ABSTRACT:
An ergonomic adjustable gun stock having an elongate forearm portion with a longitudinal concave receiver channel in its upper surface for receiving the barrel of a gun, a butt portion extending rearwardly from the forearm portion, a vertically adjustable cheek piece, a longitudinally adjustable and removable auxilary hand gripping element on the underside of the butt portion, and an adjustable recoil butt pad assembly mounted on the rear end of the butt portion. The forearm and butt portions are generally rectangular polygonal configurations having a subtantially flat bottom surface and substantially flat opposed sides. The butt portion has a rounded top surface substantially parallel with its flat bottom surface. A thumb receiving aperture extends transversely through the butt portion near its forward end and defines a contiguous generally vertical handgrip portion adjoined to the forearm portion and a horizontal lower portion which also has a substantially flat bottom surface. The cheek piece is an inverted generally U-shaped member having a rounded top surface and contiguous laterally spaced parallel sides. The butt portion has a cheek piece receiving recess sized and shaped to slidably receive the cheek piece in a lowermost position, such that the outer periphery of the cheek piece is generally flush with the outer periphery of the butt portion in its lowermost position.
