So far, this 2nd iteration ZA5 is a major improvement in eye box. It is the 30mm tube, and I do prefer 1" for my hunting rifles....this one will ride on a dual use 308 AR, so it will be fine with a 30mm tube and 50mm obj for hog culling and tactical target work. The test will be whether I like the 1.5-6 with a 30mm tube for a hunting scope. Worst case, it could end up as part of a dual setup for that AR, or another AR. I think their discontinued 1.8-8 ZA5 model probably made the best 'package', but they need a better #4 reticle, too.
