Price is shipped, buyer pays fees. Base gun is a KWA KM4A1 with stock gearbox, upgrades include a king arms high torque motor for great trigger response, new bucking, extended inner barrel, Matrix battle motor grip, suppressor, and Car 15 stock, and wired to deans. Here is the small list of tiny issues, one of the body pins had to have the screw drilled out of it, but fits snug, and the middle hopup wheel peg broke so I had to drill and super glue one in, should hold up fine. Other than that it runs great and kits hard.
