The "lines" are IMO minor detail when hunting. If my eyes see right, the scope is variable LEICA Magnus, eiher 1,8-12x50 or 2,4-16x56. Those both scopes have very high quality optics. Their excellent light transmission and extraordinarily high contrast added with illuminated reticle and large scale of magnification makes them very usefull in many kind of hunting, from dusk till down. Scopes big size is one minus but you will get used to it quite soon.
