Mounting the NANO

The NANO uses the RMS/RMSc optic footprint, which is compatible with a wide variety of optics ready concealed carry pistols. These typically have thinner grips and slides than most duty pistols.

For the Glock 43X/48 MOS, S&W Shield Optics Ready, Sig P365 Optics Ready, and Springfield Hellcat Optics Ready models, we include the correct mounting screws in the box.

If your pistol is not optics-ready, we recommend getting an optics-ready slide or using an adapter plate like the C&H Adapter Plate for maximum compatibility.

Below is a non-exhaustive list of pistols that the NANO is compatible with. This is not a complete list, as there are many mounting solutions available. If you know of another pistol that the ARO-MINI fits on, please email us that information at support@at3tactical.com. If you have specific questions about the ARO fitting on any pistols, please contact the gun manufacturer directly.
