1. Advanced adjustable systems

The Vortex Diamondback boasts and impressive level of customization. In particular, it features a parallax knob which allows for precise shots. It also has turrets which are easy to adjust. This ensures adaptability in a number of different situations.

2. Powerful reticle support

One can fit this scope with reticles. Of course that’s expected. But what’s extra impressive comes from variety of support. One can fit the scope with any reticles that properly fit sub-tension to angular value.

3. Reliable construction

It’s made of aircraft grade aluminum alloy. This in and of itself suggests a durable design. But method of construction matters as well. A multiple piece construction breaks apart with enough kinetic energy. The Vortex Diamondback’s single piece construction avoids that issue.

4. Strong haptic feedback

Taking time to check over equipment is time when one could miss a shot. The Vortex Diamondback solves this by offering solid haptic feedback. When one adjusts elevation and windage dials a click announces results. This means that one can make precise adjustments without ever needing to take eyes from the target.

5. Zero reset

The precision turrets offer a lot of advantages. But the zero reset after sight-in easily ranks among the best. Even better, it fits in a strong precision glide erector system. This helps ensure stronger and more accurate tracking. Additionally it helps for repeating shots. This type of repetition helps build skill.

6. Recoil tolerant

This goes along with single piece construction. But it bears special mention that it’s strong enough to handle any and all recoil. This makes it a perfect match for more imposing firearms. One doesn’t need to give it any special attention when using high powered options. This also means it’s easy to swap between one’s full collection.


1. Mounting area

Perhaps most notable issue comes from mounting area. The overall size of the mounting area on this scope might come in short. This can end up as an issue in some cases. Though in others, people might find the smaller size makes it easier for quick sets.

2. Jack of all trades style design

Another issue comes from the fact that it’s somewhat middle of the road. It tries to match almost any user’s needs. And for the most part this leads to something which can work in most conditions. However, this philosophy keeps it from really excelling too much in any rare usage condition.

3. Solidly mid-tier

One might consider a mid-tier price and mid-tier design as either compliment or critique. Here, one should note that it’s not a top tier piece. It’s solid and quite good for the cost. But it will suffer issues from not having top-tier construction. It’s one of those critiques which isn’t easy to put into objective statements. But usage in a variety of areas quickly makes it clear that it’s good, not amazing.

4. Somewhat opaque glass

Anyone who’s used a variety of different scopes can attest to differences in glass quality. It’s not enough to simply stand up to recoil. Glass design changes how a scope reacts to environmental conditions.

It also provides the window in which one decides on a shot. In this case that window might be a bit cloudier than one would like. It’s not really occluded. But at the same time it’s not the type of crystal clear display which one assumes from higher priced options.

This Vortex Diamondback 3 9×40 review emphasizes specs. But one needs to tie it all together. Everything points to this as a good fit for hunters. The main reason comes down to adaptability. It doesn’t showcase excellence in most areas. But it’s also not really weak in any area.

This adaptability matches perfectly with nature. One never knows how the natural world might change in short amounts of time. Likewise, the Vortex Diamondback 3 ensures one can keep up with those changes. However, using it in more stable environments wastes that adaptability. In those cases one might want to find more specialized specs.


The Vortex Diamondback 3 comes in at a reasonable price. It generally sells online for around $200.


In conclusion, this Vortex Diamondback 3 9×40 review provides a look at an interesting option. There’s one particular point that we’ve returned to again and again. That’s the fact that a Vortex Diamondback 3 is a solidly middle of the road option. It’s a fantastic scope when one is going through different environments.

For someone at a shooting range this might not be overly impressive. But someone out in the wild during a hunt doesn’t know what he’ll encounter. Thus, a scope like this can perfectly match those situations.
