Ok here is the deal, I have a mk4 8.5-25x50 M5 turrets on my TRG22 and love it so far. I recently got some time behind a viper pst 6-24 FFP I honestly could not see any difference between the leupold and the vortex. Now If I sold my mk4 I could get a viper and have some extra money. Now here is the question would you sell the mk4 for the viper? and if yes or no why?
