I have a Timberline it is a good clear scope. When I moved it to far left and then back right it did not move until I banged the scope. Sorry Burris.
I called them, I was told the grease get dried out. It holds zero okay. It works for what I want. Burris is not afraid to tell the truth. I like that about them. You get what you pay for. Burris is AAA in my book.
