Construction
The RD3-018S Red Dot Sight is made of hard-coated aircraft aluminum and multi-coated glass. The sight does not have a plastic body with a polymer lens. Ade SPIKE created an iron sight curve at the end of the body and also added two white dots on the curve for the rear of part of the red dot to become a backup iron sight. With the ultra-short design, the red dot provides a distance/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 Spike's rear white dot will act as a pistol factory original rear sight for Co-Witness.
Operating Mechanism
The ADE SPIKE red dot sight is always powered on with automatic brightness. It operates with a single CR2032 3v battery. With advanced technology, the sight only draws approximately 700-microampere power to give a very long battery life. The brightness will turn high and low accordingly to the environment's brightness. 
Ready to Use
It comes with screws for several Optics Ready handguns but does not come with any mounting plate such as a Picatinny mount or plate made for a specific handgun. It comes with 3 pairs of screws for Sig P365XL/X, Springfield Hellcat OSP, and Canik TP9 Elite SC ONLY. The provided screws might not work with every compatible pistol listed. ADE makes the red dot accept the industrial standard footprint. The pistol manufacturer makes the optic cut/slide for the same footprint, but they have their own opinions to decide which type screws the screw holes take. Since ADE does not know the screw spec every pistol manufacturer used for their screw hole, please ask the pistol manufacturer what screw specs they used on the hole and ask them to provide the screw. If you can’t get the screw to work properly, it is recommended to visit a local hardware store such as ACE Hardware to get the right size.
