Cowitnessing a red dot sight with your iron sights offers a significant advantage in shooting, providing backup aiming capabilities should your electronic optic fail. This guide will walk you through the process, explaining the different methods and considerations for successfully cowitnessing your red dot.
Understanding Cowitnessing
Cowitnessing, in the context of firearms, refers to aligning your red dot sight with your firearm's iron sights. This means that when you look through the red dot, you can also see your front and rear iron sights within the red dot's field of view. This setup provides redundancy: if your red dot malfunctions (battery failure, damage), your iron sights are immediately available for accurate shooting.
There are two primary types of cowitnessing:
1. Absolute Cowitness:
With absolute cowitness, your iron sights are fully visible, even when the red dot is on. The iron sights are essentially "in front" of the red dot, appearing clearly through the window. This offers the clearest and fastest transition between red dot and iron sights. However, it often requires a higher mounting solution for the red dot, potentially affecting cheek weld and overall ergonomics.
2. Lower 1/3 Cowitness:
This method positions the iron sights slightly below the red dot's window. The top of your front sight post will be visible just below the red dot's reticle. This provides a slightly lower profile, often resulting in better ergonomics for shooters with shorter necks or who prefer a lower mounting position. The transition to iron sights requires a slight adjustment in aiming, but it still provides a viable backup.
Choosing the Right Cowitnessing Method
The best cowitnessing method depends on several factors:
- Your firearm: The type of firearm, its sight radius, and the availability of mounting options will influence your choices.
- Your shooting style: Consider your preferred shooting position and cheek weld. A lower 1/3 cowitness might be preferable for those who prioritize a more compact setup.
- Your red dot sight: Different red dot sights have varying window sizes and mounting heights, affecting the type of cowitness achievable.
Steps to Cowitness Your Red Dot Sight
The precise steps will vary based on your specific firearm and red dot sight. However, the general process includes:
-
Mount the Red Dot: Securely mount your red dot sight using the appropriate mounting hardware and height. Consider which cowitnessing method (absolute or lower 1/3) you prefer based on the factors mentioned above.
-
Zero the Red Dot: Zero your red dot sight at your chosen distance. This is crucial for accuracy with both the red dot and iron sights.
-
Check the Cowitness: Look through the red dot. You should see your iron sights clearly, either fully (absolute) or partially (lower 1/3). Adjust the mounting height if necessary to achieve your desired cowitness.
-
Test and Adjust: Test your setup at the range, firing with both the red dot and iron sights. Make adjustments as needed until you're comfortable and confident transitioning between the two.
Maintaining Your Cowitness Setup
Regularly check and maintain your cowitness setup. Ensure the red dot remains properly zeroed and securely mounted. Over time, the zero may shift due to recoil or other factors, so regular testing is essential.
Conclusion
Cowitnessing your red dot sight enhances your shooting capabilities by providing a reliable backup aiming system. By carefully considering the different methods and following the steps outlined above, you can successfully set up and maintain a cowitness system that improves your overall accuracy and readiness. Remember that practice is key to mastering the transition between your red dot and iron sights. Spend time at the range to build proficiency and confidence.
