A [[gun|firearm]] buttstock that [b]can be folded[/b] while not in use, reducing the weapon's overall length for easier storage or transport. It usually utilizes a hinged attachment to the receiver.

It is a prominent feature of modern [[weapon|small arms]] design. Most folding stocks fold to the side, while few models fold to the top (e.g. [[SPAS-12]]) or bottom (e.g. [[MP40]]).
