I have several Kaps scopes, and like them very much. Comparable to the best European scopes to my eyes. One is a fixed 4x on my .375 H&H. It is a very good match to that rifle, and has been completely reliable. I also have a 1-4x ( first focal plane ) on another .375, and a 2.5-10x ( also ffp) on a .308. No worries.
