It's a "Business Firearms License" which lets you import however the government is stingy about giving those out (and they're only given to established companies for movie props, Mil/LE training supply etc.). Not to mention the costs associated with the actual application (and subsequent renewal costs).

If you're 18 in a few weeks then wait, get AV'ed and take a browse through the Classifieds (once AV'ed). Note that the AV process may take a few days or up to a month depending on scheduling and when the next AV batch is going through (it's a "switch" that's turned on by the site admins so it's not automatic, your AV rep has to manually submit the info (and hope that they get the right spelling of the username)). If the last AV batch was yesterday (and your AV rep missed submitting your info) for example it might take a week or a week and a half to get your AV status updated.
