ATF classifies rubber bands as illegal machine gun parts.
The Tech branch has classified a particular shoe string design as a MG.

Bump firing is legal. I've seen a few determination letters that said rubber bands are NOT MGs. Rubber bands are often mentioned in multiple determination letters as an approved method of bump firing.

Of course... determination letters are only relevant for the owner of the letter and they can change their position with every letter. Letter writing is frowned upon in the NFA collecting world. Asking the BATFE for these determination letters is making them create policy/law.
The BATFE is an agency who gets to be all three branches of the gov.
