I have a few scopes, actually more than a few, no longer shoot with open sights to my satisfaction, so. I prefer the Mil dots with a second for short range targets being the old duplex, I have several others but most of the bells and whistles I never actually use. Actually learned the mil dots in the military with a M-14 I built for my use.

Probably my absolute favorite is the mil dot, with a lit dot center that disappears into cross hairs when you turn it off, works well for low light.

“To expect defeat is nine-tenths of defeat itself. It becomes a self-fulfilling prophecy. It is best to plan for all eventualities then believe in success, and only cross the failure bridge if you come to it."
