Holosun HS507COMP Competition Red Dot — ACSS Vulcan MRS Reticle, RMR Footprint

ACSS Vulcan is a Primary Arms-patented reticle: a small precision dot at the center surrounded by a larger ring that helps fast acquisition under stress. The MRS (Multi-Reticle System) lets you cycle between just the dot, just the circle, or the full Vulcan setup — choose whatever fits the stage.

In USPSA, the 507COMP is legal for Carry Optics and PCC divisions. For IPSC Production Optics check your federation's current rules — divisions vary. For Steel Challenge, it's allowed in Open and Carry Optics categories. Always confirm with current rulebook before a match.

Press and hold both brightness buttons to cycle through the three reticle modes. The optic remembers your last setting between power cycles.

The 507COMP adds a larger window (better for competition transitions) and the ACSS Vulcan MRS reticle (versatile for ranging or fast acquisition). The standard 507C has just dot + 32 MOA circle and a smaller window. If you're competing, COMP. If you're CCW, the 407C or 507C are smaller.

Holosun backs the 507COMP with their limited lifetime warranty against defects in materials and workmanship.
