I was looking in a catalogue that I have and found something like what your asking about. It' s called a Stoney Point Expedition Sportman Staff. It can be used for a rifle rest or as a hiking staff. It extends from 36" to 65" tall and made of high quality aluminum alloy. The manufacture name is Stoney Point product, Inc. and they have a variety of different products. Check this wed site
