Product Description
This package includes a ADE RD3-015 Pro Zantitium red dot, Picatinny mounting plate and a rear-sight replacement mounting plate compatible with Sig Sauer P226, P228, P229, and P2022 models by replacing rear sight.
Motion Activated System
The ADE Zantitium PRO (RD3-015PRO) features a Motion Activated System. When powered on, the illumination automatically enters sleep mode after five minutes of inactivity. Any motion or vibration will instantly reactivate the dot at the previous brightness setting. Users may also manually turn off the unit to fully disable this feature.
Multi-Reticle System
Easily switch between three reticle options:
- 32 MOA circle with 2 MOA dot
- 2 MOA dot only
- 32 MOA circle only
The same LED projects all reticle options, so no re-zeroing is required.
- Power: 1× CR1632 battery
- Press & hold DOWN (3 sec): Power ON/OFF
- Press & hold UP (3 sec): Change reticle
- Quick press UP/DOWN: Adjust brightness
Large Viewing Window
The Zantitium PRO offers one of the largest viewing windows in its class:
2.25" L × 1.4" W × 1.27" H
The oversized lens provides a significantly wider field of view—up to nearly twice that of typical micro optics. Due to its larger size, it may appear bulky when installed on smaller compact models.
