a&k based mk46 with zci high torque motor, shs 13:1 gears, madbull tbb, shims, new piston, new wiring, etc. Shoots like a dream, and comes with peq lipo, elcan with Dr, stock a&k mag, MAG 2500rd box mag, grippod, and a full m249 stock as an extra. I will only trade this for a nice tm or vfc mp7 setup.
