Excellent Quality Not
After 3 months and only having 20 sight in rounds shot with it, the LED is failing. I thought it was the solar cell but after a weekand 4 new different batteries, I need to turn on the dot to max brightness to be useful. I've called Holosun numerous times leaving voicemails. I regret not buying the Primary Arms MD-ADS. Don't go Holosun, they're not willing to back their products. If they were, I wouldn't be writing a complaint. Nor wasting phone minutes calling and calling...
5 Star Red Dot Sight!
by Morgan Watts
Amazing product, I am so happy with my purchase. Dot sight is perfectly waterproof, I have tested it several times and it does not fog. Very durable finish, very crisp, 2 MOA dot. Easy to dial in and zero. Solar feature works like a charm! I never use battery power when I am outside, or even when I am inside a lot of the time. I would recommend this to anyone looking to put an aimpoint style optic on their rifle.ONE THING TO NOTE. If you want to cowitness your ironsights, I bought the american defense lower 1/3 cowitness quick detach mount... Awesome mount, but it is too high for me to see my irons at all through it. I am running Magpul MBUS pros on my rifle. I would recommend the absolute cowitness american defense mount.
Best purchase! Love this red dot

Bought for the light weight, long battery life, and ease of use. Couldn't be happier with the results. It can be a little hard to initially pick up the dot depending on the background but can easily be changed if needed. Look forward to seeing the circle dot on the 503 as it may be even better.

Holosun red dot

I have a PA reddot on my Buckmark...fantastic. I would have gotten the next gen but the Solar Power interested me. Pretty neat bit of kit. It's currently on my 5.45 AR and is working perfectly. FYI it comes with two different risers
I have always wanted a red dot sight that could operate without batteries but they were always out of my price range. But now I have it. This sight is well crafted and the dot is clear. It started working without the battery upon removing it from the box. The dot was visible in my house midday with only the light coming in through the window. It will even work outside in the shade.
Probably better than my old vortex sparc..
I have yet to drop it, banged around to see how it holds up. The glass is clear and the dot is crisp as stated. So far I really like it.
unique setup not available anywhere else.

I really like this red dot. Its awesome that the dot will adjust brightness based upon the ambient light. And when it gets dark it just switches to battery, seamlessly. Its nearly perfect.

Initially a nice sight but the solar option seems to be funny. It says when not enough ambient light is auto switches to battery mode. Mine did not had to do it manually. Tried contacting Holosun but no reply back. Works fine on battery mode but thats why i bought the solar.
