If your build began life as a factory complete lower that was sold independent of an upper?
The term “Pistol” means a weapon originally designed, made, and intended to fire a projectile (bullet) from one or more barrels when held in one hand, and having:
a chamber(s) as an integral part(s) of, or permanently aligned with, the bore(s);
and a short stock designed to be gripped by one hand at an angle to and extending below the line of the bore(s).

Now a complete lower never wed to an upper has no barrel, either 16 inches longer or shorter. So that doesn't seem to define it as a rifle, SBR, or pistol.
So what we then have is the presence of a stock. Does that alone classify it as a rifle or SBR even if its never had an upper attached?
Can the stock be removed and a pistol buffer tube attached BEFORE mounting a pistol upper and have it qualify as a pistol, or would the initial presence of a stock limit its use to a rifle or an SBR forever more?
The reason I ask is there are some great deals out there on complete lowers, PSA blem lowers for $129.99 with free shipping.
Apologize if its a dumb question.
