Most Helpful Negative Review Best bang for buck
IMO this is the best scope for the money and even surpasses more expensive scopes. Highly recommended. Pros: By far the best piece of glass for the money Cons: Realy for what you pay for there are no real downsides

Absolute Trash

by KH, Verified Owner from ID, United States Written on June 20, 2025
Showed up to a combat veteran bear camp and attempted to zero, went through a whole box of ammo as the reticle danced around. had to use someone else's equipment since it's apparent that vortex scopes are a total disappointment. "QUALITY CONTROL?" �

eye relief is trash

by bwalke5, Verified Owner from LA, United States Written on January 28, 2025
I hate this scope. The relief is horrible. Mounted on my son’s deer rifle and swapped it out for a leupold I had on a different gun MID SEASON. That’s how much I hate this scope. Not sure what to do with it now guess I’m stuck with it.
Pros:
  • None
Cons:
  • Eye relief is horrible

great scope

by RagingHillbilly, from NC, United States Written on April 14, 2024
Great scope for the price. Replaced an old 4x on my 336 with Weaver see thru base. Yes, a little overkill but my old eyes need it. Glass is clear and crisp with good eye relief. As with my other Vortex scopes, this is another great one. Highly recommend this scope.
