K'nex Double-Shot Crossbow

Here is something i made yesterday, it is a double-shot crossbow, it shoots 2 bullets at the same time, both bullets can go up to 15-20 feet depending on your rubberband, it is my first crossbow, so go easy on me, i will be working on a V2 (version 2) very soon. i take apart creations after 3 days, no one asking for instructions, i will take it apart.(This will be the last time i say it)
