Abstract: A portable shooting bench assembly has a base chassis assembly with a wheel member that contacts a support surface upon elevating one end of the base chassis assembly. An L-shaped turret chassis member is pivotally mounted at a first end to the base chassis assembly and follows the contour thereof. The turret chassis member's second end is supported on a roller member that contacts the base chassis assembly with a seat member secured above the roller member. The first end of the turret chassis member contains a vertically telescoping section, having an offset support arm member and a linear, rifle support assembly adjustably secured thereto. A hunter seated on the seat member moves himself and his rifle positioned in the rifle support assembly by pivoting the second end of the turret chassis assembly on the roller member along the base chassis assembly.
