About this item

    This fits your .
  • Make sure this fits by entering your model number.
  • SOLAR FAILSAFE: Holosun's Solar Power Failsafe Technology allows the red dot sight to remain reliably powered if your battery ever fails in a critical situation. The battery life can last up to 50,000 hours depending on settings.
  • AUTOMATIC BRIGHTNESS ADJUSTMENT: With the Solar Failsafe feature, the reticle will automatically become bright if you are under the sun, and will automatically dim down when you move indoors to match ambient lighting conditions.
  • SHAKE AWAKE: With Holosun's Shake Awake Technology, the slightest movement will trigger the on-board motion sensor to instantly activate the LED. During periods of motionlessness, the LED will turn off to save critical battery life.
  • MULTI-RETICLE SYSTEM: With this feature, you can turn toggle sections of the reticle based on the job at hand and preferred vision. Select between the precision of a 2 MOA dot, a 65 MOA open circle, or a fast acquisition circle-dot reticle.
  • MULTI-LAYER COATINGS: Holosun optics are manufactured using optical glass with multi-layer coatings applied to facilitate maximum light transmission and wear resistance while reducing glare, making for a great addition to your tactical gear.

5.0 out of 5 stars Beats RMR and Vortex dots. Best value red dot out there.
By Marco Chavanne on March 23, 2019
I've had an RMR and a few Vorted red dots. The RMR had the dimming issue I resolved with an antiflicker plate and I loved it. The Vortex dots aren't sexy but they just work. I could punch a penny at 25 yards with both.

This new Holosun however beats them all. The features, construction, and options put it above the competition at almost half the price.

Perfect cowitness with the BUIS that came with my B&T GHM9. Took a considerable amount of left to right adjustment, but the up down was dead on.

The shake to wake feature gives it true "Go Gun" status. No fiddling with buttons to turn it on. In a bad situation you don't want to have to try to turn one on when you really need it. Pulling it out of your bag will bring it to life and you're ready to rock.

Autodimming is also a great feature my RMR and Vortex dots didn't have. Once enabled you will see a noticeable and immediate difference going from dark/dim to brighter areas. Works excellent outside. The feature is disabled by holding the + button for 3 seconds. This would be ideal if you're in a shaded environment and your target is outside in a brightly illuminated area.

In the higher brightness settings you can still see the reticle when you point it towards the sun. You won't lose your dot in bright areas.

The reticle options are also very hand. 2moa dot will help you plink pretty far down range and the larger 65moa reticle will give you fast acquisition at closer range. They defiently both have their place. And neither the RMR or Vortex dots offered multiple options.

The battery life is supposed to be incredible. I haven't had it long to know, but all testing has shown you'll have years between battery changes. Keep in mind it does come with a spare battery tray so you if your grip has storage you can keep the included torx tool and spare battery with you when it becomes an issue.

The solar feature is reassuring. Worst case scenario youre in the field or fight and the battery dies. If you are outside in the sun, or have enough ambient light the dot will still work. If SHTF and batteries are no longer available, you'll still be able to use it.

The value, man.. It is just a no brainer. Half the price of an MRO or RMR. More features. More rugged design. The Alamaba Arsenal torture test includes, pouring water on it, throwing it 20ft into the air and letting it hit the ground, freezing it in ice, beating on it, and SHOOTING it with a shotgun, and it still held zero.

The quick release mount also saves you an extra $150 if you were running other dots and allows for a perfect BUIS cowitness. Mine fit a little loose when I first installed it. I used the included tool and tightened the mount one turn and it clamped down with the force of an Amazonians thighs during Snoo Snoo. Absolutely solid now and still easy to release with the convenient latch keeper.

The picture is incredible. The thinner profile sides and large viewing window give a natural feel and you're not chasing the dot around. No toilet paper tube EFFECT or black glob in the corner like with the Vortex Sparc AR. With boys eyes open you hardly notice the frame. You just see everything as well as a dot in your FOV.

I will probably buy another one for my next Scorpion build. Can't imagine anyone coming out with a better optic for the money.

5.0 out of 5 stars Best affordable reflex sight on the market.
By Alexf on March 6, 2017
I'll start out with the only negative and a disclaimer. The first optic I received from this seller was defective. It wouldn't project under normal daylight without the battery and would only work in direct sunlight. On top of that, there was excess glue, markings in the finish, and worst of all, you could see the square LED housing outline reflect off the glass which was very distracting.

With that said, these guys have the best customer service I've ever seen from any company I've ever had to deal with. I emailed them with detailed pictures of my issues, and less than 4 hours later they sent me a tracking number for the new optic. I received the new optic 3 days later with a return label for the old one.

The new optic is flawless. It is the best reflex sight I've ever seen, at any price point. Reticle is the sharpest I've ever seen on a reflex sight, gets plenty bright and I get zero parallax. This, coupled with excellent customer service make it one of the best purchases I've ever made. I'm really glad I went with this optic over the eotech i was looking at. It is honestly better than the eotech, and is half the price.
This is also one of the most technologically advanced reflex sights out there. The auto on feature has worked every time for me so far. It is sensitive enough to pick up you dropping the included torx tool on the table next to it. Sight will work without the battery provided there is any ambient lighting at all. You do not have to be outside or in direct sunlight. Auto brightness is a bit too dim for my liking, but it does work very well and adjusts instantaneously. I just wish it would be about 10% brighter in all conditions.

The only sight I've ever liked more, is the trijicon ACOG, but obviously that's apples to oranges. I would highly recommend picking this up.
Just for reference, if any of you are considering picking this up for a scorpion EVO, I think it fits it really well. I would probably go with a smaller optic if you're planning on keeping it a pistol, but if you're going to go with SBR route, it's perfect.
(I've added a photo of this optic mounted on the EVO)
