Alas, I do not own any nice (as in expensive) scopes, all mine were bought as a cheap scope when needed to scope a rifle. That said, I put an old Tacso scope on my AR-15 and so far it has performed well after several 20 round boxes. I'm not a fan of AR's, prefer the old style rifles, especially military which are open sights.
I do have a Simmons scope that I mounted after the warranty ran out that was trash new out of the box. Good only for a shadow box now.
Since I no longer hunt, it just doesn't matter to me. Poor folk have poor ways.
