FWIW, back in the old days (1980s)the wait was usually one to two years. I sent two Form 4s together for two sub guns. The Swedish K took around nine months and the Thompson took eighteen. It would seem that if one was approved the other would be approved at the same time but things were different back then. I hope ATF is not going back to those "good old days".

It's a good bet it will get slower as Title II transfers will not be on Os priority list.
