Hi, I am looking for a good AEG M4 for someone. We play in outdoor field and woods environments, usually with only small groups of people. He wants it to be full metal, but I keep saying he won't find a full metal m4 for under $150. He doesn't believe me, but I tell him that a good quality polymer body with some metal parts (Gear box, buffer tube, etc.) will serve him well in the long run, and not be so heavy. Does anybody have any thoughts on the G&G Combat Machine Raiders? I know the FPS is about 330, so will this be good for mid range outdoor gameplay? What about the hop-up, and subsequently the range? I would appreciate feedback from people with this gun. Also please let me know if somebody has a suggestion on their M4 choice. Thanks!
