RE: blown scope, lead sled to blame?
That Burris Signture scope is a good quality scope. I am pretty sure Burris will stand behind their warranty, but as you know sending it in will still be a pain in the a**.
A lot of people have blamed the lead sled, and as I posted earlier I do not like them myself. However I have seen a lot of good quality scopes have trouble on top of MZ's over the years. It is probably impossible to find out exactly what caused the failure, but as long as you get a new Burris then that should help. Do you have the one that has the "reticle lock" on it?? I think that would be a great feature on a MZ scope.
I have a Burris scope on one of my MZ's. However I have the one with the Ballistic Plex reticle. You should try that reticle it works great on a MZ. Tom.
