The EZ Aim Shooting Gallery Target Shooting System is a build-your-own shooting gallery kit. The package includes target stand legs, gong hanging kit, two spinning targets and frame, two brackets and paper target stand. Brackets will accommodate all Allen Company spinner targets if you want a more expansive shooting target gallery. Supply your own wooden 2x4 and steel gong target to complete your shooting system kit. Use the EZ Aim Shooting Gallery Target Shooting System with a 2x4 (not supplied) that is a minimum length of 18-inches. If you want the targets spaced further apart then use any length of 2x4 greater than 18-inches and install the supplied targets at your desired width.
