Reticle Size
The next thing to consider is the size of the reticle which is measured in MOA. The large MOA red dot sights are simple to spot in any lighting or weather condition.
But they lack the precision found in the smaller MOA reticles, especially at long ranges. If precision is what you are looking for, go for a sight that has a small red dot reticle of not more than 3 MOA.
Brightness Settings
The brightness settings in most red dot sights are adjustable to make the sight usable in different lighting environments.
Look for a sight that offers at least 8 brightness settings. Such a sight will be easier to use in a wide range of environments.
If you want a sight with dual day and night functionality, ensure that it has some of its brightness settings as night vision compatible.
Battery Life
Another thing to take into account is battery life. A red dot sight with a low power consumption will keep the battery running for a long period.
This will save you the high maintenance costs of battery replacement especially if you use the sight regularly. A long battery life is also a guarantee that the sight will not fail in the middle of use.
