The Razor AMGs are a totally different line than the PSTs, being American made and well over twice the price. I'm sure the AMGs aren't replacing the Razor Gen IIs either, as Vortex rolled out some new reticles and a new pricing structure for the Razor Gen IIs at Shot 2019.
I suppose they are probably just clearing out old stock. Either way, those are pretty killer deals on the Razor Gen IIs, $50 better than the best "phone call only" pricing I've been quoted on them, from a place known to give the best deals to boot.
I've gotten used to image quality and features on my AMG, and now have the urge to upgrade the scope on my main AR as well... this could get expensive. I did think that the PST Gen II I got behind (supposedly a big step up from the Gen I) was a nice scope for the money, I'm pretty tempted at that price.
