I've decided to get a Trijicon Accupower scope for my AR. I'm just not sure about what power range to go with. I'm wanting to have the capability of making fairly precise 500 yd shots if need be but also be able to work fairly close. My eyes are good at the moment so I can see 500 yd easily. Having hunted with a 3-9 on every deer rifle that I've ever owned, I know the advantages and limitations of the range. I have zero experience with a 1-4x scope and how precise you can be at longer distances. Can anyone help me out here with your experiences?
