There is much more demand for variable scopes. with a witty variable you can use it on 4 power if you wish but I always use more power than 4
As much as I do like a simple 4x scope, you are right. A new VX2 in 2-7 is a nice trim scope, just as lightweight as a 4x and offers more flexibility, esp at the range.
I have one of those on a rifle...and I am constantly surprised...but seems like every time I have taken game with it, I look at the scope afterwards and notice I had it turned down to 2 power once again...
so "lack of magnification" didn't seem to handicap me much at all...and its not like I am Mr Eagle Eye...
I find a 2 x 7 is more useful for my needs than a 3 x 9.
