I put this on my .50 Beowulf and have only fired about 50 rounds through it so far and the scope hasn't rattled apart. This gun has killed a couple optics worth twice as much and this seems to be a keeper.
Pros: generous eye relief, bright, clear optic, positive adjustments
Cons: haven't found any yet
