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.

An adjustable cheek riser is described. The cheek riser may include a cheek plate and a mounting plate. The cheek plate may removably couple to the mounting plate and configured to slide laterally along a mounting plate length. The cheek riser may further include a horizontal adjustment mechanism, which may include a first fastening member and a second fastening member. The first fastening member may be disposed on the cheek plate and may include a male boss. The second fastening member may be disposed on the mounting plate and may include divots or notches. The first fastening member may engage with the second fastening member to lock a position of the cheek plate on the mounting plate.

A stock cheek riser that includes two side walls connected by a hood, which form a channel for receiving a stock. The stock cheek riser is sized and its front face angled to provide sufficient room for manipulating a charging handle of the firearm to which the stock is attached, when the stock is in a collapsed position.

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.
