Holosun ARO-RD2 & HM3X Combo Kit with Hard Case ARO-RD2 & HM3X

Upgrade your optics game with the Holosun ARO-RD2 & HM3X Combo Kit. This premium package pairs the ARO (Advanced Rifle Optic) with the HM3X 3x Magnifier, all housed in a rugged hard case for secure transport and storage.

The ARO is a refined evolution of Holosun’s popular 403 and 503 series, now featuring a 22mm housing for a wider field of view and enhanced target acquisition. It includes a 1.63" lower 1/3 co-witness pedestal mount for ideal alignment with standard AR-height iron sights and seamless integration with magnifiers.

Perfectly paired with the HM3X flip-to-side magnifier, this combo delivers fast transitions between 1x and 3x magnification—ideal for both close-quarters and mid-range engagements. The ARO-RD2 is also compatible with Holosun’s new lens cover and anti-reflection device system (sold separately), offering even more versatility for serious shooters.

Whether you're upgrading your AR platform or building a versatile sighting system from the ground up, the ARO-RD2 & HM3X Combo Kit delivers exceptional performance in a durable, field-ready setup.
