Would not recommend - Athlon Optics Argos BTR GEN3 8-34x56 30mm Tube Rifle Scope, FFP

This is for the argos Gen3 8-34x56. I received the scope in perfect condition and everything works well but it will not focus. I have tried it in several different conditions,hot,cold, sunny, cloudy and nothing seems to work. The target is always blurry. I have many scopes,some cheap and some more but all of them focus better than this scope. There are much better options and many for less money. I was really hoping this would be be better.
