NIB, never mounted. Was removed from the box, checked function of the dot itself, and realized it wasn't going to come close to fitting on my slide even with an adapter. Still in all original packaging including the mounting screws and MOS adapter plate. Open to trades, just make me a reasonable offer. Can add cash on my end for the right deal.
