## Description

The HE403C-GR is a 20mm micro optical sight designed for equipment and carbine applications. Features include 12 brightness settings, the Green Super LED with up to 50,000 hour battery life, and 2 MOA Dot. Tech & Features include Solar Failsafe, Shake Awake, Super LED, and Multilayer Reflective Glass. Solar Failsafe allows the red dot sight to remain powered when your battery fails. This features automatic brightness adjustment; when you’re under the sun you have a bright reticle, when you move indoors it will automatically dim down to match ambient lighting conditions. Shake Awake Technology shuts the LED off during periods of motionlessness. The amount of time it takes for the LED to deactivate (enter Sleep Mode) is user programmable. Shake Awake can also be completely deactivated which keeps the optic powered on for up to 100k hours (certain models). The Super LEDs provide a versatile range of intensity for the brightest environments down to no-light situations. High luminous efficiency, the human eye is more sensitive and comfortable to gold and green (high visual function). Not only does the Super Green LED give the user an option for those who have difficulty seeing in the red color spectrum, but it also gives greater power efficiency when using the optic in high brightness settings. The Multilayers Coatings include red dot sights and magnifiers are manufactured using optical glass with multilayer coatings applied to facilitate maximum light transmission and wear resistance while reducing glare. Additional features also include 2 MOA Green Dot Reticle, 12 bright settings, convenience tray battery compartment, parallax free and eye relief. In the box: HE403C-GR 20mm micro optical Green dot sight, Battery CR2032, Lower 1/3 Cowitness Mount, Low Profile Mount, T10 L Key, Rubber Cover, User Manual, CR2032 Battery, and Lens Cloth.

Review: Great pick. Worth it and more - Got this at a great price. Out of the box the sight was on and was visible without a battery. Vary impressed. Mounted on my ar15 and it looks great. It's a 1/3 Co witness and easy to shoot through with iron sights. I had a concern at from the start because the battery compartment wasn't like the picture. It was a slip on battery holder unlike the picture with the 2 screws. But after contacting the company they said its the newer model, and it is still water proof as advertised. Wile I was messing with it I noticed that there are 3 settings on solar power. It will auto adjusts so the ambient light and pick a setting. On manual it will go from barley visible to a giant red dot that is easy to pick up. Looking into the dot it's not a perfect circle, more like a real small line but not as noticeable unless your really looking for it. After I Co witnessed it I went to the range and it held zero great, shot out to 400 yard with out a problem. 5 months later and about 700 round , it's still kicking vary impressed and will keep testing it and updating as time goes on. The only con I have is that it won't take normal t-1 risers but the one it came with is solid
Review: A great reflex sight by a well known company - This sight is everything a reflex sight should be. Where the brightness automatically adjusts to the light is honestly incredible. The shake awake is also a life saver. To have the confidence that the sight just turns on with out having to fumble with a button is just perfect. Why doesn’t all good named companies use this option on all their sights. And the cost is honestly to low for the value of the sight. Now it is a little different when setting zero. It is not near as touchy as other sights. You can get frustrated when adjusting the sight. You will have to be more generous in the adjustments. All in all I will recommend this sight to anyone. Also it is just a 2 MOA DOT. That is all I wanted. I didn’t want the options for different reticles. That is just me.

### ⭐⭐⭐⭐⭐ Great red dot with clear detail and easy to use.
*by K***Y on April 18, 2018*

Really enjoy this on my Springfield saint pistol. This is running on a short barrel .223 pistol and it performs very well. Easy to adjust with the built in turn caps to dial it in and the always on feature and auto off are a no brainer to reserve power. In addition the anticipated battery life is stellar and looking forward to getting many hours out of this unit. The dot is clear and crisp which makes targeting and keeping a tight group easier but the ability to crank up the brightness is nice in case of a bright day to still clearly see the dot in any environment is great. So far no functionality issues and mounting seems rock solid. I would definitely tell a friend to have no reservations in buying this compared to the over priced aimpoint scopes. This hasn't been tested over the long haul but it seems to be of solid construction. Great piece of hardware and if I have a similar gun philosophy I will likely put this same scope on that gun as well.
