SilencerShop Ruling- What does that mean for Michigan gun owners?

From my understanding (the little I have on the matter), it seems to me that the NFA for SBRs,SBSs and supressors has been rendered non constitutional due to them not collecting a tax anymore.

Now Michigan's law on these items is very confusing for me, ive read multiple things discussing how going forward if you had a stamp before this went into effect you're considered kosher under Michigan law moving forward? Is this true? How will this work?

Will Michigan law impede us from buying all this without a stamp?

This is an exciting time but it still all feels murky for me.

Any help or discussion on the matter would be appreciated
