What Distance Is a Red Dot Sight Good For?
Many factors affect the shooting range of a red dot sight. Some of these parameters include daylight availability, the shooting environment, the size of the target, and more. The effective range of a red dot sight when not using magnification is typically 100 yards.
Should A Red Dot Be Zeroed?
Many benefits make red dot sights useful for a variety of platforms, from shooting sports to self-defense. Similar to a riflescope, a red dot sight must be zeroed properly for effective performance.
How To Zero a Red Dot Sight?
When zeroing a red dot sight, decide first on the distance you will zero at. A 50-yard zero is more practical when zeroing a rifle-mounted red dot sight. When zeroing a pistol mounted, a 25-yard zero is more appropriate.
You should take into consideration the firearm, its capabilities, and intended use, as these determine the right distance to zero your device.
Once you have determined the distance, place your zeroing target at that distance.
Then, choose your point of aim and shoot a grouping at the point of aim.
After that, gauge the distance between your point of aim and point of impact. Ensure you line up the point of aim with the point of impact.
The final step is to shoot another grouping to confirm that your zero is accurate.
