When you buy a stripped lower from an FFL it's recorded in the Acquisition and Disposition Book simply as a 'receiver'. Caliber is recorded if it's marked. However if it's a 'multi' then it's recorded as n/a for caliber.

On the 4473 Firearms Transaction Record the stripped lower is listed as 'other' as it is neither a pistol or a rifle. At least that's the way it's supposed to be.

Since Texas has no pistol registry, that makes it very simple for all of us. It only gets sticky if you take what was built as a rifle and convert it.

ATF Ruling 2011-4 lays out the case:
