What are the laws regarding the private sale of rifles between states? Currently I am a resident of NYS (But not NYC), and I am going to be visiting a gun show in Philly March 8-10. A dealer that I frequent suggested that I MIGHT be able to legally buy the rifle (A FS2000 if you're curious) there if I can find a private dealer. Apparently the laws allow you to make private purchases of guns that had been grandfathered in. Does anyone have any insight into this? Also completely off topic... Anyone have an FS2000? what do you think of it?
