I have 2 of the SS 3-15x42 scopes and really like their functionality but the glass is not all that great IMHO. I can't compare directly to the Bushnell Elite Tactical 3-12x44 G2, but if its glass is as good as my Elite Tactical DMR 3.5-21x50, I would say it would be the clear winner if prices were the same.
Note, I am only a rookie in target rifles and higher end scopes so take my input with that in mind. I am interested in hearing what you decide and what others have to say.
I prefer to think of myself as a control enthusiast.
