Co-witnessing a red dot sight allows you to use both the iron sights and the red dot on your firearm, offering backup aiming capabilities in case of red dot failure. This guide provides a comprehensive breakdown of how to achieve proper co-witnessing, covering different sight types and potential challenges.
Understanding Co-Witnessing
Co-witnessing means aligning your red dot sight with your firearm's iron sights, so both are visible simultaneously. This provides redundancy; if your red dot malfunctions (battery failure, etc.), you still have your iron sights for aiming. There are two main types:
- Absolute Co-witness: The red dot is completely enclosed within the iron sights' field of view. This offers the clearest view of both aiming systems.
- Lower 1/3 Co-witness: The red dot sits slightly below the iron sights' top edge. This provides a clearer view of the target through the iron sights while still allowing the red dot to be visible.
Choosing between absolute and lower 1/3 co-witness depends on personal preference and shooting style. Many shooters prefer the lower 1/3 co-witness as it allows a clearer sight picture through the iron sights, especially at longer ranges.
Steps to Achieving Proper Co-Witnessing
The process involves carefully mounting your red dot sight to achieve the desired alignment. This usually requires the use of specific mounting hardware (e.g., different height mounts).
1. Choosing the Right Mount: The height of your mount is crucial. Too low, and you won't see the red dot through the iron sights. Too high, and the iron sights will obstruct your view of the red dot. Manufacturers often specify mount height for co-witnessing, but you might need to experiment to find the perfect fit for your specific firearm and red dot.
2. Mounting the Red Dot Sight: Once you've chosen the appropriate mount, carefully and securely attach it to your firearm's rail. Ensure it's tightly fastened to prevent shifting during use. Consult your firearm and red dot sight's manuals for proper installation procedures.
3. Verifying Alignment: With the red dot mounted, look through the sights. Observe the relationship between the red dot and the iron sights. Adjust the mount height as needed until you achieve the desired co-witness. You might need to repeat this process several times to perfect the alignment.
Troubleshooting Common Issues
- Red dot too high: Use a lower mount.
- Red dot too low: Use a higher mount.
- Obstructed view of the red dot: Adjust the mount to center the red dot within the iron sights' field of view.
- Difficulty sighting with iron sights: Verify the iron sights are correctly aligned and that your eye relief is adequate.
Different Firearm and Sight Considerations
Co-witnessing can vary significantly depending on the firearm and red dot sight used. Some firearms might require specific mounts or even modifications to achieve proper co-witnessing. Always refer to your firearm's and red dot sight's manuals for specific instructions and recommendations.
Conclusion
Co-witnessing your red dot sight provides a valuable safety net, offering backup aiming capabilities if your primary sighting system fails. By carefully selecting the right mount and aligning your sights, you can ensure a reliable and versatile aiming system for a variety of shooting situations. Remember that practice is essential to become proficient with both aiming methods. Always prioritize safety and follow all firearm handling guidelines.
