Vortex always uses high density, low dispersion glass in their scopes, so the image clarity is top notch. Additionally, the lenses are coated with Vortex’s proprietary full multi-coating for maximum light transmission. Even in bad light, the Diamondback still produces a bright, high definition image.

At an affordable price, this is one of the better scopes available on the market, today. The no fog feature is an excellent option to have in the elements, which will ensure accuracy, every time.
- The Gear Hunt
This scope, in particular, is a simple one, void of superfluous gadgets. Instead of attempting to impress you with a novel-length list of average features, Vortex put their focus into performance and reliability. This scope doesn’t hold your hand through the hunt – it just excels at what it’s designed to do.
- Scope Reviews
The Vortex Diamondback 4-12×40 riflescope has great quality and very durable. The scope is solid and is highly resistant regardless of an unsteady weather. It is surprisingly lightweight and easy to mount and set up. It has excellent clarity. The scope is sharp and crisp and has a large field of view. Waterproof and fog-proof, a feature any hunter would require so as not to disrupt them from hitting their targets.

The dead-hold, BDC reticle uses a custom dot-design to compensate for wind corrections and holdover, making it a good choice when hunting at varying ranges. The scope utilizes argon for waterproofing, which also makes it fog-proof. The optics are multi-coated so that the view is exceptionally clear and sharp, even in the harshest of weather conditions.

You get an amazing reticle when working with this model. It is one of the best and should easily work for various applications that you might have. The reticle sub tensions are seen to be helpful for you to estimate the range of your target. You can also deal with wind correction and holdover. You should have better accuracy when using this type of model.

FOV is measured in feet at 100 yards and is amount of view you see through your scope from right to left at that distance. FOV is a function of the shape and contouring of the glass inside the scope rather than the size of the objective lens.
- Cali Gunner
Constructed in the highest quality aircraft grade aluminum, this Vortex Diamondback is incredibly durable, waterproof, shockproof and, thanks to its argon purged tube, fog resistant.

Image may lose sharpness when shooting while making use of magnifications. Lens may create some glare.

Hazy in low light
- The Gear Hunt
One of the only common complaints about this scope is that the parallax is not great after 50 yards.
- Scope Reviews
Adjusting the reset turrets may take more time than normal. This fact, however, does not apply to all types of rifles and does not make the Vortex Diamondback 4-12×40 riflescope any less good that others in the market.

The scope at 12X magnification sometimes has a little issue with glare compared to higher end scopes with better lens coatings. This was only noticeable when the sun was lower on the horizon, it wasn’t bad, but noticeable at times.

An Overview On Hunting Scopes

Each year approximately 15 million Americans participate in the sport of hunting. If you find yourself among them, you’ll need to make sure you have the proper gear. The second most important piece of equipment besides your hunting rifle is a scope. This tool allows you to narrow in on your target for more accurate results.

Before comparing hunting scope features, you need to ensure that the scope is compatible with your specific rifle. Once you confirm that it is, you can move on to the scope’s construction materials. You want a model that’s designed to last. One made of a high-strength aircraft aluminum is a good choice. Others have sealants that make them shockproof, fog-proof and rainproof.

Review the lens next. A multi-colored lens is best, as it eliminates glare and provides a higher light transmission than a simple blue light. Some models are equipped with as many as five illumination modes, so that’s another element you may wish to look for.

Check for easy-to-use wind and elevation adjustments. These are essential when it comes to helping your bullet reach the target. You’ll also want an eyepiece with quick and easy reticle focusing, so that you never miss a shot.

Don’t forget to take a look at the adjustable objective. Some models offer a range of 15 yards to infinity, while others have a starting range of just 3 yards. Long eye relief and an ultra-forgiving eye box are also essential, as you don’t want to put your eyes in unnecessary danger.

The Hunting Scope Buying Guide

  • Dirt and smudges can really affect how well you see through the hunting scope’s lens, especially if the lighting levels are low. Some scopes come with their own cleaning cloth. If your model doesn’t, you’ll need to look for a lint-free cloth that you can use to clean the scope. Starting with a soft-bristle brush is best, as this tool works well to dislodge any dirt or debris. Afterward, wipe down the lens with the cleaning cloth. It’s best to wipe in a circular motion.
  • Scopes that are more than just a little dirty may need an anti-fog liquid lens cleaner and a lens cleaning tissue to get the job done. Always apply the liquid to the cleaning tissue and then wipe down your lens. Never drip the liquid directly onto the lens itself. Go back over the lens afterward with a clean, dry, lint-free cloth.
  • While there is always the option to pay a gunsmith to mount the scope to your rifle, it is a task you can complete on your own. Start off by mounting the scope low and then checking that the eye relief doesn’t smack into your nose. Now you can align the base and tighten the screws to secure the scope. Finally, you’ll need to mount the rings, check the alignment and position the scope.
  • If you run into any trouble mounting your scope, check YouTube for step-by-step videos that you can follow. Sometimes seeing someone complete the task helps.
  • Size, construction materials and the number of features all come in to play when pricing hunting scopes. The CVLIFE Hunting Rifle Scope and the CVLIFE Illuminated Scope are among the most budget-friendly options. You’ll pay a moderate cost for the UTG BugBuster Scope, while the Vortex Optics Crossfire II Riflescopes is able to command a higher price.
