I've narrowed down my decision on a new Airsoft gun to either the Echo 1 P90 (or E90) and the Well R4 (MP7). Both of these are Tokyo Marui clones, which i dont have a problem with. I play CQB only and the P90 seems ideal with 300-350 FPS and good comfort and mobility (plus an extra mag). But my limit is $175 and its $155 and I sorta wanted a red dot sight to go with it. The R4, being only $100, has only around 250 FPS. But it would be easy to get a sight and some spare mags and stuff like that for it. What do you think I should do. ( Please, no arguments about paintball vs airsoft)
