Vortex Diamondback riflescopes completely change the rules when it comes to "you get what you pay for." Due to the solid one-piece aircraft-grade aluminum alloy construction, Diamondback scopes are virtually indestructible and highly resistant to magnum recoil. Argon purging puts waterproof and fog-performance on the checklist. Crystal clear, tack sharp images appear in the cross hairs with the fully multi-coated optics. You would expect a feature-heavy scope like the Vortex Diamondback to cost an arm and a leg, however, it doesn't. Enjoy Diamondback scopes for less than you'd expect!

While Vortex Diamondback riflescopes are equipped with many features, these scope accessories will take your scope to the next level. From scope rings to lens caps, EuroOptic has a wide selection of accessories that will be sure to meet your needs.

This is a phenomenal product. Very clear glass. Tactile and audible clicks on the windage and elevation knobs. I really like the reticle. I put this on an H&R Ultra Varmint rifle in .223 and plan on doing some hunting with it. The 3-9X is a good combination of magnification, field of view, and eye relief. The eye box is plenty enough for me and it is really easy to dial in the focus. I am very pleased. This was my first purchase from EuroOptic. I will definitely buy again. Thanks!

I purchased this optic as a value option for a 22lr and am happy with the performance.

This scope is an absolute bargain when it's on sale. Crystal clear, excellent clarity, and made in the Philippines. It's so good, I bought a bunch of them to replace existing. I highly recommend this scope.

This scope is really quite nice for the price (especially on sale). It's hard to compare since most of my other vortex scopes are PST or Razor(s) and my other low power scopes are mostly Zeiss. However for a daytime scope I couldn't be much happier. Wish the reticle was a few mills larger to fill up the whole scope but that is a nit pick. I would definitely buy again if I needed a low cost scope. For most hunting situations you simply do not need the big, heavy and high powered scopes. I shoot 500 yards with a 10x all the time and shoot MOA or less. Most hunting shots are 175 yards or less, so this is plenty!!!

Thought the optical quality would've been better. Not saying it is bad, but I think my $200 Bushnells have glass that is just as nice if not better. Like the reticle though and need to play with the turrets as I'm use to the more simple capped windage and elevation turrets. For the sale price, it was a good buy.

So far I have been pretty impressed with this scope. I really like the reticle it has. Turrets seem okay, they have a little bit of slack but not bad for the price point. Scope clarity seems to be very good. Would buy again.

Yes, there’s better optics without a doubt. However, for the price this scope is worth it and then some. Mounted on my Remington 700 chambered in 6mm Creedmoor and managed to zero in about 6 shots @ 100 yards (1/2 MOA). I was skeptical at first because of the 1” tube but it definitely didn’t disappoint. I was able to break it in on a 300lb boar at 120 yards which dropped on impact by putting it just behind its ear. Highly recommend!

I’m a huge fan of Vortex optics. I own about 10 different scopes and sights from them for everything from squirrel hunting to race handgun red dots to 1000 yard precision rifles. Vortex has great quality and price paired with the lifetime no questions asked warranty.
