Ade Advanced Optics 6MOA RD3-019 Stingray Micro Red Dot Sight for Optics Ready Pistol, Black

The ADE Advanced Optics RD3-019 sensor-activated red dot fits all pistols with optic cuts for Trijicon RMR, including aftermarket slides such as Rockslides, Polymer80, and PSA that has an optic cut for Trijicon RMR Pattern.

Efficient Design

Ade Stingray is designed to be the smallest and lightest red dot to fit any pistol mounting plate/slide/cut that is compatible with Trijicon RMR/SRO, both type 1 and type 2 RMR, Holosun 407C/507C/508T footprint red dots. The overall length is around 15-20 percent shorter than other major red dots on the market. The shorter design allows this sight to be able to sit into all optic cuts, plates, and adapters that are designed for RMR footprint. For some optics-ready pistols with a larger optic cut, there might be a gap between the rear of the Stingray and the pistol's rear iron sight. 


ADE Stingray created an iron sight curve at the end of the body and also added two white dots on the curve. For the rear part of the red dot to become a backup iron sight. With the ultra-short design, the red dot provides a distance and gap on some full-size optics-ready pistols, to give enough distance to be a co-witness backup sight, in addition to the LED dot and pistol-equipped iron sight. For non-optics-ready pistols that need to use an optic plate/adapter to replace the pistol manufacturer-equipped rear sight, ADE Stingray's rear white dot will act as a pistol factory original rear sight for co-witness. Just like RMR competitors, It does not have an on/off power button. The light turns brighter or lower automatically. If you do not use it, put the provided rubber cover on it, then the sight will be ‘sleeping’ in a very low power mode. Comes with screws for several Optics Ready handguns. Does not come with any mounting plate such as a picatinny mount or plate made for a specific handgun.

Power Friendly

Hard-coated aircraft aluminum and multi-coated glass. Not a plastic body with a polymer lens. ADE Stingray red dot sight is always powered on and features an auto-dimming sensor that regulates proper dot brightness based on ever-changing ambient light conditions. Operates with a single CR2032 3v battery. With ADE’s advanced technology, the sight only draws very minimum power to give a very long battery life. The brightness will turn high and low according to the environment's brightness.
