Yes. So what if the atf wants to see it. That doesn’t happen btw. Once you take the stock off it’s a pistol if it started out as a pistol. You’re just selling it as a pistol at that point. They like you to notify them if you do sell it as such but that’s not really a law .So even if you registered it, and it is now an SBR, you can just pull the stock off it and it's a pistol again? What if the ATF wants to see it?? Do they then get you for selling an SBR without their permission and tax??
