Yea Ive been watching that site and budsgunshop but I figured Id see if anyone here had one. Id prefer to deal private party or local shop BUT none of the shops around here can even get an OSS. So it looks like Ill be ordering soon unless someone pops up here before thursday afternoon.
Im pretty sure it works the same way as a new gun. Get copy of FFL with payment, then send to FFL and FFL handles the transfer and I believe you keep a copy of bill of sale and FFL paper for your records.
