Others FYI on Athlon Helos BTR GEN 2 2-12x

I am sorry to hear that. Mine fit well. Athlon should send you another set. Someone must have put the wrong size in with yours. Mistakes like that have been happening a lot recently it seems.

@Pumacarl It may be my vision. I believe that the diopter is backed out pretty far. This may be affecting fitment. I’m not sure. I measured the diameters of the scope on both ends before ordering the Monstrum caps. They normally fit well with an occasional loose fit on a lens on the borderline between two different sizes. I’m not sure if anyone made a mistake. The objective lens cover fits well.

I know this might sound hoaky, but in situations like this, I usually just cut tape to the width I need and wrap it to get the fit I need with the cap. If done right, you don't even notice it. It's better than loose floppy caps. Good luck!
