Hi, I'm trying to stop my choice on a budget FFP MRAD reticle spotting scope for shooting. I Think that my 3 options would be: Vortex Viper HD 20-60X85mm with the eyepiece reticle 33.5X fixed SightMark Latitude 20-60x80 XD Tactical Latitude Spotting Scope Bushnell Legend T-series 15-45X60 These are all at the same price range. I want to choose on a general perspective of quality and warranty. Any opinions? Thanks!
