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. The present invention is advantageous in that when fixed to the butt of the stock of a rifle the leg provides a means of supporting at least part of the weight of the rifle, in particular the weight of the butt and the stock of the rifle, on a surface. The invention is particularly suitable for use with a rifle to which a bipod is mounted towards the front of the stock of the rifle. The invention enables a user to provide stable and controlled changes to the elevation of the rifle on a target and to maintain the elevation of the rifle for an extended period of time while reducing the burden on the user to support the weight of the rifle.
