I don't know what ww2 airsofting guys you know, but
http://ww2aa.proboards.com/index.cgi is the biggest I have found and they do not suggest it for skirmishing at all because of poor performance. Accuracy and power is very poor along with having to use shells. I was thinking about buying it because it was a kar98 at about $100, but you are much better off getting a vsr10 clone as it preforms much better and can be upgraded. I said fuck it got a Tanaka Mauser which, as it turns out, was not a good buy either.
