Just sharing my experience, not saying what happend is right or wrong
Last restricted transfer for me, I had called to get a statt and asked about getting it emailed as well as a copy of the registration certificate. I said I wanted to take the gun to the range and didn't want to wait for the reg. she said no prob, emailed me the statt and a TN ( transfer notification ) which has the reg # etc on it and told me I was good to go.
I never actually took it anywhere due to no 7.62x25 in these parts, but right or wrong that's what I was told.
