Great optic combo, highly recommend
I may be biased in that I already have several Holosun optics and wanted this for a rifle since I am familiar with them already. This is a great optic, with quick connect/disconnect (just flip a lever that is adjustable for tension and it comes off), both for the optic and for the magnifier. That was important since I do a lot of close shooting (less than 25 yards), so I wanted to be able to take the magnifier off and put it on easily. Also, I have a low mount picatinny rail that they are mounted on so I can’t co-witness with the iron sights with the optic on, but if it ever fails it is so easily removed that it’s not really an issue. Easy to mount, easy to zero and easy to use. I like having the option of either dot with circle (close) or just dot (farther away or for better accuracy) as well as adjustable brightness. The only negative is that the buttons on the side to adjust brightness and circle/dot are not that easy to feel in order to use when trying to look through the optic.

Worthy optic system
I love this setup. Easy to install and use. Eye relief is nice along with the field of view. Definitely worth the money.

Amazing Optic!!
This in an incredibly high quality product. Holosun has made a name for themselves in the bang for buck optic space, and this is a perfect example. Eye relief on magnifier is top notch, and adjustability is nice. Mechanism for flip to side magnifier works incredibly. Had it for over a year now and no worries about the battery. Easy QD mounting system makes it perfect for moving it from rifle to rifle as needed. Can completely recommend this.

Red dot and scope very good combo
Very good product. Used at the range on an AR rifle. Easy to dial in. I would recommend this to anyone. If you are looking at similar types of red dots there are plenty out there and 1 in particular that is way more expensive but still very good. My opinion if this is for the range or even competition shooting you cannot go wrong with this setup.

Holosun 510c combo
The Holosun 510C and HM3X combo is a solid setup if you want speed up close and the option to reach out a bit farther. The 510C’s circle-dot reticle is quick to pick up and works great for close-quarters shooting, while the HM3X flips in easily when you want 3x magnification for mid-range shots. Build quality feels tough and dependable, and the glass is clear for the price. Battery life on the 510C is excellent thanks to the solar assist and shake-awake feature, so you’re not constantly worrying about it dying. The magnifier is smooth, holds zero well, and adds versatility without being a hassle. Overall, this combo offers great value, good performance, and flexibility for range use or a defensive rifle. It’s not the lightest setup out there, but for the money, it’s hard to beat

Legitimate Holosun
Legitimate Holosun. Everything was included and was in new condition. Some people left reviews saying that they received an optics with markings on it. I did as well, but they wiped right off. It seemed to just be the powder from single-use vinyl gloves. There is marking on the magnifier, but that is just where the metal rubs when flipping it. Super happy with this purchase.
