A statement to the effect you'll be using it on your toy airsoft gun might work, but the regulations are there and in place if customs decides to be picky.
The problem, is that I haven't ordered my "toy airsoft gun" yet. I suppose I could tell them if they come knocking that the parts are for my paintball Type 56 AK. I ordered the items two weeks ago and still haven't got them. Maybe they did get seized?
