This is the Goblin, a single shot break open Silly Shell fed foam blaster. It can fire any ammunition type that can fit in a Silly Shell; you'll get solid performance from multi-dart shells, up to over 200 fps out of a sniper shell. You can also replace the barrel with a three-shot inline clip option (160 FPS), or even a singled option (200 FPS+)!
It also doesn't need much filament or hardware, which is cool.
