Question about in state transactions

[marv]

hey there guys
i was wondering if you could all help out with something
another member and i are trying to do our research to see if it is possible to ship a stripped AR lower from him (individual-non ffl) to me (also individual non ffl)

we know you can ship long guns, but since the AR lower can also be a pistol (which is not my intended purpose) can he still ship it to me?

any help would be most appreciated

edit: both indiana residents
edit: here is the ATF FAQ where i found my information
May a nonlicensee ship a firearm through the U.S. Postal Service?

Call your ATF Field Office and ask them.
