Choosing the right optic for your firearm is crucial, but equally important is how you mount it. A poorly chosen mount can lead to inaccurate shots, discomfort during use, and overall frustration. This is where co-witness riser mounts come into play. This guide will explore everything you need to know about co-witness riser mounts, helping you make an informed decision for your specific needs.
What is a Co-Witness Riser Mount?
A co-witness riser mount elevates your optic above the firearm's receiver, allowing for a clear sight picture through the optic while simultaneously maintaining the ability to use the iron sights as a backup. "Co-witness" refers to the ability to see both the optic's reticle and the iron sights simultaneously. This is especially valuable in situations where your primary optic malfunctions or the battery dies.
There are several types of co-witness configurations:
-
Absolute Co-witness: The iron sights are perfectly aligned with and visible through the optic's reticle. This provides the clearest and fastest sight picture using your iron sights.
-
Lower 1/3 Co-witness: The iron sights are visible below the optic's reticle. This allows for a quick transition to iron sights if needed while still providing a clear view of the optic's reticle for primary aiming. This is the most common configuration for many users.
-
Higher Co-witness: Offers a higher sight picture, beneficial for certain optic and weapon combinations, but often sacrifices the ease of transitioning to iron sights.
Why Choose a Co-Witness Riser Mount?
There are several compelling reasons to opt for a co-witness riser mount:
-
Backup Sight Capability: The most significant advantage is the redundancy provided by maintaining access to your iron sights. If your primary optic fails, you still have a reliable aiming system.
-
Improved Sight Picture: A riser mount can improve your sight picture, especially with optics that sit low on the receiver. This can lead to faster target acquisition and more accurate shots.
-
Enhanced Ergonomics: A higher mounting position can improve the ergonomics of your weapon, making it more comfortable to use, particularly with certain body types and shooting styles.
-
Versatility: Co-witness riser mounts offer versatility, allowing you to adapt your setup to different shooting situations and preferences.
Factors to Consider When Choosing a Co-Witness Riser Mount:
Selecting the right co-witness riser mount requires careful consideration of several factors:
-
Optic Type and Size: The size and dimensions of your optic will dictate the height of the riser mount needed to achieve your desired co-witness configuration.
-
Firearm Type: Different firearms have different receiver heights and rail systems, influencing the compatibility of various riser mounts.
-
Material: Riser mounts are typically made from aluminum or steel. Aluminum offers a lightweight solution, while steel provides enhanced durability.
-
Height: The height of the riser mount will directly impact the co-witness configuration. Carefully choose the height to achieve your preferred absolute, lower 1/3, or higher co-witness.
-
Manufacturer and Quality: Reputable manufacturers like Midwest Industries, Scalarworks, and ADM offer high-quality, reliable riser mounts.
Installation and Maintenance:
Installing a co-witness riser mount is typically straightforward, usually involving attaching the mount to the firearm's rail system. Consult the manufacturer's instructions for specific installation procedures. Regular inspection and maintenance, including cleaning and lubrication, will ensure the longevity and reliability of your mount.
Conclusion:
Co-witness riser mounts offer a valuable upgrade for many firearm users, providing increased versatility, improved sight picture, and critical backup aiming capability. By carefully considering the factors discussed above and choosing a high-quality mount from a reputable manufacturer, you can significantly enhance your shooting experience. Remember to always prioritize safety and follow all applicable firearm safety regulations.
