Ok for this pic you can see it has no trigger, that's because in not good at makeing trigers, well for crossbows anyway...
I don't know the range of it for i use weak rbs do to all my good 1s r ether :under something, destroyed by my cat, or put somewhere without me knowing... Ok anyway i used 2 hairbands on the limbs and they work really good, for me it fires 30ft before it hits something (this is with my ammo that i made, last step shows the ammo and how to make it)
Step 1: The stock pt 1
7 blue rods
9 yellow conecters
1 grey connecter
(note that the blue behind the yellow is in middle connection thing not the hole except the 1 near my hand thats in the diagonal 1)
