I bought a credo HX for my 375HH, I looked at the Zeiss but wasn’t sold. If you look at drop tests here, I believe the Zeiss stuff generally fails while trijicon stuff is known to be pretty rugged. Maintaining zero was worth the extra weight to me on this one as the rifle is already a bit heavy and just not intended for backpacking. It’s going to get bumped around in boats and rafts.
