AC-Shop.net (based in Taiwan) have posted the new KWC C02 UZI on their pages today. For anyone that missed it this new GBB runs on freely available 12g CO2 powerlets, although given the nature of the power source the output power is above that of your standard desk toy.
From their post it looks like the new CO2 beast will be available tomorrow (19th) at a price of 5,200NTD (normal price 8,500NFD).
Specifications for the new CO2 GBB are given as a magazine capacity of 38+1, a weight of 2150g, a muzzle velocity of 150m/s (on 0.2g BBs) and a length of 350mm – it does have hopup mechanism installed, but there’s no mention as to whether it’s variable or not. Expect to see this new model hitting all your local shops shortly.
