Hey guys, I'm looking for an M4 AEG that is at least under $350. It will be mostly be used for an indoor CQB arena? So a short RIS system would be nice. FPS doesn't matter because I can always throw in a m100 spring. Metal body would nice, and I don't know much about gearboxes so I can't tell you what I want. What company should I look into? KWA? JG? G&P? No G&G. Matrix? ICS?
