vortex crossfire vs diamondback
Alfred Mendoza

Whether your purpose is for hunting, surveillance, sniping, or tactical operations, it’s worthwhile to look into riflescopes. It can be pretty challenging since there are several variations in the market. Our team thought it would be good to make some comparisons. Read this review of Vortex Crossfire vs Diamondback to help you find that budget-friendly high-end scope for your firearm.

While both scopes offer 4-12x magnification, Diamondback has a wider field of view and better eyepiece focus mechanism, making it more suitable with moving targets. Crossfire II has a few models with an illuminated reticle, whereas the Diamondback series doesn’t have any.

Crossfire II is nitrogen gas purged while Diamond is argon gas purged. The elevation adjustment of Crossfire is at 50 MOA, while Diamondback 4 12×40 is at 60 MOA. The objective lens diameter of Crossfire measures at 44mm while Diamondback is at 40mm. Hence, the former lets in more light than the latter.

Crossfire II models are better for target shooting, range shooting, and sniping activity where long eye relief is important. They are exceptional for long-range shots, but they can’t handle heavy recoil.

Meanwhile, Diamondback models are much more suited for hunting and tactical shooting. As such, they work perfectly well with larger weapons and can withstand magnum recoil.

Key Features


Vortex Optics Crossfire II and Diamondback scopes are way more affordable than other high-end second focal plane riflescopes. They are of exceptional quality and performance with unrivaled warranty and customer services. Why would you purchase an expensive scope if there’s a cheaper alternative with an almost on-par construction and performance? The scope’s price range you are willing to pay for should be determined by your shooting purposes and the quality of the scope’s materials. Crossfire II series is an entry-level scope that is as equally good as Diamondback 4 12×40 for some purposes, but it’s cheaper.

Battery Life

Illuminated reticles are designed to enhance aiming precision in low light conditions. Vortex Optics Crossfire II have illuminated reticles powered by a CR2032 battery. The longevity of the battery depends on the brightness settings.

To preserve your battery, always turn off your scope when it’s not in use. But If you have a lot of reserves or if you’re on a surveillance mission, you can keep it running until it’s all spent. For your spares, you can mount a waterproof battery holder on your weapon’s Picatinny rails.

Parallax Adjustment

When a target and reticle are on a different plane within the scope, it can cause an optical illusion. Thus, parallax adjustment is needed to get rid of it to obtain maximum image sharpness of your aim. Vortex Crossfire and Diamondback 4 12×40 are both factory-set at 100 yards for a parallax-free experience. Most rifle scopes we’ve reviewed are set to be parallax error-free at 100-yard distance, appropriate for most big game hunting situations.

Ease of Use

One of the important things to consider in buying a scope is efficiency. Vortex Crossfire and Diamondback have simple construction, making them easy to install and use. The reset turrets are relatively easy to adjust. You don’t have to spend an unnecessary amount of time making any adjustments with the accessory. If you follow the instructions manual carefully, it’ll work just as it should without any hassle and glitches.

Image Quality

Vortex Optics Diamondback and Crossfire can provide a crisp, clear, and bright image of your target. Their fully multi-coated lenses are fast focusing. Many gun users claimed that Vortex Crossfire performs better at rapid locational target acquisition, which allows easy switching from one target to the next one. Meanwhile, Vortex Diamondback offers better clarity and brightness as well as a wider field of view.

Focus & Lens Clarity

Scopes with multi-coated lenses and multiple anti-reflective layers on all glass surfaces can increase the transmission of light, reduce glare, prevent distortions, and enhance the clarity of your images. Crossfire and Diamondback are fully multi-coated, which can provide a clear sight picture even at higher magnifications. Here’s a thorough discussion on how magnification works

If you’re shooting in poorly lit conditions, opt for a scope (e.g., Vortex Crossfire) with a larger objective lens to transmit as much light as possible so you can have a clearer view of your aim. However, if you’re walking long distances to search for targets, choose a smaller objective lens (e.g., Vortex Diamondback) as it’s lighter and can still give you a visible image.

Eye Relief

If your eye relief is good, the image should fill the eyepiece, and there’s no fuzziness or blurring on the edges. Note that the higher the magnification, the lesser is your eye relief. Most standard scopes have an eye relief between 3’’ and 3.5’’. Higher recoiling guns need lots of eye relief to prevent any injury on the shooter’s eye or face.

Vortex Crossfire vs Diamondback: Which one has larger eye relief? Crossfire offers an eye relief 3 .9’’ to 4’’ while Diamondback offers 3.1’’ to 3.2’’. Vortex Crossfire series is often preferred by shooters who wear eyeglasses. Larger eye relief is good but at the cost to your exit pupil and field of view.
