Red Dot Sights: The Rise of Risers with "Coch"

Published on July 22, 2023
Duration: 11:08

This video from Tactical Hive, presented by 'Coch', details the evolution of red dot sight height on firearms. It explains how early setups like the Aimpoint CompM2 on a carrying handle provided a high bore axis, while later iterations moved to lower third co-witness. The discussion emphasizes the importance of optic height for effective use with night vision devices and addresses the trend towards taller risers like those from Unity Tactical for better integration with nods and a more natural shooting posture.

Quick Summary

The trend towards taller red dot sight risers, like those from Unity Tactical, is largely driven by the need for better integration with night vision devices (NVGs). These risers allow for a more natural shooting posture when using NVGs, reducing fatigue and improving situational awareness in low-light conditions.

Frequently Asked Questions

Why are taller risers becoming popular for red dot sights?

Taller risers are increasingly popular for red dot sights primarily to improve compatibility with night vision devices (NVGs). They allow shooters to maintain a more natural, heads-up posture when looking through NVGs, reducing fatigue and enhancing situational awareness during low-light operations.

What is 'lower third co-witness' for red dot sights?

Lower third co-witness means that when using a red dot sight, the iron sights are visible in the lower third of the optic's window. This setup allows for faster target acquisition with the red dot while still providing a backup sighting system that doesn't obstruct the primary aiming point.

How did early red dot sight setups differ from modern ones?

Early red dot setups, like the Aimpoint CompM2 on a carrying handle, were often mounted very high. This allowed for a good view of the red dot and the ability to transition to iron sights by simply lowering the head. Modern setups, especially with NVGs, also favor higher mounts but for different ergonomic reasons.

Does optic height affect bullet impact?

Yes, optic height affects bullet impact due to bore offset. The distance between the bore of the firearm and the optic's line of sight creates a difference in point of impact, especially at closer ranges. Understanding this offset is crucial for accurate shooting, regardless of the optic's mounting height.
