Red dot sights - help me out
Ok, I never really liked having a scope on my gun. Aside from being a little long, I practically never have the need for 3x magnification, which is the lowest power setting I've got on mine. Red dot scopes are much shorter and less obtrusive, and since they're all 1x (at least all that I've seen, 1.5 or 2x might be nice) it seems like they'd be easier to practically use. The only difference I see in some of them is that they're listed as 30mm or 35mm or 45mm. What exactly does that mean? Does it make any difference?
