Has anyone tried one of these, specifically the 4x16x44? Seems like my 22 year old scope on my 300Wby finally took a dump, it goes completely out of focus when I zoom in. Wanting a FFP and illuminated reticle; not wanting to spend over $400. This Arken is the only thing I've found, and it's only $210. Very happy with the other Arken I have; hoping to hear someone's experience with it before I spend the money. Can't find any reviews on this particular model.
