XtraArm Solo Shooting Stick w/ Double Yoke Black. Built to last a lifetime its made from 100percent rust-proof 6061 aluminum that can handle anything you throw at it-even frozen ground. It comes with multiple interchangeable extensions allowing you to quickly dial in your perfect height for any setup. The Double Yoke attachment is our go-to for bolt-action rifles offering excellent balance and stability. We originally designed it because our tripod was too bulky for ground blinds-we wanted something smaller without sacrificing stability.
