ATF has advised NOT to send/supply a 'private party' (seller) with a copy of my FFL. Give the sender the first three and last 5 digits of the license number and have them use E-Z Check. These 'private sellers' are convinced they need a copy of the FFL before they can ship. A Federal Firearms License holder does, but a "private seller" does NOT. If the private seller uses E-Z Check and only ships to the address given on E-Z Check he has done his 'due diligence'. He should download the E-Z Check 'results' page. A 'private seller' shipping a firearm is the same as shipping your rifle/shotgun/handgun to a Licensed gunsmith for work, except in the case of a sale, the firearm can not be shipped directly back to the 'private seller' if the buyer decides he doesn't want the firearm. Confused yet? That's the way it's been for a long time. Except the 'private sellers' are convinced they need a copy of the receiving shops' FFL. They don't understand the laws/rulings. ATFE enforces firearms laws/rulings, not the 'private sellers', so,,,, I think I'll go what ATFE directs me to do, not what the 'private sellers' think needs to happen. Many of these 'private sellers' have become too much hastle to deal with, hence the refusal to do 'business' with them. On top of that, seems there might be a lot of other potential issues when dealing with an unLicensed seller who is half or two thirds of the way across the country.
