The lower is peanuts.
It's not much of a firearm, it's just a box for linkage.
US law on that part is exception to the rule elsewhere, that the firearm is the bit where the bullet sits when it goes off.
Bit of a joke if you ask me.. The lower is much easier to fabricate, a lot less problematic if it's poorly made..
Rest of the world, with "real" gun laws.. the barrel and bolt/receiver will be considered the Firearm.
And it's almost impossible to make those to the level of quality needed for a semi auto and still accurate firearm..
Sure you could fab up an open bolt stengun like thing.
and you might manage to fab up something for .45 or 9mm handgun rounds that doesn't explode in your face. But it won't have decent rifling so it's just a spray gun.. not a rifle..like an AR15 would be.
That's doable the pressures are sufficiently low that you can do with a good spring and no locking mechanism..
To try and make your own semi automatic 556 rifled barrel, chamber it, and have a working semi or full auto bolt/receiver that's beyond the capabilities and equipment of most DIY enthousiasts...
