Alright guys, story time. Long long ago, in time immemorial, I was just getting into the sport of airsoft and wanted the very best gun on the market. Having never heard of systema ptw (Not that I could have afforded any of their kit), and being the naive noob, I sunk $500+ on a custom built DMR with mostly TM and G&P components, purchased from a shady custom builder. While I was most definitely overcharged, my unique baby never let me down, with zero maintenance and zero after-purchase upgrades ever required. (I silicon oiled it ...maybe once?) This experience severely spoiled me, and now I can't even do basic maintenance without my evil fingers screwing something up permanently. A few years back, this AEG was stolen from a locker in between games, and I never replaced it, choosing to rent whenever I played, as I couldn't justify spending so much money again on a hobby I engage in maybe 5-6 times a year. Now, I've saved up approximately $200 to invest in a quality AEG. What I am looking for is this: FULL METAL EVERYTHING. I am in with the Mil-sim crowd, so full metal is a definite +. At the very least, I'd like the body to be full metal. LONGEVITY. I need something that will last and last, not unlike a TM which will see almost no drop in performance even after a decade, with next to no maintenance. (As I am mechanically inept in almost every way.) Though I know I can simply purchase the parts and upgrade later, I'd prefer RIS rails or similar tacticool garbage, as I tend to go crazy with lights and optics. This is going to be my main for the foreseeable future, so I need something for field play. There are no FPS limits in CQB situations where I play, so even 400+ FPS out of the box is fine. While everyone is sick to death of the m4, it's never going to go away and the aftermarket upgrades for it are plentiful, so anything in the m4/m16/closely related family is fine. I've compiled a list of potentials; remember, what I am looking for is something that will last me for at least the next 4-5 years without needing replacement. Feel free to contribute others to the list, with reasons why they are superior.

This runs the gamut from King Arms to ICS and even the highly rated JG M4 S-system. However, I am not sure which have the best price/performance ratio while also providing the longest possible performance on top of that. So... anyone have an opinion?
