The lightest NV bridge on the market

The QDB lets you dual-mount thermal + NV, NV + NV, or thermal + thermal on your helmet — same QDA interface as the QDF and QDM, so you can transfer devices between rifle and helmet in seconds.

Bridge only — no QDAs included

The QDB is just the bridge. To attach devices, you’ll also need a Falconclaw QDA for each one — sold separately. For a thermal + NV setup, that’s two QDAs: one for each device.

Dual-mount Run thermal + NV, NV + NV, or thermal + thermal on a single helmet bridge.
Articulating with IPD stops Swing devices out of your line of sight or fold them against the helmet. Adjustable IPD stops return them to the same position every time.
Quick-detach to rifle or hand Same QDA interface as the QDF and QDM. Transfer a device between helmet, rifle and handheld in seconds — no tools.
Built tough Aluminium + stainless steel, MIL-A-8625 type III hard anodised. 58 g.
Ships WorldwideNext business day from Estonia. No export licence needed.
Trusted Worldwide4.9/5 on Trustpilot — 278+ reviews.

The QDB

Why dual-mount?

NV and thermal each cover what the other misses. Running both on the same helmet means you don’t have to choose — switch in the moment, or use both at once with the QDB’s articulating stops.

Strengths
Night Vision
  • Short to mid-range identification
  • Detail clarity
  • Navigation
  • Passive and active aiming
  • Tactical maneuvers
  • Driving
Strengths
Thermal
  • Long-range scanning & detection
  • Usable in zero-light conditions
  • Heat signatures can’t hide
  • Works through rain, fog, snow, sandstorms
  • See through smoke

Helmet Compatibility

To attach the QDB to your helmet you need a dovetail mount fitted into your helmet’s shroud. The QDB clips into any standard dovetail mount that fits these shrouds:

Wilcox G24
Standard dovetail — native fit
Cadex
Standard dovetail — native fit
Argus
Standard dovetail — native fit
Other dovetails
Most standard NVG shrouds work — ask if unsure

Recommended Helmet Mount

We recommend the UDAPT F25 — combat-proven, made in Ukraine, fits standard NVG shrouds.

Compatible Devices

Pick the QDA for each device you want on the bridge. For a dual-mount build you’ll need two QDAs — one per device. Common pair: a QDA — Falcon 640+ V2 on the thermal side, a QDA — PVS-14 on the NV side.

Frequently Asked Questions

Just the QDB bridge. To attach devices you also need a Falconclaw QDA for each one — sold separately. For a dual-mount build, that’s two QDAs (one per device). The QDA bolts to the device and gives it the dovetail interface that snaps into the QDB.

The QDB clips into any standard dovetail helmet shroud — that includes the Wilcox G24, Cadex, Argus, and most other NVG shrouds on the market. If you’re running a non-standard shroud, contact us with the model and we’ll confirm fit.

Yes — the QDB is configuration-agnostic. Run NV+NV for stereo depth perception, thermal+NV for the most common dual-mode build, or thermal+thermal if your mission needs it. You just need the matching QDA for each device.

Yes. The QDB has integrated, adjustable IPD stops — once you’ve set your inter-pupillary distance, both devices return to the same position every time you flip them down.

Yes — that’s the whole point of the QDA system. The QDB, QDF (rifle flip-to-side mount) and QDM (J-arm) all use the same QDA interface. Pop the device off the helmet bridge, snap it into the rifle mount — in seconds, no tools.

Designed and manufactured in Estonia. Aluminium body + stainless steel hardware, finished with MIL-A-8625 type III hard anodising.
