I've had 2 pair crack. They were on rifles that spent a lot of time on ATV's and tractors (as well as hunted and shot a lot). Have other LW's still mounted that haven't cracked but I've moved to DNZ's and haven't had a problem with them yet.

I like this option as well. I have a couple rifles set up with seekins rings and really like them...but those two haven't been run through the ringer as much as those with DNZ's.
