Abstract: A buttstock includes a mounting extension member attachable to a firearm receiver, an adjustable butt pad for varying the length of the stock, and an adjustable cheek rest for adjusting the height of the stock. The butt pad assembly is attached to the extension member by a laterally compressible clamping member operated by a double-acting cam lever having two locking surfaces and a non-locking release surface. At least one adjustment rail extends forward from the butt pad through opposing movable jaws of the clamping member. The rail can slide forward/rearward to adjust the stock length which is lockable via the cam lever locking surfaces. The cheek rest includes compressible opposing adjustment legs operated by a similarly configured cam lever in one embodiment. The height of the cheek rest may be adjusted and locked in position in a similar manner.
