There are several different brands & styles of red dot optics. But I've found the UltraDot's to be an excellent optic. You won't go wrong with one of them.
Thanks for the responses! Now I will see if anybody puts them on sale!
I have always wanted to try one but wondered if they were better than the other red dots
+1 on the UltraDot. Can't go wrong. I've got one from the '80s, and one from the '90s.
When all the "cool kids" with the reflex-style sights are busting your chops about your "old-fashioned" red dot, show 'em this link: http://bullseyepistol.com/dotsight.htm
It includes this quote, which I have always loved, for some reason:
"On a positive note, in this game of bullseye shooting, I have seen more military shooters over the past 15 years at all of the big matches using the basic UltraDot model than any other sight - and without question, these guys are truly the pros of the sport."
