The reason why it's so inexpensive is because it currently does not work (PLEASE KEEP READING) I went to the airsoft shop and they said it would take about $40 to fix or you could just use it for parts LITERALLY has never seen a field and has only been used for test firing which I've only done maybe 4-5 times so it's basically brand new. The problem if you're wondering is it's getting no power to the gun to fire so it's somewhere from the battery to the wire connecting the battery to the gun. It comes with everything seen in the pic Also the reason why I'm selling and not fixing KS because I want a dmr type gun
