  • Patent number: 8826580
    Abstract: The present invention relates to a telescoping leg for a firearm such as a rifle. The leg includes a pair of telescopically slidable elongated members. The first member is configured to be fixed to the stock of a rifle. The second member is telescopically slidable relative to the first member between a retracted position and an extended position. The leg also includes a biasing means to bias the second member towards the extended position and a damper means for damping the movement of the second member between the retracted and extended positions. In one form, one of the first member and the second member is a casing having an inner surface defining in part a gas chamber, the other one of the first member and the second member is a piston received at least partially in the casing for reciprocation along an axis between the retracted and extended positions. The biasing means includes a compressible gas contained in the chamber that yieldably biases the piston towards the extended position.
