Should work really well.

So far, so good.

It turns out that the exit pupil is simply the diameter of your optic’s objective lens divided by the magnification. For example, if you had 7×35 binoculars, that means 7 times magnification and 35mm objective lens which would produce an exit pupil of 35mm divided by 7 == 5mm which is smaller than the “perfect” exit pupil of 7mm. Since the exit pupil is less than 7mm, you may notice that you have to keep your eye perfectly centered on the eyepiece and even then you may tend to see a dark “ring” around the edges of your view.

Why did I go to the trouble to mention all that? If that simple Physics applies to the rifle scope featured in this article (and I cannot imagine why it would not), that means your highest usable magnification where you maintain an exit pupil of at least 7mm is: 28mm (objective lens diameter) / 7mm (target exit pupil) == 4 times. Similarly, that would also mean that your exit pupil at 10 times magnification would be a tiny 2.8mm (2.8mm == 28mm objective lens diameter / 10).

With that potential drawback–which is a potential drawback of ALL Low Power Variable Optic scopes with small objective lenses–I recommend that you look through one before buying one just to be sure that you like the view at the highest magnifications.
