I recently bought a cheap DVR off ebay for around $55 for use with my Pulsar thermal. It works well but the file size is rather large. It's not 1080p and the avi files seem somewhat large. But I haven't messed around much with software to try to reduce the file size while keeping the quality. I think it's called a "Kelima mini car dvr". I just looked it up and it is no longer listed as that and the seller I bought it from doesn't carry it now. Anyway, putting in a search for "2.5 LCD mini DVR" pulls up results for it at either $67 or $80. It uses the Nikon "B" mini USB plug for charging and standard 3.5mm (or maybe 2.5, I don't recall for sure) jack for video input from the scope. You can make your own cable for the Armasight using the correct plug from Binder. I found it was cheaper to order the plug ends from a supplier in the UK than to order direct from Binder, as Binder's shipping is quite pricey.
