A little shout out to Leupold Optic's quality and customer service. My dad has a 47 year old VX-2 scope. Long story, it was dropped a number of years ago and would not hold a pattern. In the span of 3 weeks, he mailed it back (to Oregon), they replaced both adjustments, inspected it, and shipped it back. Free and no questions asked!
I've sent two scopes back to them. One was a 8.5-25x with a sunshade that I had the rifle leaning on a tree and knocked it over. The threading on the sunshade locked up and I couldn't get it off with a level of force that I was comfortable with. I sent it back and they took care of it as well as doing inspections and cleaning of the scope.
I just sent a 2-7x shotgun scope back that I thought maybe wasn't holding groups. They checked it all out, cleaned it, etc.
Both times - no charge and very timely service. They also sent me emails to keep up on the status of where things were.
Leupold is the best for customer service. Just found out (after 10 years) that I can get one scope a year at 50% off MSRP. Just received my Shotgun/Muzzleloader scope in the mail....It is my 5th one. Will never buy anything else.
