I must be fairly lucky with Leupolds after reading some of these posts.....I have dozens of them (along with many other brands) and have yet to have an "issue". I have them on hunting rifles, slug guns and pistols, target rifles and pistols, and just casual "plinkers". The target rifles include several silhouette guns and long range rifles that require constant elevation tuning. Certainly not saying things can't happen with any product and I'm sure that I do not shoot as many rounds as some here but I am happy with my experiences with Leupolds both old and new.
