Check the listing for details. HOLOSUN HS407K-X2 Red Dot Sight - Black. Color: Black, Condition: Used. Listed at 138.00 USD. Up for sale is a used Holosun HS407K red dot sight. This sight had been on an EDC gun for a year carried daily. It had a decent amount of wear around all the edges but no significant damage. At one point I had used a sharpie to black out the holosun logos but it had mostly faded. The buttons are somewhat difficult to press, though, they came like that. I only mention this because all other holosuns I have don’t seem to be as difficult to push though this is the only 407k with the “x2” buttons that I have. It comes with the box and manual but does NOT come with any screws, mounting hardware, or other accessories.Up for sale is a used Holosun HS407K red dot sight.
