Dude I say make 2 prototypes! One with the 12 gram CO2 system you've developed and then another one using the Goblin Solo air cartridge system! Heck make a third one that could use both systems and you've got yourself a nice versatile pistol! And I'd say sell this puppy off to Tiberius Arms! I could only imagine using First Strike rounds in this beauty! Quick Draw duels anyone?
