I have a nice ICS M4 with iron sights. It comes with a large batt, box, and a couple of mags. It comes with with 2 uppers, one thats stock and the other shoots around 400fps with .20's. Both the uppers and the lower have been gone through by Jared over at Gearbox. It is a REALLY nice rifle, I really enjoy it. Unlike a CA style gearbox, if you screw up a piston all it takes is 15sec. to swap out the upper.
Heres a pic of the gun, not mine but just for reference:
$220I am also willing to trade.
