Holosun ARO CORE
The ARO-CORE (Advanced Rifle Optic Core) is the next evolution of Holosun’s proven micro-optic platform, building on the popular 20mm 403 and 503 series with a redesigned 22mm housing for an improved sight picture and enhanced compatibility.
Designed to pair seamlessly with Holosun magnifiers, the ARO-CORE includes a 1.63″ lower-1/3 co-witness mount as standard, along with a secondary 1.05″ mount for flexible setup options. Compact, rugged, and equipped with advanced electronics, the ARO-CORE delivers fast target acquisition and dependable performance across sporting, defensive, and professional applications.
Available in Red, Green, or Gold reticle colours, shooters can choose between a precise 2 MOA dot or Holosun’s versatile Multi-Reticle System (MRS) for maximum adaptability.
