Primary Arms/Holosun 509 ACSS Vulcan Review
This review highlights the Primary Arms 509 with the ACSS Vulcan reticle as a top-tier optic for duty or concealed carry. Key benefits include its closed emitter design, 20,000-hour battery life with solar backup, and a durable build tested in harsh conditions. The ACSS Vulcan reticle, featuring a chevron and large circle, is praised for its effectiveness in target acquisition and ranging, despite initial concerns about clutter.
