Not so sure you voided the warranty. On my last GPR I was having a problem with the lock. I had taken it apart and modified it to try and get it to work. It still wasn't right, so I called Lyman to explain it all. I had to get to the gunsmith to get satisfaction, but when I did he was a nice guy and really wanted to help.

After a long conversation he agreed something strange was wrong with the lock, and sent me a new one.
