I only have the two scopes so don`t really know much about helmet mountable options but just pointing out that for the price difference some decent digital nightvision are usable and you don`t have to worry about light source damage.  Sure they won`t be as clear and you will really need the ir illuminator on for them to be affective but they are an cheaper option and are usable at closer ranges without alot of heavy foliage.

What lid are you running? I'm looking at night vision down the line, but I knew my first purchase had to be a proper helmet. Didn't fancy hanging £3k off the front of a £50 Chinese repro!

I'd go with a FMA helmet (Maritime) as I bought a Norontos Mount, which fit on the helmet perfectly.  (I've since bought a airframe clone but the helmet shrougd was crap and the Norontos mount wiggled..I just took off the FMA shrough and bolted it to the Airframe.  **Norontos is a the metal mount which attaches both the nightvision device and helmet together.  Bungee cords you see on helmets are used to attach to the night vision device to remove any loose play when it pulled down and in front of your eye. 

 https://www.scottcountry.co.uk/night-vision/monoculars/ These guys are very popular in the community and they offer finance deals on most of them.  (Though they don't have much stock atm...)  https://www.reddit.com/r/NightVision/ This reddit is mostly American but a lot of uselfull info can be found here...there are UK people who post on here as well.  http://www.nightvisionstore.co.uk/tubed-c102x2376934 Another UK nightvision source, but unsure if they offer finance.  https://www.nightvisionforumuk.com/index.php UK Nightvision forum...can be helpfull.    

https://nighttec.net/ EU shop and have a lot of NV stuff..but expensive.  Facebook groups can also be handy as a lot of people selling NV devices or associated bits...like J-Arms & mounts etc.  "Real Steel Advice and Sales"   "Tactical Kit and Accessories Sales Uk (Real Steel Only"   I hope this above can help you on your NV journey... 

The trick is not only buying a device, but finding a way to mount it to a helmet.  For me personally... I bought a Armasight Sirius SD Gen2.5+ monocular for £1300 on finance with ScottCountry.  (They don't sell them anymore)  Problem I had is I bought a Norontos mount and J-Arm.  The mount fit into the NV shroud on my FMA helmet perfectly.. I could not break it away and it was locked in solid.  The J-Arm (Which attaches the mount and device together) was designed for a PVS-14 monocular and the mounting rails were different.  I didn't want to buy the Armasight (Now FLIR btw) mounting kits etc...as they were very expensive and had shit reviews.   

I did find on google a company who made an adapater so I could mount my NV monocular to the J-Arm and bosh..it's was sorted and is running strong to this day.   A lot of people these days buy the Aluminium FMA G24 mounts with the dovetail...but as you research more into NV you will find out what I mean.  Have a butchers at the HERESEYGROUP on youtube and look for their NV vids..can be informative about the basics.. 

Don't waste your money on GEN1+ devices...better to save up for a GEN2+ or finance it.   Good Luck!
