    摘要： 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.
