So what brand do you buy? The Viper PST is not Kahles, S&B or Nightforce quality. But it does compare well to Leupold and Burris IMO. Color blindness can also effect ones's opinion about a brand of scope. Each manufacturer uses different coats and if you suffer from even a mild form of color blindness, that can affect your judgment/opinion about the quality of the glass in a scope. I don't have color blindness. The Razor is better glass. But it's heavier and three times the cost. My Gen I Razor is the best glass I own. The Gen I Viper PST in 6-24x50 FFP is good value for the glass and the warranty. IMO you'll pay more for another brand with similar FFP specs that's not made in China. I don't buy scopes made in China. To really know what you're getting, you need view/judge a scope outside in full sunlight plus when the light is getting low. I've look through a lot of scopes at ranges. Vortex's Viper PST and Razor line of scopes offer good quality for the money compared to other brands.
