Looking to buy a UltraDot, open sights, not the tubes. Either the LT or the Pan AV for a S&W 500. I want to spend $200 dollars, at the most for one. The red dots are new to me. Like to use it for target shooting, possibly hunting. Would like to have some feedback on the UltraDot as well as others with open sights, in the $200 price range. Thanking members in advance for replying.
