ITAR restrictions have to be the most misunderstood, confusion, bullshit legislation on this planet.
Pretty much every manufacturer and retailer interprets it differently, with most folk too scared of it to take the risk.
Ive researched it a lot and as far as I can tell something is only ITAR restricted if it's supplied to the military.
Ive personally had Leupold, Burris and Vortex scopes shipped to me in New Zealand, none of the models being ones supplied to the Military.
On the other hand I wasn't able to import a Blueforce Gear 2 point sling as it is supplied to the military, but Magpul is fine despite them both being made of nylon webbing and plastic fittings.
Basically if you want to know if something is ITAR restricted, ask the manufacturer.
A lot of items can't be exported not due to ITAR, but due to the manufacturer not allowing certain retailers to export their products, Leupold are notorious for not allowing export.
