I'm ready to file an eFile Form 1 for SBR. I have a decent shooting Bushmaster carbine that I could use as the host lower. Or I could obtain a new "80%" lower.
Questions:
1. If using the Bushmaster lower, when I file do I use that lower's serial number on the Form 1?
2. If using an 80% lower, do I invent my own serial number to use on the Form 1?
