Ran into exactly the same thing! Buddy had one on an AR, it fell over when he got into his safe oneday. Never saw a mark on anything, didn't realize it was bent. We took it and 3-4 others out to the range one day to make sure everthing was sighted in. He wasn't even hitting the paper. I was sitting at the table next to him with the spotting scope, looked over to him after the 3rd round...what the !!!! The scope took a big nosedive, he hadn't noticed it when he checked it over. He sent it in to Burris with an explanation. They said they'd fix it! Didn't hear from them for a few weeks, called them, they said they were waiting on parts. They called a week later, said they couldn't fix it and offered to sell him a replacement for cost. So, he ended paying a fair amount less for a 4.5x14 than it would have cost him anywhere else....not bad when it was his fault. Greg
