Firearm" means a weapon or device from which a projectile or projectiles may be fired by an explosive such as gunpowder.
No one is trying to be clever or skirt the law, but follow it to the letter, and we are only discussing as a hypothetical situation, but it seems crystal clear that under WA law (which is all 594 applies to), that a stripped lower is not a firearm. If you are crossing state lines then obviously Fed law would apply.
Now to me when you are talking about a complete rifle minus a bolt or firing pin, then you are in a much grayer area because the word "may" in the definition of firearm under the RCW could open to interpretation.
