I tried the Mvan cs 1a ,it was compact enough,a little heavier but 65 mm lense too. Rotating mount too.
Eye relief with glasses was ok until I zoomed to about 35x.
Cabelas locally finally got the Razor angle eye piece version of the 13x39 x56 .
Compared both and kept the Razor,better eye relief ,lower weight plus neoprene armour, but giving up larger lens ,rotating mount less max power, and about 250 less dollars.
