I've got an E1 M249 in need of repair/upgrades. This is what I've got spec wise on it: Standard A&K gears M120 spring(I think) Green Piston with one metal tooth SHS High Torque Motor short type Non-ported cylinder Plastic nozzle and cylinder head Standard A&K M249 trigger switch Deans plugs. My budget's around $150, may rise and fall depending on my situatons at hand. If it's fairly cheap to ship, I'd also like someone to work on it for me. My target fps is between 410 and 425, mid 20s rof, on either 7.4 or 11.1(Haven't purchased any batteries yet.) Any insight as to what I should buy, or plans for it are greatly appreciated.
