You my friend have a problem.I have 10 nx8's, 3 atacr's, 2 TT's, 3 zco's and various leup's. I prefer the 4x32 over 2x20's. The 2x20's needed another 1/2"of tube. The shorter tube in front does not allow for a lot of adjustment because it is so short. If your eye is where it's suppose to be then the eye box is fine. Get either way of it .2" of an inch and yes the eye box is quirky. But honestly I can say I've never had an issue with them.
