I love the Vortex.
I gave myself a $1k budget and test drove all the mainstream optics out there and still ended up with the lowly $499 optic

. In the end the Vortex had all the options I wanted MOA/MOA reticle, Illuminated reticle, 1-4x magnification,tactical turrets for easy windage and elevation adjustments, a reticle able to range with and use for quick holdover without having to touch the turrets. The lifetime warranty was icing on the cake. I've shot about 500 rounds through it so far and dropped it once or twice

and the zero is holding strong. The glass is super clear as well.
Can't say enough good things about the Vortex Viper PST.
