I have sent scopes back to Leupold that needed to be refurbished, or the parallax re-set (a friend asked for it). I have had some Leupolds that I feel never should have had a problem, based on what they were assigned and how I handled them. But, Leupold stood behind the scopes and re-built them, AND got them back to me promptly. When it comes to optics, buy the best you possibly can, it pays dividends in the long run.
If I have a problem with a scope, I want to get the same scope back as I sent. If a company sends me a new scope, I ask myself: Did they stop making the old one? Did they up-grade me to make me feel better, or themselves? If they send me a NEW scope, what was so wrong with the old one they couldn't fix it? Is it just so crappy they don't want to bother?? (Of course the scope has to still LOOK like a scope for me to ask that one.)
Its like going to a junky....auto recycler's emporium, and buying a used engine, or any part, for your car. They'll sell you that engine, and if you have trouble with it in 30-40 days, if the heat tab is still in place, not burned, they'll give you another NEW used engine, but what about your time? And, if your scope dies in a match, and you don't have another brand-new one, is that really doing you any good? Just because a company gives you a new product doesn't necessarily mean they make good things, it may just mean that they banged you so hard, in the first place, that they can afford to give you a freebie because their stuff is too overpriced to begin with. A good example of this was the old Redfield low-powered variables made in the US prior to '68. If you tried to register that scope in '70 or '72 they told a friend of mine to just send that scope in, because they wouldn't warrant it, but they'd send him one of their nice "new" scopes. This was about the time when they tried to make the TV-screen ocular the rage. I think some of the guys on here like to say, "Buy it good, you only cry once".
