The Holosun Combo Kit pairs the ARO red dot sight with the HM3X magnifier and hard case for a complete, compact optic system ready for duty or sport shooting. This combination gives you the flexibility to run a 2 MOA dot for fast target acquisition, then flip in the magnifier for extended-range precision — all without the complexity of a single variable-power scope. Both optics mount securely to any 1913 Picatinny rail and co-witness via the included 1.63" lower third mount, keeping your sight picture consistent whether you're building a modern rifle, shotgun, or carbine platform.
The ARO's 2 MOA dot is crisp and quick in close quarters but small enough to hold precision at distance. Pair it with the HM3X magnifier and you've got a versatile 3x zoom option that doesn't require you to commit to a single magnification. The hard case keeps everything protected during transport and storage, so your combo kit is ready to grab and go whether you're headed to the range or the field.
Lower third co-witness mounting puts your red dot at the right height over a rifle stock or shotgun rib, so you can use backup iron sights or co-witness naturally with a traditional sight picture. The 1913 Picatinny interface is the universal standard across modern tactical and hunting rifles, so installation is straightforward on virtually any modern platform.
| Optic Type | Red dot + magnifier combo |
| Reticle | 2 MOA dot (ARO) |
| Magnification | 1x (ARO) + 3x option (HM3X) |
| Mount Style | 1913 Picatinny rail |
| Mount Height | 1.63" lower third co-witness |
| Color | Black |
| Included Accessories | Hard case |
Yes. The ARO and HM3X both mount to standard 1913 Picatinny rails, which are standard across AR rifles, carbines, and most modern sporting rifles. The 1.63" lower third mount will co-witness with your backup iron sights if you have them installed.
Absolutely. The magnifier is a separate optic that flips to the side when not in use. You can mount and run the ARO red dot as a standalone sight, and add the magnifier later if needed.
The combo kit includes the ARO red dot, HM3X magnifier, the 1.63" lower third Picatinny mount, and a hard case for storage and transport.
The HM3X provides 3x magnification, which gives you enough zoom to extend your effective range beyond what a 1x red dot alone can deliver. It's a practical middle ground between running unmagnified for speed and committing to a full magnified scope.
