I have an old Diavari Z that I bought (20) years ago. It has spent most of it's life on two magnum rifles, first a .300 H&H and now a .300 WSM that my son now uses for elk hunting. It has survived (20) years of magnum recoil and is still bright and going strong.
The MC coating is used on old US assembled scopes. The T* coating is used on all German made Zeiss scopes.
