Wondering if anyone out there has experience with Vortex Optics Viper line of scopes ? Considering purchasing either the HST or PST 4-16 model. Would prefer the 50 mm so would opt for the PST but really do not need the electronic reticle. Currently using the Leupold Mark IV LRT model scopes. Hard to beat. Wondering do the Vortex scopes come close to Leupold glass ?
