Burris Black Diamond adding turrets?
A friend of mine has a Burris Black Diamond. He is thinking on rebarreling the rifle to a 260 match. The optics he has on the rifle don't have any turrets. Which option is better to add aftermarket turrets and if so which ones? Or just sell the scope and purchase a new one. I am uneducated in Burris's repeatability and aftermarket turret options.
