Two ffl holders locally require it to come from another ffl holder. One says it is the law. I quit buying new guns from him after arguing about it. Another said he knows it isn't the law, but the local ATF agent made it clear she wanted it done that way.
That seems to be the deal here in East Central Georgia. Got exactly the same response from 2 or 3 FFLs when asked if they would accept transfer from individual. Doesn't make it right but it is the reality in which they work.
I got this from a new gunshop locally as well. "ATF says we shouldn't". Could be an ignorant inspector, could be gunshop owner misunderstood, or could be gunshop owner was lying to me. They don't get any of my business after that, regardless.
