Pvs 5-31 Nvgs

*Helmet for illustration only and NOT INCLUDED* PVS 5-31 conversion. Unfortunately I don't have spec sheets for the tubes but the original setup was a Litton M908 which has Gen2 tubes and is a PVS-5 variant. This unit was not functioning when I got it but turned out to be a minor wiring issue which I repaired. I carried out alot of work cleaning, repairing and then designing a new PVS 31 style arm setup to house the original parts. The main structure of the arms is polymer and the adaptor brackets are 3D designed and printed in Carbon PETG which is a tough and durable material. I incorporated the original switch and IR led so it can be turned on as normal and the IR light provides light in fully dark conditions. The battery housing can take 2 x CR123a battery's which are wired in parallel so you get double the running time of the original setup. If posting buyer pays postage and PayPal fees
