Check out Sightron scopes, amazing warranty and service. Covered a cracked objective after a drop, and I even mentioned in the letter what happened. Was hoping for a repair bill, and it was fixed for free.
Also Meopta customer service is amazing, though I have not needed any warranty work. It helps that the warranty center is on LI.
IOR Valdada 10x showed some dust on the internal surface of the ocular after several months of use, sent them a picture of it. They said to send them the scope, and I had it back in a week.
Havent been a fan of Leupold for years, as I dont feel the product or their service for the price is what it once was. But that is just me and my opinion.
