The Holosun HE509 fully enclosed Red Dot Sight features Solar Failsafe™ technology that will keep your reticle illuminated should your battery ever run out. Additionally, the Shake Awake™ technology allows the reticle to shut off when not in use and instantly turn on when it senses movement further extending the battery life. The closed emitter red dot sight style ensures your optic is always working rain or shine keeping water, dirt, or debris from covering the emitter while also preventing the lens from fogging up. The housing is machined from aluminum and hardcoat anodized for durability while only weighing in at 2 ounces. Available with either a GLOCK MOS or 507c mounting adapter plate, so you can easily get it mounted to your handgun right out of the box.

Available Reticles

ACSS Vulcan – Chevron

The revolutionary patented ACSS Vulcan reticle provides a large circle guiding the eyes towards the 10 MOA center chevron, eliminating one of the biggest challenges for shooters new to slide-mounted red dots. If you are off-center, a portion of this outer circle will appear in the window to give you an instant reference on how to get centered. The circle phases out of the sight window completely when the center chevron is properly aligned in the sight window.
