The original QD quick-release mount allows the reflex sight to be attached to the weapon immediately and removed just as quickly. The 1/3" Co-Witness mount is compatible with a Picatinny/Weaver rail.
The QD quick-release 1/3" Co-Witness mount will move the aiming pattern (dot) above the level of the fixed sights – hence the English designation "co-witness". If necessary, you can also shoot with fixed or flip-up sights that will be located slightly below the axis of the reflex sight.
You can remove the sight part from the mount, which is mounted here with screws, giving you a low QD mount. Another advantage is the fact that this original QD mount meets the AR-15 standard and is thus suitable for combination with long guns on this platform.
