prism
In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, plastic and fluorite.
A dispersive prism can be used to break light up into its constituent spectral colors (the colors of the rainbow). Furthermore, prisms can be used to reflect light, or to split light into components with different polarizations.

Very gently used PA SLx Gen II 3x Prism Sight.
I had this on a 5.45x39 Vepr that sits in the safe most of the time. Maybe 200 rounds through it with this sight installed.
This thing is very clear with good eye relief, I just replaced it with the newer/smaller Gen 3 prism.

I have a Sig Bravo4 prism sight. These were made to compete with the Acogs and are no longer made. Pretty hard to get your hands on now and even harder for the 300blk model. It's been on my 300blk build for about 100rnds but I decided I'd rather go with a different style optic.
