After looking at a lot of scopes, accidently came across the mueller site. Got the 4x16x50 red dot. Have nothing but good things to say about this scope. Have friends with high dollar scopes that just cant believe that this scope was as clear as a scope costing 500 and up. The red dot I have used in daylight and at dusk, wont ever go without it again, and has friends looking for the website. Has anyone else had this same reaction to this scope? And does anyone know of a long term test review?
