## Questions & Answers

**Q: Do they send the green dot? the picture shown is the red dot. do they send the he510c gr elite or the  he510c elite**

**Q: What type of mount does it use?**
A: It comes with a QD(Quick Detach) mount.  It fits the Picatinny rail, also known as a MIL-STD-1913 rail.

**Q: The red dor can be exported for other countrys? I need some certifica-te?**
A: Let other countries come up with there own technology.

**Q: Will this fit on a Ruger 22/45 Tac-lite 22lr pistol?**
A: I don't own a 10/22 nor a 22/45 Ruger but my guess is that it will be on the big side. This sight is excellent, I've personally have it on Two AR's and they do everything a sight twice as expensive does in any gun range and or hog hunting trip. I tell ya... they work!

### ⭐⭐⭐⭐⭐ Best quality optic for the money
*by S***A on April 26, 2022*

I waited almost a year after buying this to do a long-term review. To all the haters who told me I NEED to buy a top-tier optic like an Aimpoint or an Eotech and this isn't reliable, I can honestly say this optic is very sturdy and reliable. I've ran this in several competitions now, it's been thrown around in the back of a truck, been drenched in water, and been attached to a carbine with almost a thousand rounds of recoil and it has held zero and still as reliable as day one. I can hit 1/3rd ipsc targets at 100 yards without any problems, and I'm not exactly good. Granted, I don't abuse my equipment all that much, I'm not going to be taking this thing to war or running over it with a truck just to prove a point, but for 99% of "normal" applications this thing is rock solid. I shopped around a lot before buying this, compared against other brands, I get less "star burst" with my astigmatism compared to other brands of red dots (specifically the Sig branded ones are bad for my eyes), the optic is clear and the illumination is plenty bright for bright outdoor conditions with plenty of brightness settings for any situation (fwiw, the Vortex optics IMO don't have enough brightness settings, and don't get quite bright enough for direct sunlight, but an etched reticle can fix that problem). Holosun is the real deal. I might buy another one soon.
