The Goblin leans heavily on the 'Rule of Cool', not very practical or convenient to use, it is nonetheless attention getting. The Goblin Solo (and the Deuce double barrel variant) utilize pre-charged 'shells' that each hold a single round. Each shell is charged with CO2 and is a self contained valve. The Goblin itself is just a device to hold the shell and a trigger mechanism. The barrel barely adds any effective length to the shell alone, but breaking it open and popping out the discharged shell to load a fresh one gives it a wild-west feel.
