DTD A4 Lightweight Night Vision Mount (LWNVM)
DTD A4 Lightweight Night Vision Mount (LWNVM)
Every gram on your helmet is paid for by your neck, and the mount is one place where good engineering buys weight back. The DTD A4 LWNVM is a dovetail helmet mount of no more than 140 grams, in high-strength aerospace aluminium hard anodised to military specification, with matte black fibre-reinforced polymer. Folded, it sits close against the helmet and keeps the centre of gravity low.
It operates and adjusts with one hand. Dual-axis adjustment and locking accommodate different eye distances; they clear gas masks and protective goggles. The mount returns precisely to your set near-eye position after repeated folding and unfolding. A safety release detaches the mount from the helmet base automatically if external force or g-load exceeds the safety limit: less chance of entanglement with cords or foreign objects, and a lower likelihood of neck injury while running or parachuting.
The dovetail slot locks any device with a standard Wilcox dovetail, from the BNVD, PNVG and GPNVG families to the AN/PVS-14, AN/PVS-31 and DTNVG/DTNVS. The mount fits all FAST helmet bases. Ask us before ordering if unsure about fitment.

Questions before you buy
Which devices does it take?
Anything with a standard Wilcox dovetail. The compatibility list includes BNVD-31, 1431/MK2, 931, PNVG-18, NG-31, AN/PVS-14, AN/PVS-15, AN/PVS-18, AN/PVS-31 variants, GPNVG-18, DTNVG, DTNVS, BinoNV and more. Custom mounting accessories can be made for other devices; ask us before ordering.
Does it fit my helmet?
It is compatible with all FAST helmet bases.
What does the safety release do?
If external force or g-load exceeds the safety limit, the mount detaches from the helmet base automatically. That prevents entanglement with parachute cords or foreign objects and reduces the likelihood of neck injuries during activities such as parachuting and running.
Export and delivery
Export and delivery
Night vision and thermal devices ship to Switzerland, Liechtenstein and EU/Schengen countries only. Deliveries outside Switzerland and Liechtenstein require a signed End User Certificate: after payment we send you the certificate, you sign and return it, we complete Swiss export clearance, and your device is dispatched with tracking. If clearance cannot be obtained for your country, the order is refunded in full. Spare parts and accessories are not controlled goods: they ship without a certificate. Collection at the Villmergen showroom, by appointment, is free of charge.
