Reflex sights are a far superior alternative to aiming a telescope then the more traditional finder scope. It is so easy to find your way across the sky, you would never go back to a finder scope. They of course just fine on any air soft, or pellet gun, and of course firearm. They are small and compact for easy storage. I have 3 multi reticle reflex sights. Two are without a laser @ $20 each. 1 with a laser @ $30.
