    Can I gift a finished 80% lower?
    Pretty sure this has been hashed out several times already. You can certainly gift a finished gun from an 80% lower. Engravings are not mandatory. If the reciever of the gift lives in a different state you will need to use an FFL for the transfer.

    What makes 80% lowers legal to finish?
