Red Dot Sight for Pistols, 21mm Picatinny Rails

The brand's mission is to create the clearest and brightest optics, empowering you to become a skilled sharpshooter. Enjoy the thrill of shooting and the fun it brings.

The Kalkal red dot sight is designed for close-quarter engagements with fast-moving targets, performing reliably in any condition and environment for your outdoor activities.

In case you encounter any issues, please follow these guidelines:

1. If the sight cannot be turned on, ensure the battery is correctly installed and not reversed in the battery compartment, or replace the batteries.
2. If the mounting is loose, you can tighten it using the included Allen wrench according to the provided instructions.
3. If the elevation or windage adjustments cannot be made, first loosen the locking screw, then adjust the elevation or windage as needed.
4. To adjust the point of impact upward, turn the elevation adjustment screw counterclockwise.
5. To adjust the point of impact to the right, turn the windage adjustment screw clockwise.

The anti-fog coatings on this reflex sight allow it to quickly clear up when faced with rapid changes in humidity or temperature. If the rail mounting becomes too loose, causing the sight to slide back and forth, follow these steps:

1. Remove the sight from the rail.
2. Tighten the quick detach mount.
3. Use the included wrench to twist the nut that controls the tightness of the quick detach mount.
4. Turn the nut clockwise to tighten the base.
