I wonder if you could cellophane-wrap all the functional internal parts and a "seam" between the two clamshells, button it up, fill the thing with Good Stuff expanding foam, and then crack it back open when it has dried and carve open any channels that got plugged where moving parts need to pass through...

You'd end up with a quieter, stiffer, heftier-feeling blaster... but it seems like it'd require a lot of fiddly work with a utility knife.
