90° Flip
Stow or deploy in one motion

The QDF flips your thermal or NV out of the line of sight without removing the device. Stack it with a Falconclaw QDA for a 1.63 in / 41 mm optical centerline. 66 g, made in Estonia.

Mount only — no QDA included

The QDF is just the flip mount. To attach a thermal or NV device, you’ll also need a Falconclaw QDA for that device — sold separately.

Flip in one motion Stow or deploy the optic without tools. Same lockup every time.
Rifle and helmet The QDF (rifle), QDB (helmet bridge) and QDM (J-arm) all take the same QDAs. Transfer your device between them in seconds — no tools.
Universal compatibility Fits any thermal or NV monocular that has a Falconclaw QDA.
Built tough Aluminium 7000 + stainless steel, MIL-A-8625 type III hard anodised. 66 g.

The QDF

Optical Centerline

The optical height of your device above the rail depends on whether you run the QDF alone or stack a Unity-spec riser underneath.

1.63 in
41 mm
Default — QDA + QDF + device

Measured from the top of the rail. The Falcon 640+ V2 + QDA + QDF stack puts the optic at exactly this height. Suits most builds running a low-mounted day optic alongside the thermal.

2.26 in
57.4 mm
Unity height — with the FAST Optic Riser

Add the FAST Optic Riser under the QDF and the optical centerline rises to the Unity standard. Use this if you want to co-witness with a 2.26 in / 57.4 mm height day optic.

Frequently Asked Questions

Just the QDF mount itself. To attach a device you also need a Falconclaw QDA for that device, sold separately. One QDA per device — the QDA bolts to the device and gives it the dovetail interface that snaps into the QDF.

Pick Your QDA ↑

Yes, you can — but most night vision tubes aren’t rated for recoil higher than 5.56. On larger calibres, the recoil shock can cause permanent blems on the image intensifier tube. Falconclaw does not recommend mounting an NVG on a firearm. If you understand the risk and still want to do it, we’ll sell you the QDA — but the tube damage isn’t covered under warranty.

QDA + QDF + device gives you exactly 1.63 in / 41 mm measured from the top of the rail. To raise it to the 2.26 in / 57.4 mm Unity standard, install a Unity accessory riser under the QDF.

The QDF itself is a rifle-side flip-to-side mount. For a helmet build, pair it with the QDB (Quick-Detach Bridge) — the QDB carries the device on the helmet and the QDF lets you stow it to the side when not in use.

Designed and manufactured in Estonia. Aluminium 7000 + stainless steel, finished with MIL-A-8625 type III hard anodising.

Not sure what to pair with the QDF? Tell us your device and use case — we’ll confirm which QDA you need and whether you want the Unity riser.
