The Primary Arms 507K Red Dot Sight with Red ACSS Vulcan Reticle is purpose-built for shooters who demand precision on compact and slide-mounted platforms. Designed around the Holosun 407K/507K footprint, this optic serves law enforcement, military personnel, and defensive shooters requiring fast target acquisition on pistols and compact rifles.
The anodized black finish provides durability against environmental stress while maintaining the low-profile form factor essential for duty and carry applications where sight height over bore and reliability are non-negotiable. Built on proven Holosun internals, the 507K delivers reliable parallax-free aiming through its advanced lens system and sealed optical chamber.
This configuration provides the durability standard in professional duty optics while maintaining subminiature dimensions ideal for appendix carry and compact slide real estate. This sight is optimally suited for Glock MOS platforms, SIG Sauer P365/P320, Smith & Wesson M&P Compact, and other pistols with RMSc or Holosun 407K/507K mounting patterns.
