You don't need a press or a bowshop to perform maintenance on Excalibur crossbows. To decock an Excalibur crossbow install the cocking rope, remove safety, push on anti-dry fire device and pull the trigger...…………..pull on the trigger while holding the cocking rope with one hand. Any crossbow that can be cocked with a cocking rope can be uncocked with a cocking rope.
