I originally had an Athlon Neos on this Mas 36, but the scope wasn't quite what I needed for elk hunting. I upgraded to the Athlon Argos 4-20×50 and have been very satisfied with it. With the Argos, I have taken this 70-plus-year-old warhorse out to 600 yards with custom ammo and can bang a 15-inch gong with accuracy, clarity, and ease. The turrets, which were an issue with my Neos, are tight and accurate. I am considering buying an Argos in FFP for a Yugo 48 I have. Good stuff!!!
