PRODUCT DESCRIPTION
The Holosun HE509-RD is an enclosed micro red dot sight designed for shooters who demand accuracy, ruggedness, and advanced reticle technology. Outfitted with the ACSS Vulcan reticle, this optic offers unmatched speed and precision for defensive carry, duty use, or competition.
Unlike standard red dot reticles, the ACSS Vulcan features a 10 MOA center chevron and a massive 250 MOA outer reference circle. This design helps guide your eye to center, dramatically reducing the learning curve and increasing consistency in high-stress situations. The outer circle disappears when the dot is properly aligned, but appears in the periphery when your sight alignment is off, helping you get back on target fast.
The HE509-RD is fully enclosed to protect the emitter from dirt, water, and impact. Constructed from 7075-T6 aluminum and finished in matte black, the housing is waterproof and shock-resistant. Solar Failsafe technology provides power redundancy through solar charging, while Shake Awake ensures the sight activates instantly when moved. Battery life exceeds 20,000 hours on medium settings using the included CR1632 battery.
Compatible with the Holosun 507C mounting footprint, this optic fits a wide range of pistol platforms and aftermarket plates. It’s the ideal red dot for users who prioritize rapid dot acquisition, durability, and a smart, intuitive reticle.

Love this reticle
Posted by WardNow that i’ve used the acss vulcan reticle i don’t think i’ll get anything different for my pistols.
Holy grail
Posted by DeeMy double stack 1911 is finally completed after months of waiting for restock from a lot of other places i’d found my 509 acss vulcan at simmons sporting goods. I have the 507 acss vulcan and it’s a great optic for those with stigmatism. When i found ssg they had what i needed and also provided me with a coupon to sweeten the deal. Great customer support team that won future business. Thanks
Brilliant pragmatic concept in actiin
Posted by ChristopherYears ago, when a fellow student in a pistol training class showed me the acss built into his optic, i was impressed and decided to get one the next time i got a new handgun. So, when i purchased a new springfield xd-m elite 10mm handgun, i decided to go with the closed system holosun 509. W o w ! to say i'm impressed is an understatement. From the quality of the manufacturing to the well engineered design features, the performance of this optic is remarkable. Spendy? yes. Worth it? definitely. In addition, the purchasing experience through simmons sporting goods was first rate.
