I have had (and still do) four different Leupold scopes, mounted on everything from a heavy load shooting 45-70 to .270 winchester, , .308 and inline muzzleloader. My oldest scope is thirty years old, and still (VX 3 1.5 x 5, of which I have owned 3...my favorite scope) as good as when new. I also have a VX 2 2x7 and VX 2 3x9. they all hold perfect zero,, take my accidental bumps (several which had been much more than bumps) without getting knocked out, and are clear as a bell. You pay for what you get more now than ever, and having also owned and used Tascos and Simmons, Bushnells, Weavers and Nikons, the only other brand worth considering was Nikon, but they are stopping production last I knew.
A used Leupold can be considered as good as a new. The company will take any scope back for inspection and refurbishing back to orignal specs without cost and return it to you promptly.
