I have an aftermarket TriggerTech trigger in my Excalibur Crossbow. About the same price point as this trigger. It's a 2 stage 2.5lb trigger and is worlds better than the factory trigger. Obviously the trigger for a crossbow is very different than for a rifle but if the break, pull and build quality are similar I'd have no problem giving it a try.
