We sell MeOpta and the offer GREAT glass. I have really wanted to try one of the 4-16x44 but I do not care for the turrets and the limited elevation. Another thing was the reticle is too thick for me. The Zeiss Conquest have nice glass also but limited elevation and thick reticles also. Really if you what to upgrade I would recommend looking at Nightforce they offer great glass, great reticles, and great mechanics.
I do not feel the MeOpta would be an upgrade for a long range scope
