Holosun HE509 RD ACSS Vulcan (HE509-RD-ACSS-R)

This pistol sized Holosun Red Dot Sight straightaway allows for a large field of sight and has those features which allow you to sight in quickly and acquire the target and the location you intend to hit.

What’s so neat about the Holosun HE509 is that the entire sight system is fully enclosed in light and rugged aluminum.

Built to provide enhanced environmental protection and abrasion and shock protection, the HE509 Red Dot Sight protective housing stands head and shoulders above an open form reflex form factor.

Note: The 509 ACSS model does not share the same footprint as the 509T (non-ACSS models) and therefore is incompatible with aftermarket mounting solutions and custom cut slides for the 509T (non-ACSS models).
