Gently used Holosun 510C red dot sight. This sight works fine - I bought it and then figured out that I have astigmatism serious enough that using a red dot isn't the best choice for me. Comes only with what you see - the box, manuals, and other accessories are long gone, though the manuals can be found online at Holosun's website.
