People that built 80% pistols had to serialize and register them with the state.
To the best of my knowledge no one successfully legally built a semi auto pistol from 80% since then.
There is one viewer on YouTube that in comments discussion claimed that he has done it successfully 4 times. Though the stuff he said makes no sense.
For example he said that only a certified gunsmith would serialize your 80% after an inspection. That is incorrect.
Then he said that he takes his builds to a sheriff who will put 600 rounds through the build and do various drop safety tests and then sign off on it.
That is completely incorrect.
I built my registered SBR from a 80% lower, used a dremel with a small round cutting bit to do the S/N and other required info…ATF nor anyone else ever wanted to see it…
Yeah, if the stuff that I’ve signed up for email notification of it being back in stock, starts showing up at about the same time, my budget is toast.
Edit: A day later and my budget is already complaining, after finding two of the items I had been looking for (one of them the most expensive one on my list) available again.
