## Description

The HS510C Open Reflex Circle Dot Sight has an open frame for a wide sight picture. It is powered by solar cell under normal usage, and a back-up battery to supplement power requirements in low light conditions. The reticle can be switched between a 65 MOA circle with 2 MOA dot, a 2 MOA dot only, or a 65 MOA ring only at the push of a button. Better yet, the same LED projects both reticles, so no re-zeroing is necessary.

Review: Outstanding magnifier...Super good value - Outstanding product loved the magnifier, put it on my ar-15 and used with my strike eagle 2 red dot and works flawlessly...easy to install..comes in very nice case, with everything you need mount it it on the rail. I was shooting 3 inch groups at 100 yards. Outstanding price...very clear lenses. Well worth money

Excellent sight picture ,very clear and durable optic, I shoot a lot and I believe this is my eighth one I have purchased for the collection of rifles I have, I own EOTECH and many others, there is nothing more durable than EOTECH but this comes pretty close when you look at it has solar so you really never worry about it working, shake awake, fog and water proof, night vision capabilities, reliable to zero every time, don’t worry about the battery and don’t forget to buy a cheap cover to go with it, you really can’t go wrong with any of the Holosun line

## Questions & Answers

**Q: Will this fit on a Glock 19?**
A: Get a Holosun 507c instead. The 510c is meant for rifles. I personally have a 507c v2 on my glock 17. Fits Trijicon RMR footprint too.

**Q: What is the country of origin?**
A: China, honestly nowadays it doesnt matter,  china is starting to make affordable well made products.  Americans workers are getting lazy and entitled,  most is the same or worst quality then china

**Q: So if the battery needs to charge for this you just leave optic in the sun for a recharge?**
A: Way it was explained to me is, the solar panel charges a capacitor on the inside. It won't be as bright, but it is a failsafe and can confirm it does work. It's truly an end of the world optic and that statement is coming from a guy who wanted to hate it.

**Q: How many reticles does this have on it to choose from?**
A: It has 3... 65 moa outer with 2 moa inner, 2 moa inner only or 65 moa outer only

### ⭐⭐⭐⭐⭐ Top notch Optic
*by C***T on October 26, 2024*

I have owned this little optic for about a year now. First on a rifle but now resides in my home defense shotgun. I have found this to be a tough well made optic that holds zero even through punishing recoil of a shotgun. I have had zero issues with the QD mount attaching to the picc rail of my firearm and once there it is rock solid. The reticle is crisp and clear even with aging eyes. The adjustments in illumination level is easy and is palpably visible. There is some blurring on the highest level, but this in no way makes the optic unusable at this level. The sighting adjustments are a little mushy, but you can feel each click. I was able to Ranger Wrap my 510c to match my A 300 and that was like icing on the cake for this tough little guy. One drawback is that it has an open emitter that could become dirty or occluded. After several range trips in dry dusty conditions, I have yet to experience a failure in function. This optic is a solid addition that you can depend on plus your wife won't kick you out after purchasing it!!
