Abstract:
An adjustable buttstock assembly for a hand carried weapons, wherein an inner stock extends from and slidably moves into an outer stock to provide the length adjustment and where a set of opposed spring loaded engagement pins, located in the end of the inner stock, extend through a set of discrete, opposed openings in the outer stock to securely hold the stocks in position one relative to the other. One of the engagement pins, engages into one of a series of discrete holes located in the lower side of the outer stock, while the other engages into one of a series of partial oval opening, opposed thereto, the series of partial oval openings located on the upper side of the outer stock separated by flat teeth, to form a rack, with each partial oval opening into an open channel running the length of the rack. Such that when the lower engagement pin is compressed into the lower opening in which it may be and the upper engagement pin then rotated out of the partial oval opening into the channel—the inner and outer stocks are then free to move one with respect to the other to extend or compress the adjustable buttstock. Further, the inner stock is fixed to a backplate that engages with the receiver of the weapon, and provides protection for a hydraulic buffer that engages with the receiver of the weapon and extends into the inner stock.
