Red dot sights for AR 15 often offer a wider field of view than that of a tube style scope. It means that you can acquire any targets at longer distances.
One thing to remember: the magnification controls the field of view that a tube-style scope amplifies. The tube style scopes for AR 15 limit the usefulness of light weapons at shorter ambit shootings.
Additionally, the red dot sights do not have any magnification great for short and medium distances.
Your shots’ accuracy depends on your AR 15 red dot sight’s weight. A heavier unit might possess a bearing with your handling and grip. A lightweight red dot sight helps you control everything without any difficulty.
Weight is not the only factor to consider. The best red dot sights for AR 15 come in many sizes. Some are easy to adjust. However, it is wise to consider your weapons’ size and how much space available.
1MOA (minute of angle) is equal to 1 inch at 100 yards. Red dots with 4 or 5 MOA are ideal. Smaller red dots mean that it takes a longer time to find your target and take shots.
