So I just ordered a "Nautilus" side focus wheel for my Athlon Argos 6-24x50 from Scope-Werks. Nicest wheels I've ever seen! Eric Sansers is the owner. I told him Athlon does not make a side wheel for their scopes. I had to send him numerous pics & measurements of my rifle before he sent me a cad drawing of his design. It looks awesome! It isn't cheap...$142.00 with shipping (what is in this sport), but this is a totally custom piece! If you guys are looking for something cool for your rifle, take a look, I highly recommend him!
