Burris fastfire iii - Burris FastFire III Reflex Red Dot Sight

I Previously purchased a lower costs red dot, which works well on my shotgun, but I wanted one to use for Steel Challenge with a pistol and I am SUPER PLEASED at how quickly I can acquire and hit a target. I definitely recommend this for ease of use and ESPECIALLY since the battery can be replace WITHOUT having to remove and having to resight it back in.
