Public cannot access black/metal guns. I cannot buy one even if I wanted. Only those AV'd by asc can buy black/full metal guns. The fact that asc has them in classified adds does not mean they are 'out there' and you can get around AV. Those who obtain them for asc are do so under a 'no questions asked' policy, of course you know make of model and specs. But we do not ask, so that in the event that someone wants to charge you for buying it you can say 'I was not told how it got in country'. Also the FAQ is sufficient that a non-AV'd member such as myself can understand this and adhere to it with out having to post the six hundredth thread on the topic
