I don't have a clue about scopes or red dots. Looking for something sub $250. Don't know if I need any magnification, but would like to use the Charger throughout it's effective range. I looked at a red/green dot Vortex today at my LGS that came with an attachment for magnification but significantly decreased the viewing window. Without the attachment I liked it just fine, especially the spring loaded lens covers. They are asking $170 for it.
What have you used in this type of application, what worked, and what should I avoid?
