Old eyes made sharp again. - Ultradot 30mm Red Dot Weapon Sight

My eyes aren't what they used to be. I made this purchase for a 357 cal. GP100 revolver (my fun gun) After sighting it in at 25 yards, my targets look much more impressive. The dot brightness is adjustable and it holds its zero through heavy rounds on my Ruger. I've fired about 250 rounds so far and its performed wonderfully. The battery has not expired yet so I can't tell how long they last. It comes with everything you need. the mount rings are good, the sun shield, and filter are good. Optics Planet has been the lowest price on the internet I could find.
