QDM150 Side Plate Adapter – 45° Offset RMR Footprint
The QDM150 Side Plate Adapter adds a 45° offset RMR footprint to your existing QDM150 mount, providing a dedicated mounting point for a compatible red dot sight alongside a DNT digital or thermal optic.
The offset configuration provides an alternative viewing position for close-range applications while keeping the primary optic in its existing position.
Requires QDM150 Mount
The QDM-RMR Side Plate Adapter does not function independently. It requires a QDM150 Multi-Functional Quick Detach Mount that is securely installed on the compatible platform.
The adapter expands the functionality of an existing QDM150 setup without requiring a separate primary mounting system.
45° Offset RMR Footprint
The QDM-RMR positions an RMR-footprint red dot sight at a 45° offset beside the primary DNT optic.
This configuration provides an additional sighting option within the same compact setup and allows the red dot to remain offset from the primary digital or thermal optic.
Compatible DNT Optic Systems
The QDM-RMR Side Plate Adapter is designed around the QDM150 mounting system, making it compatible with QDM150 configurations used with:
- HYDRA
- ThermNight
- ZULUS HD
The adapter itself requires the QDM150 to function.
Rugged 6063 Aircraft-Grade Aluminum
The QDM-RMR Side Plate Adapter is machined from 6063 aircraft-grade aluminum alloy and features a hard-anodized matte black finish.
At only 40.5g / 1.43oz, it provides a lightweight addition to a compatible QDM150 setup.
The adapter is rated to 800 Gs / .50 BMG recoil and is specified for operating temperatures from −20°C to 50°C / −4°F to 122°F.
