I've never owned a FFP, MIL Reticle , and Side Focus scope and tried an Athlon Argos BTR 6-24 x 50 knowing it was low end but seemed to have a lot of features for the $$. The Parallax Side Focus failed on its 2nd outing. I called the toll free number and explained the problem and it seemed they had a very small percentage of the same failure on some early scopes and advised me to return it. Within a week of them receiving the return, I received a new scope. The day after I received the scope they called me as a follow up. Looks like great warranty service.
