"For Wisconsin residents only as law dictates residents of your own state can only buy."
Squirrel,
What law? Federal or Wis state? I know of no such law, I sell through FFL's via the I-net to people in all states.
I was in Wis 3 years ago and bought 4 guns, 2 from FFL dealers and 2 from private sale. At no time did I break any law.
