Abstract: A device for the support, transport and use of a rifle on a motorized vehicle. The device includes a vehicle attachment plate for fixedly attaching the device to a surface of the motorized vehicle, such as an all terrain vehicle. A box frame is connected to the attachment plate which includes a pair of parallel extending swing arms pivotal at their proximal and distal ends to a lower support bracket and rocker bar respectively. A rifle support bracket is provided which is movable from a first rifle storage position proximate the vehicle attachment plate to a second rifle deployable position at a height elevated from the first position while maintaining a constant orientation of the rifle support bracket with respect to the vehicle attachment plate. In addition, the rifle support bracket is selectively rotatable with respect to the rocker bar.
