Considerations & Trade-offs
- Requires a 1" Weaver or MIL-STD-1913 rail, so it is not a universal fit for every setup.
- The 7mm raised quick detach base is designed for lower 1/3 iron sight co-witness, which may not match users who prefer a different sight height or sight picture.
- Night vision use is supported, but the optic’s brightness range includes separate daylight and NV settings, so setup and adjustment matter depending on the shooting environment.
- It uses a single CR123 battery, so continued use depends on carrying a compatible spare power source.
