Technically any Bushnell dealer can warranty it for you. If its something we sold then we usually do an over the counter exchange if we have it in stock. If it isn't one of ours or it isn't in stock then we file a warranty claim with our rep and they ship us another scope or similar model if it is discontinued.
Lots of companies handle warranties that way. We destroy the item, send them a picture if requested and they credit or replace the item. It is a lot simpler when there is a dedicated warranty centre for a company but this is how they now handle it since the warehouse moved to the US.
