Lego modular crossbow. It has perfect performance. I don't know what is the maximum range. The feature is in bow construction which gives bigger length of the rope to accelerate bolt. In xubor's one rubberband accelerate it. But i used inelastic rope. it means that thousends shots will have one power (it is really powerfull and accurate :) )
It can be loaded for a really long time without losses of power. Also bolt are stramped after reloading and don't fall out.
and i forgot. I made range test on distance 9 meters.
Sorry for foots XDD.
