Anyone had/have one of these. My .308 just got one on it as a replacement to the failed Nikon and Weaver it used to have. The Nikon's o-rings gave out and now it fogs, then the weaver is just old (El Paso) and can't hold zero. At Gander it was between the Banner 1.5-5 vs the Simmons and i think i chose wrong after checking the midwayusa ratings of each, Not that the SImmons isn't bad it that the Banner got 4or5 star rating while Simmons got an average 3 stars
