I searched and could not come up with anything. I read over the years leupold would convert a var-x3 30mm tube scope that has tactical knobs to m1 knobs. Are they still doing that conversion? Anyone had one done recently? I looked on the site and its different then the old site i read it on also. I may doa TMR recticle change also. What is a vx3 LR 30mm tube 4.5x14x50 mildot worth in good shape these days? Also is there a big deal with the indexed or not deal they started duing right before the mk4 came out i believe it was? is this something that can be upgraded if necessary?
