ADE RD3-012PRO Motion Awake (Sensor Activated) System Red Dot with 2MOA Dot and 32 MOA Circle Multi Reticle Reflex Sight for Handgun That is Compatible with Doctor Footprint – Compact Reflex Optic

Functions Perfectly – Open design allows almost instant site picture acquisition- “unlimited” eye reliefUnfortunately, or fortunately, we are living in the midst of a rapid evolution of types of “optics ready” pistol slides with a plethora of proprietary mounting systems. You must be careful that you match your “FOOTPRINT TYPE”. The website description is very thorough and carefully explains the necessary type of mounting system. Quoting verbatim, “Comes with Red dot, tool, removeable[sic] picatinny plate with two screws, cover, lens cloth and instruction manual. Fits pistol optic plate/cut that is compatible with Doctor/Vortex Venom/Burris Fastfire footprint. Does NOT fit optic plate/cut for RMR, Shield RMS type footprints..”As for me, I will be using the attached Picatinny mounting clamp to attach to the Picatinny Rail attached to my firearm.The manufacturer has high Quality Control standards because the parts were flawless. The windage and elevation adjustments operate smoothly and stay put. The mechanical and optical engineers were really thinking and they designed a great sight. I really like the very useful automatic off and “motion activated” feature. I also choose this “Red Dot” for the double “Red Dot” of a 2 MOA size centered Red Dot within a 32 MOA sized outer circle.I have a severe eye vision problem called “an astigmatism”. My Cornea is distorted and that distortion distorts point images and makes the point image appear as a smear. I did not understand this phenomenon when I got my first tube enclosed Red Dot scope. To me the Red Dot appeared as an hourglass instead of the perfectly round Red Dot it should have been. So, I sent the “defective” Red Dot Scope back and got a replacement. Only to see the same hourglass shape, instead of the perfectly round Red Dot, on the replacement scope. I showed the Red Dot Scope to a more knowledgeable friend of mine and he told me that he saw a perfectly round Red Dot and he explained my eyesight problem and off I went to the eye doctor. It turns out that special contacts can somewhat correct my eye vision problem.I showed this OPEN RED Dot sight to my friend, who has good vision, and he said that the image is perfectly sharp. So, if you think that this OPEN RED Dot scope has a lower quality image, then you need to have your eyes examined and your vision corrected as much as possible. There is a special contact lens that really fixes your astigmatism so that you can see better without as much distortion.
