The Holosun ARO (Advanced Rifle Optic) is an advancement on the popular 20mm 403 and 503 series optics. ARO features an all-new 22mm housing design that mates perfectly with Holosun's magnifier series and an all-new 1.63” lower 1/3 co-witness pedestal mount.. This version of the ARO features a 2 MOA dot with the option of a red (ARO-RD2), green (ARO-GR2) or gold (ARO-GD2) reticle.
The HM3X is an aluminum bodied 3X magnifier designed for use in conjunction with a red dot sight. The HM3X is feature-packed and includes a quick release, ambidextrous, flip-to-side Picatinny rail mount. Holosun includes a spacer with the HM3X that provides compatibility with absolute and lower 1/3 co-witness dot heights for maximum compatibility. The HM3X has a generous 2.75” of eye relief, is IP67 certified water resistant, and includes windage and elevation adjustment for precision zeroing to your optic’s zero.
