I built a remote airsoft stationary turret using a crosman elite battlemaster. I spent about a whole day on it finding the right parts. Basically the gearbox is connected to the "receiver" with wires I connected. The "Transmitter"(controller) transmits to the receiver. So instead of "turn left" it's "take out this chump" lol I'm not sure how much this is worth due to the fact that I built it myself. But I can say it's a freaking remote turret if that helps my cause. I'd be glad to negotiate any offers. And since it's such a big gun I'd rather meet someplace than ship it. Tri pod is NOT included
