How To Choose a Red Dot Sight

Today, many amazing shots have been placed with the help of a red dot sight. If you want the experience the benefits that these multi-functional and iconic sighting tools have to offer, here are the most important things to consider when buying a red dot sight. Let’s take a look.

1) Reticle Size

The first thing to consider when looking to buy a red dot sight is size of the reticle. Since this optics are unmagnified, having a fine aiming point makes it possible to achieve the right balance between quick target acquisition and accurate shooting.

The reticle size is measured in MOA (minute of angle) and it varies in size from one model to the other. Generally, red dot sights with smaller reticles of 3 MOA and below are the best in terms of accuracy. They hardly obstruct the target to ensure precise shooting even at extended ranges.

Large reticles of 4 MOA and above don’t necessarily rule out accurate aiming, they just lack the precision of the smaller counterparts especially at longer ranges. Besides, they can easily obstruct the target especially if its small in size.

2) Brightness Settings

Red dot sights have adjustable brightness settings to enable use in different light settings. The more the brightness settings a red dot sight has, the better.

Whether you anticipate to use the sight for hunting, home defense or shooting, being able to dial down the rheostat to a point where the reticle contrasts with the target produces better accuracy. Besides, some red dot sights have their lowest brightness settings to be night vision compatible. As a result, you will be able to pair them with your favorite night vision gear.

3) Battery Life

Red dot sights that function without batteries are handy, but few in the market. Most are powered by batteries to illuminate the red dot and keep it visible in the different light settings.

It is vital to get a red dot sight with a high-capacity battery. It will help you concentrate more on the shooting knowing that the batteries won’t fail in the middle of use. A device that has a long battery life also has the added benefit of being economical to run and maintain.

4) Build Quality

Build quality is the next important thing to consider when trying to figure out how to choose a red dot sight. Just like any other optic, the build quality of a red dot sight determines its overall durability and performance.

We recommend that you get a unit that is crafted using the most hard-wearing materials. It will be resistant to the highest levels of abrasion and withstand wear and tear. A compact red dot sight that is optimized for durability also promises reliable performance in the most unforgiving terrains.

5) Battery Compartment

The battery compartment of a red dot sight is put on these three positions: top, bottom or on the side. For convenient handling, we recommend that you settle for a unit with either side or top battery compartment.

Such optics allow for convenient battery change when the sight is still mounted on the firearm. As such, the sight will still retain its zero even after you have removed and replaced the battery.

6) Size and Weight

Red dot sights come in different sizes and weight. Consider the kind of firearm you will be using the red dot sight with and choose a size that blends the best. If it’s a handgun, go for a red dot sight that is small in size to not affect its ease of concealment. Additionally, it is vital for it to have a lightweight design to not add any extra weight that can affect the balance of the firearm.

7) Weatherproof Construction

It is also important to buy a red dot sight that is built to be usable in all kinds of weather conditions. The tube should be sealed and filled with an inert gas to prevent fog build up when you use it in the rain or in cold environments. It is also important that you buy a red dot sight which performs in a reliable manner across a broad range of temperatures.

8) Magnifier Compatibility

Last on how to choose a red dot sight, consider compatibility with magnifiers. Adding a magnifier behind a red dot sight enables one to take shots at longer distances where it would be impractical to use the red dot sight alone.

In the current sphere of optics, there is a variety of red dot sights that are compatible with magnifiers. So, if you anticipate to use one for long range shooting applications, we recommend a unit that is magnifier compatible.
