That is really strange. I have 1x6 trijicon creedos on my 416 rigby, 416 rm and my way too light 458wm browning and have hammered them with no issues. The old steel tube leupolds I think were durable glass but the new stuff..not so much. This is really the first Ive ever heard of issues with trijicon and nightforce. My personal experience has trijicon and nighforce besting swarovski and leupold in durability but I have not personally owned many other brands so cant speak to it. I am pretty sure I could smash a VX5 to bits with a bottom of the line trijicon huron and it would still hold zero.
