I know you are prob saying... AGAIN!!!

I am posting for a "friend" who just setup a NFA trust. He is in the process of applying for his stamps.

Are the steps basically the following to convert his non NFA 16" AR15 to a SBR:

1. Get lower engraved
2. Buy 11.5" barrel
3. Fill out form 1, fill out details with SN, trust info, barrel length, rifle details, etc
4. Mail form 1 with copy of trust with revised schedule A and $200 check
5. Wait
6. When stamp arrives, swap barrel
7. Enjoy


Sorry if this is a stupid question, I told him I'd help "him".

TIA
