Abstract: A rack for transporting on an all-terrain vehicle (ATV) a long gun such as a rifle, shotgun, or a hunting bow has a clamping arrangement which engages the limbs of the hunting bow in a direction substantially normal to the limbs at the point of engagement and clamping. The rack further has support arms for holding and supporting a hunting seat such as a tree stand or deer stand for transportation. Additionally, the rack is provided with two detachable cradles which may be disposed on a portion of the clamping mechanism and clamped by the remainder of the clamping mechanism. The cradles have hook-shaped support surfaces disposed for supporting and holding a long gun in a substantially horizontal orientation.
