I have one on the way, how bad is the eyebox?
Definitely usable. It's not horrible by any means, so don't get alarmed. The exit pupil should give you a rough idea.
I was probably expecting an unrealistic improvement of the 12x version over the 18x version. However, I am shooting some contorted positions and the LRTS scopes just don't seem to agree with me. More annoyance than lack of functionality. I've been communicating with some other shooters who feel the same way. Both .mil and comp shooters (asking them for opinions on the DMR II). But, do your own evaluation, as this may not be relevant to you. And, this really boils down to nitpicking and personal preference.
