Am a Burris fan and have them for years. I have the same scope as you and I have not liked it since day one. The focus was off to me from the get go. Sent it in twice for that both times said nothing was wrong. Then all the sudden out of the blue it would not hold zero and so I sent it in this time makes three times in really about three years. This time they say repairable and sending a new one. Its been junk since I bought it. Gonna call in the morning to see if I can replace it with another model.
