Key Features to Look For
When you shop for a red dot sight, keep these important features in mind.
- Dot Size: Red dots come in different sizes, like 2 MOA or 4 MOA. A smaller dot is better for shooting far away. A bigger dot is easier to see up close.
- Brightness Settings: You need to see your dot clearly. Look for sights with many brightness levels. This lets you adjust for bright sun or dim light.
