Features

  • NOTICE: Astigmatism can cause a red dot reticle to look blurry/fuzzy/have a tail/duplicate dots/etc. This is a VERY common eye condition many have but are unaware of. A quick at home check is to take a picture of the reticle with your phones camera as your phone cannot have an astigmatism.
  • NOTICE 2: Another issue can be from having the brightness setting up too high in a bad lighting environment like being indoors. Try turning the brightness down and repeating the previous suggestion if the reticle is still blurry to your eyes. If the reticle is still blurry in both pictures, there may be an issue with the reticle that is covered.
  • Green-Illuminated ACSS Vulcan Dot Reticle System
  • Ultra-compact size for concealed carry applications
  • Two Reticle Settings: Chevron + Circle, and Chevron only

  • The best micro dot that exists for micro edc handguns
Best optic currently available for everyday carry micro compact handguns. On these tiny window optics it can be nearly impossible to “find the dot” when presenting the firearm, especially under stress. This baby has the dashed 230 MOA outer ring to help drive you right on target to the center 3 MOA dot, without even having to think about it. Its use is naturally intuitive and could literally save your life. Even pros like it for when shooting from weird positions such laying down or one handed behind cover sideways. Only thing better would be a fully enclosed emitter model, but no such beast exists as of this review. They haven't yet figured out how to package an enclosed emitter in such a micro optic. This thing is so tiny, but I absolutely love it more than any other optic I own, which are many. ... show more

  • My go to optic.
I have two of these. On a subcompact handgun they are great. The ACSS Vulcan Reticle makes is much easier to get on target quickly. Several of my friends have tried it and they all say it's their favorite too. Holosun's side battery trey is so much more convenient than some of my other micro dots that require me to remove the optic to change the battery, making it necessary to rezero. They also make an ACSS reticle for the 507C and it is just as impressive. ... show more

  • Worth every bit of the money!
This dot is really fast to locate! I will be putting this on all my pistols. Only problem I had is from the 3 sets of screws they sent they did not include any M4 screws which is what my gun needed. I would highly recommend this site.

  • Holosun 507K with Vulcan Targeting System
Direct fit to S&W Equalizer - super clear green dot that is great for those just getting into green/red dot sights - will absolutely buy again

  • Good optic but expected a chevron
This is my second optic from the company . This is the first with the Vulcan reticle . I was expecting a chevron not a 3moa dot, but other than that everything works great . I’d rather have had a 6 moa or even a 3 with a 30 as an option along with the outside 232 for aiming
