Pistol upper legal to own?

[ike838]

Why are you even worried with a 16 in. barrel? That is a rifle not a pistol. SBR is less than 16 inches.

I was not worried about the 16" barrels. Just examples of parts I have on hand.
I am considering getting a pistol upper to add to the pile as well.
I have two unbuilt lowers that were transfered as "Other".
As I stated earlier I will just build one of those with a brace, buy the pistol upper and take a few pictures to avoid any gray areas.
