Holosun HS507C-X2 Pistol Red Dot Sight - ACSS® Vulcan® Reticle

So far everything works as advertised, love the chevron over the dot and very fast acquisitions.

So I've gotten 2 of these red dots, 1 was a replacement and the other was unusable. I don't know if I'm just really unlucky or the quality control over at holosun went down recently but the first red dot I got was covered it specks all over the glass. Inside it was also missing screws to mount the red dot. The current one has specks over the bottom of the circle so that isn't that major of an issue, but still speaks to the quality control over there. I really like the reticle and this is my first pistol red dot, I've owned other holosun products such as the 503g and that glass is clean and clear which lead me to think that holosun is gtg but now I'm not sure I even want to keep the 507c. I really hope that it was just bad luck because the price is very attractive, the reticle is great, and the features that it comes with are all outstanding.

From PA - The gap at the bottom of the reticle is normal and on purpose.
We are happy that we got you taken care of per our conversation and please let us know if there is anything else we may help you with.

I got to shoot the 507C-X2-ACSS on an otherwise stock CZ P-10F at 100 yards, and was impressed with the results. I'm not an amazing shot by any means, but from a rest, I was able to hit a steel silhouette with boring regularity, and about half the time while standing and shooting offhand.

I have astigmatism, and tend to see reticles that aren't simple dots with less distortion than dot-only reticles, and the ACSS Vulcan is no exception in that regard.

Took my Walther PDP to the range after receiving and installing my new Holosun ACSS Vulcan reticle device. I was simply amazed at the accuracy! I did not even have to make adjustments. If I had 500 more rounds of .9mm I am sure a click or so but extremely happy with this red dot! Save and order one to enjoy! Thanks Primary Arms

Wanted a Red Dot for my new PDP and chose this one because of all the positive news and reviews. It is my first experience with a Red Dot and I am very happy with it so far.

This is my first Holosun RDS and man, am I impressed. Really impressive build quality and the reticle, as with all things ACSS, is amazing. Mounts on the RMR footprint. Solar power is cool but even better is the automatic brightness. At first I tested this in my garage and I thought yeah, it's OK, but not daylight bright. Then I went outside in the mid-day sun...holy cow! It's daylight bright for sure! My vision is to the point with my dominant eye where red dots are starbursts but the V on the ACSS reticle is clear and sharp. I went with the red one but my next will be green to see how that works. Highly recommend.

Would like to thank PA for its great customer service. I originally ordered the Holosun (507C) when I needed the 507K. They accepted the return and promptly shipped out the new red dot!

I now own 2 of these and they are fantastic optics. I am not easy on my stuff and they hold up great. Just wish they made it in the K version and it would be on my carry gun as well.

Best (and easiest) pistol red dot I have used. ACSS chevron is easy to use & true. Until I become very good using a pistol red dot, I can’t see me buying any other (can’t see me getting that good). See you again soon Primary Arms!

Just mounted it on my CZ P01 which was pretty straight forward run 50 shots though it , Super Easy to acquire and what was unexpected for me is that the chevron is easier to use at distance as it will not cover the target fully like my other red dots like on my P365X
