If you bought your stuff from a licensed dealer, it’s already registered with somebody somewhere. If you didn’t, its a good bet that a firearm is registered somwhere, albeit not specifically to you but possibly to your source who will gladly tell them where he disposed of it when the BATF comes knocking on his door, if necessary.
I haven't figured out what exactly I'm going to do yet, and I have to make some phone calls and such before I can decide. I'll let y'all know what I ended up doing, once I figure out exactly what that'll be.
