If I was going to drop the money on a “buy once, cry once” scope, PA is not my idea of a company I’d do that with. PA has been a lower tier optics company for quite a while, and it’s only recently that they’ve started delving into the upper optics tier with their Platinum/PLx series. Keep in mind that it’s an OEM scope, meaning that PA is having the scope made by LOW of Japan. From my experience, the PLx is optically similar to the SigSauer Tango6 scopes. Not a bad scope by any means, but I feel like it’s a generation behind the Vortex Razors in terms of optical quality. The one PLx (1-8x) and every Tango6 I’ve looked through felt like a Gen1 Razor. At that point, just go buy an actual Gen 2 Razor for a few bucks more. The Vortex is a proven performer, so when you say “buy once, cry once”, the only reason you’d have to get rid of a Gen2 Razor is because there’s new, better Gen3 Razor, or because you’re upgrading to an Alpha tier scope like NF ATACR, S&B or ZCO.
Otherwise, look into options like the Leupold Mark5 or Burris XTR-III. The new Burris XTR-III 5.5-30x56 is $1529 over on SportOptics, and it’s a new generation of scope that Burris has been perfecting. Something with a better track record than PA. I had a chance to look through a new XTR-III, and it looked a lot better than the Sig Tango6 scopes I’ve looked through. I looked through a Gen3 Razor 1-10x at the same time as the XTR-III, but it was too much apples-to-oranges with the scopes to make a fair comparison. I didn’t have a Gen2 Razor to compare, but the XTR-III looked pretty close or similar to the Gen2 Razors I’ve looked through.
But this is all subjective to the user at the end of the day.
Magnification is something you have to be careful of. As you increase top magnification, you need to increase the optical quality of the scope. Getting past 25x really starts demanding high end glass, and fortunately the quality of glass we’re seeing now is allowing 25x or higher to be more viable. Still, you are going to see major differences in something like a PLx versus the Gen2 Razor, and from those there’ll be another step in quality when you go up to the higher tier scopes like NF, S&B, ZCO, Kahles, etc.
