Question: what is the difference between form 1 and form 4?
Answer: The wait times for the ATF Form 1 vary depending on ATF's backlog but they generally take at least a few months. The good news is that they are almost always faster than an ATF Form 4. This means that it is faster to make your own SBR on a Form 1 than it is to buy an SBR on a Form 4.
