Hey para. They're a mix of real (still rare) and replicas.
Replicas can be bought from flecktarn, Wolf Armouries, 6mil... Loads of places. Pays your moneys, takes your choice etc. Krylon comes from 6mil or Fire Support.
Accessories such as nvg mounts, lights, goggle straps and all that tat can be bought from ebay. Real MICHs are availible on ebay, though never from the uk. Accessories maketh the helmet, so chose wisely
:edit:
Nice lid Hivemind and you're O-neg, best blood type in the world (for others ).
