I would highly recommend you to mount this scope on your gun if you want to enjoy quality images. This scope is equipped with an array of features considering its price range. The following are some of the things that make it outstanding.

Multiple Configurations:

Compared to many rifle scopes in its price range, this baby offers a wide range of configurations. This makes the scope versatile so you can use it on slug shotgun, muzzleloader, big game, varmint, and long-range shooting. You can use this scope when you are shooting at different ranges and achieve the desired results.

Fully Multi-Coated Lenses:

One of the main reasons why you should mount a scope on your rifle is to help you get a better sight. Therefore, there is no need to buy a scope with poor optics because it will not help you view your targets. In this regard, the Vortex Optics Diamondback 4-12x40 is equipped with fully multi-coated lenses that provide clear and bright images. It doesn't matter if you are hunting at dawn or dusk; you will always get quality images. On top of that, it offers anti-reflective images to help you locate your targets with ease.

Durable Construction:

This is a well-made scope that will serve you for many years. It features a durable and strong construction meaning that it can handle any outdoor condition. Additionally, the scope has waterproof and fog-proof performance to protect the internal components from damages. As a result, you can use it under any weather condition without compromising the image quality or durability. It is a solid one-piece unit that features a hard-anodized finish to offer users many years of great performance.

Dead-Hold BDC MOA Reticle:

Near the eyepiece of the scope, you will find second focal plane reticles. This type of reticle does not change in size when you adjust the magnification. The main benefit of using this type of reticle is that it will always have the same appearance. On top of that, it features a customized dot design that gets rid of guesswork on windage corrections and holdovers. These aspects make the scope ideal for hunting or shooting at different ranges where you need to estimate the holdover.

Fast-Focus Eyepiece:

The fast-focus eyepiece works together with the precision glide erector to provide you instant and smooth viewing experience. You can view your targets clearly, even when the condition is harsh.

Magnification And Objective Lens:

The magnification in a scope matters. The scope offers a magnification of 4-12x, which is pretty ideal for zooming your targets. It features special components.
