If you're looking for a fast sight, you'll be hard-pressed to find one quicker than the Bushnell® HOLOsight.® Lauded by experts as one of the most innovative gunsights ever made, the advanced holographic technology found within our HOLOsight lets you bead up on a target as quickly as you can raise your gun. It's that fast. HOLOsight projects the appearance of an illuminated crosshair 50 yards in front of your gun, yet no forward light is projected. Sight from any distance behind the gun without taking both eyes off of the target. Offers unlimited eye relief and an unlimited field-of-view. At half the size of a conventional sight, it fits easily on handguns, shotguns and rifles with a standard Weaver-style mount.
