>>6451276If you wanted one at a lower performance lever for safety reasons (especially for indoor wars) the way to address that is to print the RAM component with a more restrictive inner diameter. I will try to experiment with that in the next month since it has been asked before.
The design as-is is really intended for NIC wars which are largely outdoors and involve engaging targets from beyond 60 feet. So muzzle velocities of around 200 fps (or more) are typical.
The Caliburn design can manage to hit those speeds even with cheap full-length darts. There also the bonus of being able to load up to four darts into the barrel should you want to.
