Turbo Advance(AF Superdrum) Shotgun Mod

thingiverse

This is a dual air port for the Zuru X-Shot Turbo Advance(Adventure Force Superdrum) that allows the inner and outer barrels on the drum to fire at the same time. I recommend also upgrading the plunger spring, and catch spring, as well as reinforcing the priming bar with epoxy putty. You will also need to glue some foam to the front to make it seal to the drum. This is a reversible mod that simply replaces the stock air selector on the blaster.
