Accuracy Solutions The Queens Combo Kit Black. Depending on the installation method (rail on top or inside the Queen's riser) the Queen's Equalizer Kit for BipodeXt allows the rifle to sit anywhere from 2.057 inches (52.2 mm) to 2.935 inches (74.6mm) lower than it would sit when the rifle is mounted to a BipodeXt. It attaches to the BipodeXt Front Plug on the one end and it receives a Picatinny rail on the other end. The rail can be mounted either inside or on top of the Queen's bracket. When it is mounted on top it lowers the rifle by an additional 7/8" (22 mm).
