Looking to sell my King Arms M4. Need to clear out the closet before I move. Comes with the attachments pictured and the rifle itself (obviously). The stock has a tendency to loosen itself over time but that's what the armourer's tool is for. Rifle was in good working order last time I used it, however I haven't had a chance to fire it for awhile (no charger and was living elsewhere). It has US Gov’t M4A1 trademarks. The battery is a 9.6v nunchuck that fits in the crane stock. The faux-Magpul stock will only fit LiPos.
