    Abstract: Our integral user configurable sniper rifle stock comprises a wide forearm and a relatively narrow carry portion extending rearwardly from the forearm. An action mounting portion extends rearwardly from the carry portion. An angled relatively vertical, stippled grip extends rearwardly and downwardly from the receiver portion. An open rear stock portion extends rearwardly from the grip. The carry portion is narrower and thinner than the forearm. The action mounting, grip and rear portions are generally as wide as the carry portion. The forearm comprises a forend having an angled base and a flat serrated base portion extending rearwardly from the forend. A "T" channel rail is disposed within the angled base to mount a bipod. The folded legs of a bipod lie along the barrel. The grip defines a weight receptive cavity. A trigger guard extends from the receiver portion to the grip. The rear stock portion comprises upper and lower braces with a butt extending vertically between rear extents of the braces.
