Holosun SCS 320 Green Dot Sight Multi-Reticle System Solar Charging – SCS-320-GR

The Holosun SCS 320 Green Dot Sight is the no-battery-tray enclosed green dot sight, purpose-built for SIG Sauer P320 optics-ready slides. Its Solar Charging Sight (SCS) system runs on an internal rechargeable cell topped up by ambient light — there's no removable battery to ever swap. It direct-mounts to P320 optics-ready slides with no adapter plate.

The sealed, enclosed emitter keeps the green dot protected from dust, lint and debris — a real edge for carry and duty. Holosun's Multi-Reticle System offers a 2 MOA dot, 32 MOA circle or both, with fully automatic brightness.
