Ok here I am again wondering about optics just the other day I thought i knew what I wanted but i did a lot of research and found out some things I didn't like about my other options. I've had NF products before and always liked them but I've only owned the NXS 3-15 so my question is, is the 3-15 F1 worth the price difference from a 5.5-22? I mean I've heard the glass is alot better in the F1 but you can find 5.5-22 for around 400 bucks cheaper? Is the glass 400 bucks better to have 7 less power? I can only get around 700 yards to shoot so the 15 power would be enough (but can you actually ever have enough power)? Thanks for the help again.
