ADM DNT Hydra Thermal QD Base — Fast, Secure, Repeatable
Elevate your DNT Hydra thermal optic setup with the ADM QD Base — engineered for fast detach and secure reattachment while maintaining a repeatable zero. American Defense Manufacturing’s patented Auto Lock™ Quick Detach Lever system ensures strong rail engagement even on “out-of-spec” picatinny rails — ideal for adapters, bipods, and rail wear.
Machined from 6061-T6 aluminum and finished with Mil-Spec hard coat anodize, this base is built to endure harsh conditions without compromising strength or precision. The mount provides a 1.54″ centerline height, aligning well for both direct view and clip-on deployments.
This base is compatible with Hydra, ThermNight, and ZULUS HD optics — making it a flexible, high-quality mounting solution for your thermal system.
