Stoney point shooting sticks, I like them because it is not attached to the rifle so less to hang up on, the elevation is infinetly ajustable up to I am guesin 40-48 inches. They fold up similar to tent poles but way shorter I am gonna guess 8 inches, when not in use. I use them as a walking stick when I am on really uneven terain.
Just my two cents take it for what its worth
