Holosun HE503CU-GR Elite Circle Green Dot Sight

The green really does make a difference as it's easier to see in both dark and light. Quality is also top notch, and there are plenty of videos out there already that show the torture tests done to Holosun products so you can trust the brand.
The circle dot is pretty good, but I feel that the 65 MOA circle takes up too much real estate in the window at the standard optic position. It probably works better with their large window optics such as the 510 or their 30mm cantilever. I personally would prefer a smaller circle. Of course, the remedy would be to move the optic closer to the eye, but you will lose the ability to accept a magnifier then.
One last small thing to note: This model that I received sits higher than normal. If you change out mounts to a QD one, let's say you use an absolute cowitness mount it will actually be a 1/3rd cowitness. If you use a 1/3rd cowitness mount, the irons will not show up at all. Keep that in mind.

I like this optic a lot! I have the sight set up so the dot and circle are both on and the green really stands out for my eyes. The circle really makes for quick acquisition on close targets. I think the shake awake feature is a great idea and works well. So far I have used it in a couple 3 gun matches and some static range use for about 700-800 rounds. Certainly not a high round count but then most of my guns are not getting high round counts these days!

Awesome red dot, love it, everything you'll need in precision aiming.

This is a great optic at this price. Full confidence in its durability, feature packed...insane battery life... seemingly always on..Great reticles. i wont be purchasing any Aimpoints or Trijicons until they start offering the features Holosun offers at a 1/4 of the thier prices

Great Company, good service. They do what they say they will do! The Holosun HE503CU-GR Elite is what I expected. Very little adjustment needed right out of the box. I use Holosun on everything I can. Good products at a good price point.

When I need a scope, red dot, or any other kind of visual enhancement for these old eyes, I come to Primary Arms and I look at their proprietary brand as well as Holosun. Sometimes, I even find a joint venture between the two. Never been disappointed by any purchase or quality of products from PA!

I'm 76 years old and my eyes don't focus as well as they used to. Open sights are now so blurry that I can't use them and scopes seem so heavy. At the range, a friend let me try his Holosun green dot and I was hooked. What a difference! I really enjoy this optic and the long battery life with solar back up gives me confidence when I go hunting. The HE503CU-GR has many great features and I highly recommend it!
