Holosun 507K X2 Red Dot ACSS Vulcan Reticle, K Series Footprint (Modified RMSc) - HS507K-X2-ACSS

This optic helps me get on target faster than any other red dot I own. I wish it came in more of their optics.

Great product. Easy to mount on my Sig 9mm

I really love this red. Dot with ACSS It was becoming harder to find the red dot The new ACSS ring is awesome. I’m going to be buying two more shortly soon as I find some time. Definitely pick one up shake awake feature the battery will last way longer than you want to great purchase great place to buy from.

Work great, perfect service A+++++

Have only owned this for a week now, but so far it's great. Very easy to install and sight in. The Vulcan ACSS reticle is great. I'm embarassed to admit that I have taken an all-day class on using a pistol read dot, read an entire book on using a pistol red dot, and did literally hundreds of hours of drills attempting to learn how to make the dot appear in the window from the draw, but could only do so maybe a third of the time. This reticle makes it happen every time, PERIOD. BTW, before buying this Holosun, I had bought only American-made red dots. I feel a little bad having bought this Made in PRC product, but if they had made a reticle like this, they'd have kept 100% of my business.

I love my new optic,the delivery was prompt packaging was done with care and great product packaging as well I just sent out to get zero in professionally

A simple but ingenious solution to finding the dot. Holosun quality is excellent too. I'm very pleased with my purchase.

Great Red Dot for my FN Reflex, looks and works great

Great red dot for a great price

The ACSS is a great tool to help you acquire your target faster.

This is my second 507k with acss Vulcan reticle. I love this red dot. Using the big outer ring will greatly help training and finding your dot during the learning process when it can be harder to get that dot where you want it. After you’re learning curve it’s still useful when shooting from non conventional angles and improvised grips. All my Holosun have terrific battery life and have been dependable. Freedom Gorilla shipping is spot on, fast and efficient.

Great experience as always. No issues mounting the red dot . Freedman Gorilla is top notch

Freedom Gorilla is a company you can count on to come thru for the customer. They sell top quality equipment like the Holosun optics and back that up with support of the products. I recently had an issue with a Holosun optic I purchased when I contacted Holosun about the issue they blamed it on the gun and would not make good on their product. Freedom Gorilla found about my issue and said they would assist me. They sent me a new optic and mounting plate. They back up products they sell and put the customer first.

I have a couple Holosun 407K optics as I did not see the need for the 507k multiple reticle. However the ACSS Vulcan looked interesting to me so I gave it a try. I like the fact that the dotted reticle is not viewable when you have your dot centered, but could be very useful under stressful situations. Would definitely buy again.

Perfect slimline fit for Staccato CS. ACSS Vulcan reticle is amazing. You can always find it, even when training in awkward, suboptimal positions. Window is small but not an issue if you are target focused.

I have this in my carry G43X and the ACSS is an amazing tool.

Very fast shipping! Good follow up! I will be a repeat customer.

Great optics and dependable service! Appreciate the shorter screws for custom fit! Second optics purchase. Will be back again!

I did not install it yet, but purchased it because i used the same product on a friends pistol

Fit my firearm perfectly and mounted in minutes. ACSS reticle is the best I’ve ever used. Would buy this product again.

Makes finding the dot easy!

So far an awesome dot. I did however have the battery screw come loose while shooting and have the screw, the battery and the door go flying at an outdoor shooting area. Spent 40 minutes trying to locate the parts. Didn’t locate all of them. Check the tightness of the battery screw better yet put some blue lock-tite on it.

Optics were great along with your service

Having the correct screw length is important and if the screws are too long they can cause malfunctions in your firearm. I just ran 100 rounds through my equalizer with he 507k using these screws and had no issues.

Service was awesome but I’m just waiting on my refund for the red sight.
