Abstract

In one aspect, a retractable buttstock may include a buttpad that allows the user to rest the weapon on their shoulders; a pair of extension rods; a buffer tube that allows the buttstock to attach to the firearm; and a buffer tube housing to receive the buffer tube. In an exemplary embodiment, the extension rods are hollow and a resilient unit is received in each extension rod. The extension rods have a pair of first positioning grooves and a pair of second positioning grooves to engage with stoppers of the buffer tube housing. The buttstock can be fully-extended and collapsed depending on whether the stoppers engage with the first or second positioning grooves. It is noted that the user can operate the retractable buttstock with one hand.

Claims

1. A retractable buttstock for a firearm that is configured to transition from a collapsed position and a fully-extended position and vice versa comprising:

a buttpad that allows a user to rest the firearm on his/her shoulder;

a pair of extension rods;

each extension rod receiving a resilient unit; and

a buffer tube housing having a release button,

wherein the buttpad has a first pair of receiving holes, and each first pair receiving hole is configured to receive one end of each extension rod;

the buffer tube housing also has a second pair of receiving holes, and each second pair receiving hole is configured to movably receive the other end of each extension rod;

wherein the extension rods have one or more pairs of positioning grooves, including a pair of first positioning grooves closer to the first receiving holes and a pair of second positioning grooves closer to the second receiving holes;

each of the first positioning grooves is located at a substantially similar position on each extension rod while each of the second positioning grooves is located at a substantially similar position on each extension rod;

wherein the release button has a pair of stoppers corresponding to the first and second positioning grooves;

the buttstock reaches the collapsed position when the stoppers of the release button engage with the first positioning grooves while the buttstock reaches the fully-extended position when the stoppers engage with the second positioning grooves.

2. The retractable buttstock for a firearm of claim 1, further comprising a buffer tube that allows the buttstock to attach to the firearm.

3. The retractable buttstock for a firearm of claim 1, wherein the release button is pressed to disengage the stoppers with the second positioning grooves and an external force has to be applied to the buttpad to compress the resilient units in the extension rods to collapse the buttstock until the stoppers engage with the first positioning grooves.

4. The retractable buttstock for a firearm of claim 2, wherein the release button is pressed to disengage the stoppers with the second positioning grooves and an external force has to be applied to the buttpad to compress the resilient units in the extension rods to collapse the buttstock until the stoppers engage with the first positioning grooves.

5. The retractable buttstock for a firearm of claim 1, wherein the release button is pressed to disengage the stoppers with the first positioning grooves and the buttpad is automatically pushed away from the buffer tube housing by a resilient force exerted by the resilient units until the stoppers engage with the second positioning grooves.

6. The retractable buttstock for a firearm of claim 2, wherein the release button is pressed to disengage the stoppers with the first positioning grooves and the buttpad is automatically pushed away from the buffer tube housing by a resilient force exerted by the resilient units until the stoppers engage with the second positioning grooves.

7. The retractable buttstock for a firearm of claim 4, wherein the release button is pressed to disengage the stoppers with the first positioning grooves and the buttpad is automatically pushed away from the buffer tube housing by a resilient force exerted by the resilient units until the stoppers engage with the second positioning grooves.

8. The retractable buttstock for a firearm of claim 4, wherein the extension rods include a pair of third positioning grooves to engage with the stoppers to secure the buffer tube housing between the first and second positioning grooves.
