I would love to have the upgraded missiles for MP-18 Bluestreak! There are several versions of this (I think one is G7 and the other is Dr Wu) and if you have a set for Bluestreak that you don't need I'll gladly take them off your hands! Thanks
I just saw these today and it might help. Sirtoys sells a KO one. It looks like a loose version of the ones that come with the KO versions and I have no idea what the quality is like. Shipping is kinda high for just these, but it's an option. Shoulder Cannon MP18 - MP - SirToys.com
