Abstract: A bowstring release system for crossbows having a preferably ball-shaped nocking member mounted on a bowstring for engaging a nock portion of an arrow. Upper and lower surfaces of the bowstring release system are positioned near the rear of the crossbow, and move between open and closed positions relative to each other to vary the size of a release passage defined therebetween. In the closed position, the upper and lower catch surfaces are positioned sufficiently near each other to block the nocking member from passing through the release passage. And in the open position, the upper and lower catch surfaces are sufficiently separated to allow passage of the nocking member for propelling the arrow. When the bowstring is cocked, a locking mechanism actuates one or both of the upper and lower catch surfaces to the closed position, and a trigger mechanism releases the locking mechanism and actuates either one or both of the upper and lower catch surfaces to the open position.
