Vortex Optics DBK-10019 Diamondback HP 4-16×42 Riflescope Review

This mid-range priced 3×9 small scope package has got to be my number one recommendation. You’ll be amazed by its quality brought by the well-known brand Vortex. This one-piece tube offers extremely clear lens, easily manipulated variable power ring, windage adjustment, and elevation adjustment. Its strength is even combined with its waterproof feature. It even includes a side focus/parallax adjustment that is easily accessible while keeping a trim profile and allowing optimal mounting height. This scope is highly resistant to recoil because it’s made of aircraft-grade aluminum, which is unquestionably stronger and lighter than previous steel tubes. If you’re looking for a 4-16x great optics that comes at an affordable price, then get your hands onto this scope.

Aside from what’s mentioned, you also get Extra-low dispersion (XD) glass which results to high resolution, crisp, and sharp images in exact colors. Because it’s XR Fully Multi-coated, it gathers more light than other scopes in its price range. It’s scale of reticle maintains the same ideally-sized appearance as well. Smooth magnification is offered by its Precision-Glide Erector System and fast focus is offered by its eyepiece that quickly responds. Re-indexing of the turret to zero after sighting in the riflescope is also possible through its Capped Reset Turrets. Another great highlight of this scope is its customized dot design which helps eliminate guesswork on holdover and windage corrections.

However, there’s a possibility that at 14-16x magnification power, you’ll experience a mirage problem. Also, some reviews mentioned that the reticles start to rotate on its own after taking many shots. You may also have struggles maintaining good eye relief but this scope is really good for hunting and shooting at varying ranges, especially where estimating holdover is a concern.

This is a lifelong investment for you and one of its optical features is the reason. Its scale of reticle maintains the same ideally-sized appearance. Listed reticle subtensions used for estimating range, holdover and wind drift correction are accurate at the highest magnification. Because it’s a single-piece tube, the alignment is maximized for improved accuracy and optimum visual performance. It also ensures strength which will be discussed later in this review.

Earlier I mentioned that the scope is waterproof. That is because its O-ring seals prevent moisture, dust and debris from penetrating the riflescope for reliable performance in all environments. Argon gas purging, on the other hand, prevents internal fogging over a wide range of temperatures.

Below are the specifications of the said scope:

This scope combines great with a single piece cantilever scope mount on an AR. The holdovers on the BDC reticle are great especially once you find a round that works well in your gun and you plan to stick with it and shoot often. Once you find your round you can use the LRBC app on their website and the hold overs are calculated for you and they work smoothly and continuously. In addition, the turrets track properly and move the amount stated per click, so there would be no trouble with adjusting.

This scope can handle the recoil from Winchester model 70 in 270 with your average shot around 200-300 yards and even at 400 yards.

Though the Vortex Optics DBK-10019 has extremely clear lens, you may encounter a slight distortion around the very periphery of the field view at the highest magnification, which is 16x. But as expected with Vortex scopes, the side focus adjusts easily and functions well. Even if you get into a little accident and it gets abused by the trees and rocks, it will hold zero perfectly. And that, my friends, speaks of its durability. You will not even have problems with fogging and condensing on the glass during cold, rain, and snow. You will surely be satisfied with the features and the performance of this scope because of its price and warranty.

The scope comes with a 4-inch sunshade, protective lens cap, and lens cloth. If you want more protection for the scope or specifically its lens because you don’t want to risk it, then you’ll really buy a lens cap even if it isn’t included with the scope. So let’s talk about the Vortex Optics Riflescope Lens Flip Cap Cover. It’s simple and also an effective rifle scope accessory by Vortex. It protects ocular or objective lens from damage and debris. It is very simple to install. It’s durable, rubber, hinged design flips back and lies flat when not in use. It may not always snap, but it will work as it should. The strength of build is of quality and is very good, too. The hinge also appears much more durable than other caps within its price range. You may doubt the elastic design, but it’s worth the try.
