Before you bother me about it, yes I did do a ton of searching on this website and Google and Youtube before making this thread. But there's still mixed opinions, and that's why I like asking the question to actively responding people. So I am thinking about buying the KWA M93R II, with the NS2 gas system (not the old one.) Everything I read on this website said it is KWA's worst gas blowback gun ever, but everything on Youtube or on the airsoft store websites (ASGI, Evike) say it's one of KWA's best. And then on the KWA website, one of the KWA workers (I'm assuming) said this: "All of the KWA GBB pistols run off the NS2 engine and while there are variations in the parts the performance is essentially the same. Regarding build quality, same as above, variations but no real quality difference." Does this mean all KWAs are as crappy as the M93R is according to you guys? Possibly. If the M93R is crappy, then which KWA guns are not crappy? Also, I barely want to do this green gas thing since I prefer CO2 because I don't want to refill the magazine every 10 freakin shots. But since I've heard the NS2 is "fantastic" (in comparison with other green gas pistols) on gas efficiency, I decided to look into KWA. But I've also heard that the USP, for example, lasts about 1 and a half mags on a fill of gas, whereas the M93R II lasts 2 mags. Why is there a difference? P.S. I know I made another thread kind of about this, but that was more about KWA's gas system.
