I'm planning to order this system for an Athlon Ares G2 spotter. Has anyone had any luck finding the right one to fit? They don't currently make one for an Athlon. The eyepiece diameter is 55.7 mm on this scope. Ollin says the closest one made is 55.85 which is for a Leupold SX4 spotter. I'm thinking I can probably make it work. Even if I have to use some kind of filler tape or maybe a chunk of bike inner tube to snug it up. Any thoughts?
