I watched the video but what does it actually mean for us that purchase guns and suppressor? I need the dumb persons breakdown.

I think the bottom line is that we have to wait for the appeal to play out. Hopefully the district court will be affirmed and then another case brought on 2A grounds against NFA

Eventually it means going to an outdoor store and buying a suppressor like you would a box of ammo.

The judge gave the government 7 days to appeal the decision.
The judge ruled that when the government made the tax $0, it no longer justifies the the paperwork associated to the tax, no form 4, no fingerprints, ect. for suppressors, short barreled rifles ...
The judge ruled that the government could not use the commerce clause to continue the paperwork requirements, only congress could do that in a new law.
The judge also found that "other weapons" petitioners did not have standing as they joined the suit after the filing.

If the government doesn't appeal within 7 days, the ruling will only apply to partitioners current and future members; not universal across the nation.

The judge did not render an opinion on the constitutionality of the entire NFA as the opinion addressed the narrowest of the topics asked for by the petitioners.

So now, the petitioners and their members wait on the government to take their next actions.
