I have about 15 Burris 3-12X BPlexes on my XPs, Encores, Contenders from .223 to .375/.284, some old, some new, for the last 15 years. My total number of problems has been exactly ONE. The crosshairs stopped responding to movement on a .309 JDJ. Burris fixed it-no charge. That was about 6 years ago. I'm totally sold on this scope until someone makes a better long range handgun scope.
