their eye relief is .2" less than others in their class. I've never noticed the difference when comparing them to other comparable scopes. They are not my favorite scopes but I wouldn't hesitate to recommend them for their value, quality and durability.
YMMV.
Is that it? Maybe my concern/dislike of the eye relief is a function of them being 3-9, and not so much that itsa 4200. (as opposed to the 1-4 I have that has huge ER)
huh.
