I am selling a used not abused m4 by cyma. The internals have been swapped with a g&g combat machine cm16 gearbox and motor. This comes with two kwa k120s and a 7 inch noveske keymod rail and mock suppressor. Also has red externals with a mix of ares and other brands. PP only, buyer pays shipping, comes with two batteries and a charger shoots 340-360 fps
