THE COLES NOTES:
How it concerns you, Basically anything that is "weapon" or "arms industry" related may be export restricted.

If you are Canadian Items costing <$150 at wholesale are exempt from ITAR IF they have fair civilian use. If you are from the UK that exemption is $500. Some items are very strictly monitored and controlled IE Night vision, laser systems.

Many US retailers are aware of the exemption and file bulk paperwork for you as part of the sales agreement IE brownells,SKDtac if you are buying Rail systems, rifle mounts, mags,tactical nylon etc. In other cases US retailers are completely uneducated about ITAR and simply use it to block or not bother dealing with international customers

Some things are ITAR controlled and you wouldn't even know about it. I got nasty letter 8 years ago for buying O-rings total price (<20.00) that happen to be the correct size for AEG pistons, that just happen to also be used in ICBMs.

ITAR is not limited to guns, and gunfighting gear, software, computer hardware basically anything that can be used to support warfighting -CAN- be considered ITAR.

As far as recreational shooting sports go optics are the big ITAR no-no, even though their is legitimate civilian use for these items. If you want to buy yourself a REAL eotech/aimpoint. Look in country first unless you are willing to deal with paperwork.
