wherein the baseplate further comprises a lower pin biasing guide for a pin biasing spring, the pin biasing spring applying a biasing for on the locking pin.
