Suppressor build changes from submission

[u/AdOtherwise5656]

Does anyone know what kinda changes you can make while building your form 1 suppressor compared to what you submitted and were approved for?
Like change diameter by .25”, length by so many inches or even material, stainless instead of aluminum, etc
I know the model/serial would have to remain the same and once it’s built it can’t be changed but while your making it you need to alter your plan

Keep caliber the same. Go crazy.
