I have a trijicon on my Muzzle loader. Unless they make really good scopes and really bad scopes his story is exagerated.

One time I was climbing up a very steep part of the mountain on some rocks. Gun is slung over my shoulder as I'm climbing and I reach for what looks to be a steady rock but it moves causing a bigger rock to come down from above. I ducked and leaned far to my right so this rock wouldn't take my head off but the scope is bashed hard against the rocks from all my movement.

It has a gash in it from the rock. I killed a doe a few hours later.
