HOUSTON, TEXAS – The U.S. Patent and Trademark Office has issued a Utility Patent to the ACSS® Vulcan® reticle system, featured exclusively in Primary Arms Optics’ co-branded Holosun HS507C-X2 ACSS mini reflex sight.
The patent (US 11,150,052 B2) was granted to ACSS’s creator, Dimitri Mikroulis, who maintains long-term collaboration and exclusivity with Primary Arms Optics.

Unlike traditional reflex reticles, the ACSS Vulcan features a combined center aiming chevron and a large outer circle. When looking through the sight at arm’s length, this circle falls outside the optic window. However, if the optic is off-center, the circle will show the error and guide the user back to proper alignment. The utility patent grants protection for the reticle’s unique visual correction system, wherein at an operable eye distance of the optical sight, when the one or more aiming marks are in a field of view of the optical sight the one or more non-aiming marks are outside the field of view of the optical sight.
This feature is invaluable in high-movement, dynamic shooting applications, where the user might engage a target from an irregular shooting position, such as inverted kneeling, rollover prone, or weak-side one-handed. For this reason, professional users will recognize the design’s advantages in high-stress defensive shooting scenarios. This design is also highly beneficial under night vision, where focal settings and device length can limit the visibility and acquisition speed of traditional reflex reticles. Under night vision, the ACSS Vulcan reticle provides an intuitive ‘heads up’ style reticle view, making it easy to acquire and maintain on target.
“The design and technology behind the ACSS Vulcan reticle set it apart from anything else on the market,” says Stephen Morgan, Director of Product Marketing at Primary Arms Optics. “This utility patent reflects the ingenuity put into this unique aiming system, which addresses some of the most challenging problems associated with mini reflex sights.”
