Stocks for aimable devices are provided. In one aspect, stock has a body mechanically associated with the aimable device and movable to determine an aiming axis of the aimable device, a shoulder mount positioned proximate to one end of the body, a firing grip positioned apart from the shoulder mount along a length of the body; a support leg having a mounting end pivotably mounted to the body between the firing grip and an end of the body opposite from the shoulder mount and having a foot end movable between a first range of positions and a second range of positions and a receiver located between the mounting of the support leg to the body and the firing grip and adapted to releasably hold the support leg in the first range of positions wherein the at least one support leg provides a grippable forestock.

An interface for coupling a bipod to a sling stud of a firearm forend. The interface can include two pawls that pivot to release or grasp the sling stud. The pawls can be biased upward via a detent that rides within a vertical aperture in a pivot holder. The pivot holder can move up and down within a vertical aperture in a mounting plate of the interface, and via this movement the pawls may be forced open or closed. A bottom surface of one or both pawls can include an irregular surface different portions of which interface with a top of the detent depending on a vertical position of the pivot holder within the aperture in the mounting plate.

A bipod assembly includes a first yoke configured to be attached to a firearm. A second yoke is pivotably attached to the first yoke. Right and left legs are pivotably connected to the second yoke and movable between an open position and a closed position. The bipod assembly is movable between a stowed and locked position, a stowed and unlocked position, a deployed and unlocked position, and a deployed and locked position. In a locked position, part of each leg engages the first yoke to maintain the leg's open or closed position as well as the leg's deployed or stowed position. The bipod assembly enables one-hand deployment from a stowed state.

A mounting rail can be added to an air rifle by clamping a clamp to the air cylinder of the air rifle. The clamp has a monolithic clamp body that includes the mounting rail, a base, a left jaw and a right jaw. The left and right jaws are attached to the base. A clamp actuator can draw the jaws together to clamp onto the air cylinder. The base can include a mounting rail such as a Picatinny rail. As such, clamping the monolithic clamp body onto the air cylinder adds a mounting rail to the air rifle.

An accessory mounting interface for a firearm, and a related method, are disclosed. The interface has a firearm accessory, a first elongated fastener, and a second fastener rotationally mated to the first elongated fastener. The first elongated fastener has right-handed threading and is arranged through a through hole in the firearm accessory with a first end extending below first and second halves of a first slot protrusion of the firearm accessory. The second fastener has a length greater than a width, the length measured along a longitudinal axis of the second fastener, the second fastener having a plurality of straight edges. At least one of the plurality of straight edges prevents the second fastener from rotating further than a closed position when the at least one of the straight edges abuts a sidewall of an elongated slot in the firearm.
