    I made this crossbow and extended the tracks by about 4 more yellow pieces ...
    I promised my self i would never make it again becuase i put a peace of metal close hanger in it and i shot it through my wall and into the other one across the hall.

    Sadly I can't make this cross bow due to lack of certain pieces :(
