In most of the case, you should go for red dot sights with a reticle that you could comfortably use. Stay away from complicated reticle pattern because their features could impair your vision and serve as distractions in critical moments. Generally speaking, the size of the dot should correspond to the anticipated shooting distance but you must be able to distinguish it from the target.
- Brightness Level
Since virtually all red dot sights have the same magnification power of 1x, the brightness level of the sight is an important factor to consider. The dot of the red dot sight must be bright enough so you could spot it in daylight without difficulty. However, the dot brightness should also not reach a level that you find it hard to clearly see the surroundings. In the case you feel the color red is too bright in every light condition, it’s best that you choose a green dot sight.
Types Of Red Dot Sight
There are 3 types of red dot sight you could come across: Reflex, Holographic and Prism. Each of the sights possesses unique characteristics which make it essential to know which type is suitable for your situation.
- Reflex Sight
For most of the time, reflex sights could be classified into 2 styles: Exposed and Tube. In exposed sights, the aiming reticle is projected from the rear of the sight on to a single lens which reflects back to the shooter. The working principle of tube reflex sights is quite similar with the exception that they use 2 lenses instead of only 1.

In term of cost, holographic sights are quite expensive compared to other types of red dot sight on the market. As a result, this type of sight is mainly employed by people like soldiers and competitive shooters who view accuracy is the number one priority
- Prism Sight
While other types of red dot sight often utilize lenses, prism sights use a prism and they are comparatively compact. Furthermore, a standard prism sight could offer some magnification power which should come in really handy if you want to engage targets at long distances. On the downside, you have to keep your eyes near the optic in order to receive a proper target image. About the cost, prism sights are more expensive than reflex sights but the average price has been on the decline. In conclusion, prism sights are suitable for shooters with average skills or people that want to shoot at extended ranges.
Battery Free Sights Vs Electronic Sights
As the names suggest, battery-free sights don’t use battery to power up the dot which means there is significantly less room for failure. In these sights, the dot is generated by fiber optics or tritium beta lamps so there is no way to manually adjust the brightness level. If all you need is a robust and straightforward red dot sight, you should consider getting a battery-free model.

Depending on the power consumption and battery capacity, an electronic red dot sight could work between 100 and 1,000 hours without interruption. Certain sights are equipped with a handy auto shutoff function in order to conserve battery life in case the owner forgets to turn them off.
