Holosun SCS MOS Green Dot Sight for GLOCK MOS Cut

The one I purchased was for full size Glock, mines is sub compact so it didn’t fit. I sent it back and awaiting refund.

Purchased new Halosun SCS from PA. Charged it right out of box in daylight for many hours. Green dot would not switch on. Sight is inoperative. I Tried to initiate return using Holosun website. That product registration electronic tool was also inoperative. I have a very expensive paperweight now and a very negative customer experience. There are better sight options out there.

I purchased this to mount on a Gen 5, G19 MOS. The install and zeroing were simple. I torqued to spec and now have run over 500 rounds without a shift in my witness marks. The green dot shows up well even on a green (forest) background. The auto adjust is decent, the constant bright it too bright. The dot is a starburst in most instances, but at 2MOA it is small enough to hold accuracy. I shot an agency approved Practical Pistol Course (PPC) and scored 300 out of 300 and a 50X (< 7 rounds out of the X ring and headshot box, I'm normally in the 290's with standard sights. This was totally cheating, put the dot on the target and that's where the round goes. It was like playing a video game. I will be adding more of these sites to my weapons. Other notables, it holds a charge, I left it on for over 2 weeks in my safe and it was still running bright. The build is robust but not unconcealable. Fit and finish is perfect, it looks like it was factory.

Caution: the SCS comes with weak, cheap screws from the factory. I should have checked the web, the screws usually break off on the SCS and EPS. My new SCS was mounted on a Glock 19 MOS, torqued to manufacturer specifications using a Wheeler torque wrench with blue Loctite. The screws were also witness- marked. After 300 rounds, one of the screws broke off, and no, the screws never walked off - I checked each time. It cost me $80 to remove the stuck screw. Holosun, put in better screws on these things.

Easy to mount on the Glock MOS system. It allows use of the standard height irons and is utter simplicity with one button for all operations.The auto adjust appears to work well, no flickering or hesitation when transitioning. Only time will tell how the internal battery works? 🇺🇸👮🏻‍♂️👮🏻‍♂️

The holosun scs is a great red dot sight
Easy to install and did I mention they deliver my Holosun with in 2 days to New Jersey. Will definitely shop for red dots here again

Excellent sight. Recently qualified with this sight and it was dead on. Widely trusted as a duty weapon optic, I highly recommend!

Very impressed by the auto bright adjustment and it fits my G45 MOS perfect. But.. why isn’t it a shake awake for this price. It’s literally the only Holosun I have that doesn’t have that and the tiny button to power it on is stupid tiny. PA also needs to step up their shipping game. I’m San Antonio I=10 and you’re Houston. It should not take three or more days to go less than four hours.

This site fit perfectly on my Glock 20 with no plate needed. It is low profile allowing me to co-witness which is a plus. The green dot is very clear even in daylight. I highly recommend this optic. I only wish that bit was made in the USA.

Great product and super price, perfect fit!!!
