Actually I went back and looked at the documents I have on this case. The guy pled out to unlawful user of narcotics in possesion of a firearm. His plea deal got him 6 months in the pen, 3 years supervised probation. He forfeited 15 machineguns to the US Government. There were 53 guns involved total, 7 of which were not machine guns (Spas 12, a few sawed off shotguns and 2 pistols). He was allowed to sell these guns to a licensed dealer and receive the money for those other 38 guns, and that number includes 31 machine guns. So these evidence tags, on my gun, the gun in this thread, and all the Ruger guns frank had a while back were not in the group that was forfeited to the government. They were in the group of guns the guy was allowed to sell.
Ole Dan was a narcotics officer and because of this he probably got the sweet 6 month deal and made a ton of money being allowed to sell 31 machineguns instead of them all being seized. The dude had a collection. yeah there were a few low grade guns in the bunch like the M11/9 I bought, but he had things like 3 consecutive M11/9s, Fleming sears, M16s, 8 uzis (part of the forfieture) , 15 Ruger Ac556s, M60, HK MP5s, you get the idea
