Description
The Holosun ARO-RD2 + HM3X combo pairs the enclosed Advanced Rifle Optic with Holosun's 3x flip-to-side magnifier in one hard-cased kit — 1x speed up close, a flick of the wrist for magnified ID at distance.
The ARO runs a crisp 2 MOA red dot in a sealed 22mm-window enclosed housing on a 1.63in lower-1/3 pedestal mount, with Shake Awake and up to 50,000 hours from a CR2032. The HM3X adds 3x with generous 2.75in eye relief, adjustable diopter and an ambidextrous QD flip mount (absolute + lower-1/3 spacer). Both IP67.

Frequently Asked Questions
Do the heights match?
Yes — both sit at lower-1/3 co-witness height (the HM3X includes a spacer for absolute setups too).
Is the ARO enclosed?
Yes — a sealed emitter housing protects the LED from rain, dust and debris.
Can I remove the magnifier?
Yes — the QD lever detaches it in seconds, or flip it aside to shoot 1x.
