Holosun HE507C-GR-X2 Pistol Green Dot Sight - ACSS® Vulcan™ Reticle

I’ve purchased two of theses optic & they’re TRUE to their hype. Only down fall is that the ACSS reticle is not etched on the optics glass like on the Primary Arms RIFLE optics with the ACSS reticle. That fact caught me by surprise when I received my first Primary Arms 507 c GR-2X . But I still purchased a second one. Because I know how to use fixed sights in the event the optic malfunctions. Hopefully in the future they will etch the ACSS on all their advertised ACSS reticle optics.Respectfully Yours Retired NYCD/ESU Officer Anthony U.

I bought a holosun 507c Vulcan green dot optic and I damaged it due to my stupidity. I was very upset with myself. I contacted primary arms and asked if they could look at it and tell me if it could possibly be repaired. They sent me a brand new one. I was so thankful for what they did that I called and personally thanked them. They are a fantastic store.

This is the only type of pistol sight I will ever use! The ACSS Vulcan’s ability to obtain your “dot” within milliseconds from any position is hard to explain to someone who has never used this type of sight. Every time I let someone try it I have trouble getting my pistol back. Everyone falls in love with the concept and they also don’t want to shoot with anything else! Great job Primary Arms! You are going to change the red dot industry forever.

I had 5 people look through this optic, in different lighting conditions, different power settings, and all of us saw multiple legs on the bottom of of the chevron. Sent it back, RMA. Still waiting on the replacement to show up. I hope the next one is crisp like it is advertised.

We are glad we were able to get you taken care of with an exchanged optic. Please do not hesitate to reach out if you have any questions.

This is my second Holosun so far. I’m loving this optic on my Shadow Systems MR920 Elite! My other is a 507K, also in green, mounted on a G43X MOS. I much prefer the green over the red dots as they are much easier for me to pick up. My 15 year old and I both love shooting these two optics.

My ONLY complaint: it did not come with the full instructions. I was having a hard time zeroing it because it was way too bright and I could not dim it. The instructions to turn off the auto dimming are included on the page of instructions I did not receive. After some internet research, figured it out. Now she’s running beautifully!

I will definitely buy another 507K in green for the War Poet CR920 on order. Holosun makes a great optic as a good price.

This optic is great. I owne one on every pistol that can take a dot. I belive its perfect for a CCW because you can easily find the dot in a stressful situation. My only reason for a 4/5 is the fact mine came with a dead battery. I had to go to 8 different stores to track one down and finaly ended up finding one at a small car shop. This isn't really on Primary Arms but still a huge pain in the butt.

Easy to install. Really like the ACSS reticle since this is my first pistol sight and I was worried about not being able to locate the chevron quickly. The ACSS large circle makes it easy. I was surprised with my accuracy at 50 yards mounted on a PSA Glock clone.

Item as advertised. Great product from Holosun.

I have 6 of these now. Very versatile.
1301 Shotgun on CROM,Piggybacked on an ACOG for AR, handguns. The big ring is nice for awkward positions like broke back prone but is otherwise out of the way and decluttered. Chevron tip for precise and give a dunce-cap for POI shift up close. Also nice for extended ranges to have a reference point vs. single dot.

This is my first Holosun RMR as I have been a faithful Trijicon RMR fan for years. Been seeing alot of positive reviews on Holosun and thought I would give them a try. I found this model and everyone raved about the ACSS Vulcan reticle. Well I am now a believer, very well made, excellent glass and the reticle is fantastic. The green arrow reticle is sharp and intuitive without the flare of a red or green dot. I liked it so much I just ordered a Holosun 507K-Gr-X2 ACSS Vulcan site for my S&W M&P 5.7.
