Ive actually seen a show that had airsofts in it. Although they were supposed to be real ak47's in the show, they still had the "Warning blah blah blah "sticker clearly shown on the gun.
Also in the movie inside man, they break into the bank with ak47's and
SPOILER ALERT FOR INSIDE MAN
when they are finished, it turns out to be fake toy guns (airsofts) of ak47's. Although they were clearly not during the bankrobbery, they magically switched to toys in the end (the wood was the real tattle tale).
