The vise has a mounting clamp that will spread to 2 3/8� so it can mount to most benches, tables, or an LCA bow press. Included standard with the Revolution Vise would be the Multi-Axis Head and two insert sets. Additionally, you can purchase the Stabilizer Head or the AR15 Head as add-ons. The Multi-Axis Head can hold almost anything. It includes smaller flat surface inserts and larger inserts with rubber pads to give the head maximum versatility. Setting the 1st, 2nd, and 3rd axis on your bow is a breeze with this vise setup. Purchased separately, the Stabilizer Head uses a threaded insert that mounts into any bows stabilizer mounting hole. This head and the Multi-Axis head can tilt up/down, including levels for precise adjustments. The threaded insert has a quick release, so it can easily be installed or removed from a bow.
