Factors to Consider when Choosing the Red Dot Sights for Air Rifle Hunting

With the market offering many red dot sights to choose from, here are some of the important features you need to pay keen attention to in order to get one that perfectly suits your air rifle hunting needs.

Size and weight

Size plays a critical role when it comes to compatibility between red dot sight and the air rifle intended to be used. The appropriate red dot sight is one that’s compatible with your air rifle. For hunting purposes, the red dot sight you choose should be lightweight and portable. This way, you will have an easy time traversing through thick woods and plains. The weight of the sight also matters because it contributes to the overall weight of the gun.

Battery life

Most Red Dot Sights for Air Rifle Hunting are battery-powered. Illuminated reticles in a rifle scope will appear black without the illumination, however, nothing is visible in a red dot sight without power. Red dot sights tend to have longer battery life but cold weather drains up the battery faster. When hunting in cold weather conditions, backup batteries at hand are highly recommended. Furthermore, many red dot sights have a battery life of about 10,000 hours, which is approximately 5 years. This means that you don’t have to worry about the battery is dead, but you should always replace them after one year or two.


Red dot sights are available in two basic styles; open or tube style. The open window design is a square-shaped window that is often more compact and low profile compared with the tube-style counterpart. It offers a wider field of view for shooters and by using two eye aiming method, there is less interference with your vision. Another good thing about open-style red dot sights is that they are lightweight and portable.

On the other hand, tube-styled red dot sights are often heavier, but more durable and protected. The good thing about them is that they are capable of withstanding more abuse and are more waterproof.

Durable construction

To ensure great performance and great value for money as well, the red dot sight that you choose should be capable of withstanding multiple bumps and falls along the way without getting destroyed. The body should be built from durable and sturdy materials. The sight should also be built of materials that are completely waterproof and fog proof, to ensure all-weather reliability. To ensure accurate target acquisition, the sight should also be resistant to recoil.

Type of reticle

With red dot sight, reticles don’t appear defined and sharp like in riflescopes. Instead, they look different from eye to eye as well as from one person to the other. No red dot will offer a crisp outline, therefore don’t worry about finding the perfect reticle when looking for a red dot sight.

Red Dot Sights for Air Rifle Hunting FAQs

Which is the ideal distance to shoot with a red dot sight?

Red dot optics are best sighted for 100 yards. At this range, you will clearly see the target and get that accurate shot. Accuracy after 100 yards will depend on the size of the target as well as the design of the optics.

Are red dot sights good at hunting at night?

Yes. Some red dot sights have different illumination settings that make them ideal for use at night, Red dot sights even have a slight advantage over the night sights because they work better with a focus on the target rather than focus on the sights.
