Buying a barrel on Ebay

[Chewy65]

I maight bid on a used barrel for sale on E-bay. Possibly a slide with a barrel, guide rod and spring. Can that be legally imported and, if so, must the barrel be delivered to a FFL? The slide would not have a LCI..

It depends if the seller will ship to CA.
I have seen some sellers no longer ship to CA. on Ebay/GunBroker
