it is a license that allows purchase of very old and out of date firearms without a FFL. Not technically correct. YOU become the FFL dealer. They ship the firearms directly to your home (or business) address. We're required to keep records akin to your standard FFL dealer. We just get around the $20-$50 transfer fee most FFLs charge.
This will just mean that the price of Mosins and Mausers will go up, I believe.
