P.S.
Almost forgot.
If the reason you're thinking of going with a red dot is being unable to see your sights, you might consider getting prescription shooting glasses.
That's what I did.
Right eye allows focus on the sights and left one focuses on the target.
Works real well.
I do use red and green dot sights, too.
But for the action games, like steel challenge and such.
They are quicker, but less useful for the pin point accuracy that Bullseye requires.
