Abstract

A trigger assembly for a crossbow or other weapon system. The trigger assembly includes a trigger arm coupled between a trigger and a sear. The trigger arm is not parallel to the line of fire, thereby allowing for increased mechanical advantage and a smoother, safer trigger pull. The trigger assembly incorporates various safety measures, including a dry fire mechanism which prevents the unintentional damaging and potentially dangerous release of the bowstring before an arrow is positioned on the rail of the crossbow. The trigger assembly allows for various adjustments to vary the trigger length and pull, while maintaining smoothness and preventing the unintentional or inadvertent release of the bowstring.
