A firearm stock is disclosed with an adjustable cheek riser, which includes an elevation mechanism and a cheek plate attached to a rising mechanism. In this manner, the cheek plate is adjustable in the vertical direction to provide fine adjustment to the height of the cheek plate with respect to the firearm stock. Aspects of the firearm stock include an adjustable stock that can provide adjustability for various firearms with regard to stock position and cheek plate position.

A stock assembly and related method are provided. The stock assembly can include a base that can be joined with a weapon and a butt portion that movably extends from the base so the stock assembly can be adjusted in length. The stock can include an adjustment limiter configured to stop extension of the butt portion at a predetermined length, which can be set by a user to fit their stature. The butt portion can include a longitudinal axis and a limiter surface offset at an angle relative to the axis. The adjustment limiter can be a wedge that wedges against the limiter surface to set the stock assembly at the predetermined length, thereby automatically setting that length in a consistent and repeatable manner. A lock, separate from the adjustment limiter, can selectively lock the butt portion in a fixed position as or after the stock assembly attains the predetermined length.

A stock for a gun is disclosed which includes a butt stock body (12). The butt stock body may include a butt plate receptacle (108). The stock further may include a butt plate assembly (20) positioned in the butt plate receptacle (108), a cheek piece (18) releasably secured to the butt stock body (12) and the butt plate assembly (20), and a clamp (30). The stock may include first and second configurations such that in the first configuration the clamp permits independent movement of the butt plate assembly (20) and the cheek piece (18), and in the second configuration the clamp fixes movement of the butt plate assembly and the cheek piece relative to the butt stock body. The clamp (30) may be assembled within the stock body (12) to provide for variable adjustment of the butt stock with a dominant hand on the firearm grip.

A buttstock of a small arm includes a front connection area for a positive connection to a receiver. In order to permit increased cartridge capacity, a trigger unit with a trigger latch and a transfer element extending forward for connection of the trigger latch to a trigger mechanism arranged in the receiver is positioned on the buttstock.

A triple-barrel firearm includes three barrels in a triangular array mounted on a rear stock. The rear stock is connected to the firearm rearward of the firearm's trigger assembly by a hinge assembly. The hinge assembly in turn, includes a locking member and a manually-activatable release member whereby the rear stock can be pivoted between a first “fire ready” position distal with respect to the trigger assembly and a second “storage” position proximal with respect to the trigger assembly. The locking member automatically locks the rear stock in the first position or the second position. The release member unlocks the locking member upon manual activation thereof to enable pivoting of the rear stock from the first position to the second position or vice versa. The rear stock further includes an opening for a retainer for firearm accessories.

The present disclosure describes a foldable firearm that collapses into a folded state under spring pressure. The foldable firearm may include a foldable grip assembly. The foldable grip assembly may include a foldable pistol grip, a foldable trigger assembly, a folding bar, and a foldable hand stop. The foldable grip assembly may fold into the top shell of the foldable firearm. The foldable firearm may also include an ambidextrous charging handle assembly that may include a bottom portion, a top portion, a guide bar, and two opposing charging handles. The charging handles may be pulled to unfold the foldable firearm, and/or butterflied such that pivoting one charging handle causes the other charging handle to pivot. The first-pivoted charging handle may then be pulled rearwards to unfold the firearm. The first-pivoted charging handle may then be pulled further rearwards to rack the slide of the foldable firearm.

Provided is a hinged firearm receiver configured to operate with an AR-pattern Bolt carrier group, buffer, buffer spring, and buffer tube. The firearm upper receiver has an integral hinge that connects to a rear receiver body and provides an AR-pattern firearm the ability to have a folding stock to reduce length for storage or transportation purposes.
