in my old age i find myself using hiking poles a lot so my rifle isn't in my hands like it used to be. which is ok until the one time its not. I've slung my rifle before on my back with low carrying packs, and I know about the hunters backpacks that can carry your rifle on the side, or a hook on an external frame pack. I don't like the time frame required to shoulder a rifle from those methods.
is there a trick way to carry a rifle hands free that also allows for quick access for use ?
