Frequently asked questions
The Shake Awake feature of the Holosun Reflex Sight is designed for power conservation. If the unit has not moved for a certain period, this feature will put the sight into sleep mode. Once it senses motion, it immediately powers back up and is ready for use.
The 2 MOA (minutes of angle) dot in Holosun Reflex Sight is the spot size at 100 yards, meaning it covers 2 inches at that distance. On the other hand, the 32 MOA circle provides a larger field of view which can be beneficial during rapid target acquisition situations.
The difference between the red and green dot in the Holosun Reflex Sight is primarily a matter of personal preference. Some individuals find the green dot to be more visible in daylight. However, performance wise, both colours provide the same functionality.
Parallax-Free means that the dot in the Holosun Reflex Sight stays in alignment with the firearm, irrespective of the shooter's eye position. This provides a significant advantage in rapid target acquisition and shooting accuracy, especially in high-stress situations.

So far I love the sight and it seems to be a great RDS which I wanted for hunting season for hogs and for under 350$ it’s a good deal. I went to my local gunsmith and looked at their stuff and asked for suggestions and this is what I ended up buying and it seems to hold zero pretty well. It took 2 adjustments to get it in the center of the paper and holding a decent group. It is as wide as my pistol so it looks as it should on my 10mm. The glass is super clear on it and even with astigmatism I found it easy to acquisition to the RDS because on my S&W M&P 2.0 I can co-witness the iron sights for 2 different ranges. I love the auto brightness but that’s just me, I seen some complain about it but I actually found it to be the right brightness for me like that vs always hunting for the “right” brightness for the ambient light. I actually used it inside and outside my home and it works well in artificial light for me but better in real sunlight of course. All in all I would buy from the seller that I did and found the sight to be in new condition even though the box was not sealed in plastic. Also the screws were in the same type of bag that the one guy is complaining about and saying it’s not factory when it obviously is (at some point the changed the bags they use). 5/5 stars for sure! Won’t be my last Holosun!

Great tool. Have ordered multiple after using the first one. Like the solar charger as well as it coming on when you draw or move the firearm. Have it on 2 sig p320 x5 legion and will be adding to a new echelon. Did not need a plate or adapter to install on the sign, so that was a definite plus. We like the green version and that there are multiple options on the reticle/dot configuration.

I remember when rds cost a month's paycheck. Bought this thinking it might be cheap. I think it's pretty good quality and has great features. I have two critiques One is the drain ports. If this is holstered on the hip as open/ duty carry, and if it rains, it will retain a small amount of water on the sight glass until its drawn. I just think the drains need moved. Two is the auto setting light sensor is on top. The auto setting is really great and reacts fast, it's excellent for bright daylight to low light conditions. It absolutely must be default when carrying. However if you have a pistol mounted flashlight and use the flashlight in the dark, the light sensor on the sight will not sense the light and will not brighten the reticle, making it impossible to see the reticle in very dark conditions. My remedy is to simply move my thumb up from my grip and press the plus button for 3 seconds changing from auto mode to manual mode. It reverts to the same brightness level it was previously set on. I'm very happy with it and have it zeroed at 100 yards on a .40 cal glock and consistently hit 8 inch steel. It came pre zeroed at 25 yards making it easy to get on paper with the first shot and adjust.

I have carried this red dot with me on my G19 for well over a year now and it has held Zero very well. It has been dropped mutable times and keeps going. Great price for a RMR red dot. The glass is clear enugh to hit steel at 75 yards. The automatic shake awake works well never had to switch batteries! I recommend!

I purchased this to replace a Vortex Defender ST that has MAJOR design and hardware flaws. Do yourself a favor and spend the extra $40 bucks and avoid the headache and hassle. The 507c/407c series of optics just work, the buttons are easy to access and manipulate, but not easy enough to inadvertently access and change your brightness/settings like the Vortex. Smaller battery but double the battery life, if you can explain that one to me, more power to you. Holosun just makes a better optic. YMMV but for me, this does the job and does it well. Also, if you're on the fence about forking out the extra coin for the 507c with the "donut of d*ath" reticle over the dot on the 407c, consider this... 1 moa is roughly the equivalent of 1 inch at 100 yards, so a 32 moa ring becomes a 32 inch circle, a 2 moa dot is 2 inches, and so on and so forth... But what about at 10 yards, 1/10 the distance? That 32 inch circle becomes a 3.2 inch circle, and that 2 inch dot becomes 1/5 of an inch. It's not going to make you a better shot by any means if your fundamentals suck and you don't practice, but when the adrenaline hits that ring is going to help you focus on that dot and make the hits count when it matters. Hope this helps. Also, side note, Holosun introduced a rolling change to their battery trays, the screws are now captured and "rachet", scared the living daylights out of me at first because I thought I stripped the screw but then I noticed that there's a ring around the screw for the battery tray now and after a little internet investigating, found out why.

Sadly I had to return this sight because of the small buttons, otherwise it's as advertised except for the ease of adjustment, those with smaller hands or more dexterity I'm sure will be pleased as the function, build quality and brightness are really nice.
