I hope that they are still producing their kits from time to time. The M16A1 and XM177E2 kits are not always in production, so it is possible that they are not available for a few months. Anyway I think that Marushin stopped producing the M655 Carbine kit long ago. Remember the first kits (like the UZI) came unpainted with a spray can.
But if they used thir old molds for their Airsoft project this may be bad.
Anyway I guess the MP40 kit is still the most popular and quite cheap modelgun, and it is sold worldwide.
Originally I wanted to get me the "mil coat finish" assembled XM177E2, but I had to ditch this. Anyway I did not really like the green finish. A dull grey would have been much better.
