Abstract: A device for mounting to the rear rack of an ATV for holding a gun or bow for transport includes a horizontal anchoring member attached the device to the rear rack of an ATV by U-bolts. A corner brace is welded to one end of the anchoring member. The corner brace is provided with a pair of threaded mounting pins which are used to hold a scabbard-type gun boot or a bow adapter for holding a bow. The scabbard or bow is held in place, when mounted on the pins, by threading and tightening a mounting knob on each pin. A bow adapter is made up of a main support member mounted on the mounting pins and secured by the mounting knobs. The support member is provided with a U-shaped bracket and a C-shaped bracket for frictionally holding a bow. A dual mount adapter may be used to mount an additional gun boot or bow adapter. This dual mount adapter includes a mounting plate engaging the mounting pins and secured along with a first scabbard or bow adapter by the mounting knobs.
