Eye box not as forgiving as other VX3s; mine is a VXIII, don't think this has changed. No issues with critical eye relief (at least I've not noticed it).

Mine is on a .264, a dedicated antelope rifle, with B&C. I like it alot. Some here will tell you that a 3.5x10 is better, because of more latitude in the eye box. I've had both, and for my purposes, the 4.5x14 is better.
