The Wide Body Shooting Rest comes with a SwitcherooA(R) quick-change stem and is intended to be an alternate or replacement shooting rest for any BOG(TM) shooting stick. It is designed for those who prefer a low-profile shooting rest that's extra wide for additional stability. The Wide Body will provide the very same 360-degree head rotation that your original shooting sticks offered and will fit very snuggly into the center hole of the shooting stick's head.
