The Handgun Tree Spinner target makes it quick and easy to set up your own shooting gallery. With threads on one end and a handle on the other, you can simply thread it into most woods then start shooting at the stacked spinning targets that measure 3" and 4.5". When hit, they can be heard and spin around then can be removed with ease when you are finished. The Handgun Tree Spinner is made with solid metal construction to withstand 9mm to 30.06 Soft Nose Lead. No assembly required.
