I recently found out that it is possible to send in used scopes to Burris to have them retro fitted with a new reticle. I have the handgun 3-12X with the regular duplex and I am curious if anyone here has used this scope with the balistic plex. I plan to use this scope on a 223 for rock chucks. The scope is not on the barrel yet, so I figured if I'm going to send it in I may as well do it now. What do you guys think? What will it cost?
