As of now the crossbow is not worth picking up really. It takes up far too much room with several bolts. In the beginning, cause thats when you will find and use the crossbow, you have very limited space in your inventory and picking up bolts that takes one slot each aint worth it. I would say that stacks of 3 or even 2 bolts per stack would make it a more attractive weapon. Either stacks of bolts or a proper ironsight, or perhaps both. Make it a hard choice to pickup the enfield instead of the crossbow.
