The PST is a great scope, I have two of them and love using them. The Razor is my preferred scope over the PSTs though for several reasons. Main reason is glass quality, the HD lenses they put in these things are incredibly bright and clear with no distortion or fuziness at all when properly focused. Plus you get 125 MOA or 36 MRADs of internal adjustment, this will take you a long way out there even if you don't have a slanted base. The zero stop is another feature I prefer on the Razor over the PST. While the stop works good on the PST, the Razor stop is like hitting a brick wall--it stops in exactly the right spot everytime. And the reticle on the Razor (EBR2B MRAD) is excellent too, it has elevation holdover and windage aiming points if you dont have time to make the adjustments on your turrets.Held one over the weekend. HUGE !! 35 mm tube is big. Glass looked really good, nice reticule. I liked the turrets and the clicks on the PST better. I really don't know what else to say but, buy three of the PST's instead of one Razor. And I say that with being a huge Vortex fan, I just don't see what you're getting for $2k versus the PST, besides that gigantic tube.
