Factors to Consider when Choosing the Best Red Dots for AR 15
When choosing the best red dot sight for an AR-15, consider the following factors to ensure you pick the one that suits your needs, preferences, and shooting style.
Dot Size
The dot size is measured in MOA (minutes of angle), and it determines the coverage area on the target. 1 MOA reticles are deal for precise shooting and longer distances, 2 MOA for close-quarters engagements, and 3-4 MOA for faster target acquisition in dynamic situations.
Brightness Settings
