I called Blazer USA. They didn't ask me about purchase location or warranty or anything. They told me to send it in to them. I sent it to them the last week of April, 2019. I received an email from them saying they received it, I received another email, a couple weeks later saying it made it to Germany. I received an email earlier this week saying it was back from Germany at Blazer USA. I received the scope back today (7/17/19). They included a nice letter listing the work done (picture attached).
