When my dad was in South Africa they offered to take him "outside the fence" where he could buy a fully automatic AK shipped to the states (disassembled) for $15. He says that was before certain import restrictions so it could have been shipped back disassembled. After the NFA tax he could have sold a $215 weapon for several thousand.
He also kicks himself for not buying into many of the cheap gold opportunities he had.
Wow. $15 huh? Sounds like he could have got himself an FFL and rented a little space in the mall!
Sounds like those guns would probably be beat to hell though.
I know what you mean in gold, I had some savings when I got married and wish I would have invested some in it. It's over triple the price it was then and everytime I hear the current gold prices I sigh...
