Below are all the Holosun Rifle optics that have a large window. These red and green dot sights are offered at the best price with free shipping.

All of these optics have larger windows with large field of views. These have 2x the glass surface area than traditional 20mm tube red dot sights. These are comparable to an EOTech optic.

The large windows are really pleasing to look through and allow for faster target acquisition and more targets in view at once.
