AR lower question

[dats82]

I was told a while back that if you register your lower as a pistol when you buy it, you can build it either as a rifle with a stock and full length upper or as a pistol with no stock and a pistol upper. Can anyone validate this or dispute this for me?

If it is registered as a pistol first, then it has to you have to go the SBR route and pay the maker tax if you want to add a stock. You could add a rifle length upper so long as you don't add a stock.

I thought a pistol lower can be changed to a rifle, but a rifle lower can never become a pistol. I didnt think it had anything to do with SBR unless you tried to put a stock on a AR pistol that had a short barrel. SBR/NFA forms would need to be filed if you wanted to put a stock on a short barreled pistol.

This is the impression I was given.

All of you are right. If you describe it as "other"at the transfer and intend on making a pistol, that's fine.

If you put a stock on it and make it into a rifle, you can do that, too, but you can't go back and make it into a pistol. Kind of hard to know if you actually did that, but it isn't worth it to find out. If you use a 7.5 inch barrel upper and put a stock on the lower,

get the SBR stamp before you do.
