I recently bought a Leupold VX-3 used . It was in like new condition , but the Power Ring turned really HARD . Not the Sellers fault as he is a good guy and made it right . So I sent it off to Leupold about 3 or 4 weeks ago . Just got it today , and it is slick ( no charge ) . I own a lot of different Brands , but mostly Leupolds . The 2 or 3 I sent back years ago were also purchased used , and were also promptly repaired free of charge . Just wanted to report my recent experience with Leupold Customer Service .
