I think you’re underestimating how stupid people are because of the group you socialize with. People with the will and skill can make one this isn’t trivial even with all the videos in the world it will take weeks of practice and will require a good understanding of chemistry and basic engineering. Most common criminals wouldn’t know how to measure correctly, use a caliper, heck most of them won’t be able to multiply add or subtract correctly. Yet alone hammer forge an AK receiver out of a shovel. Even if you discount career criminals as the only risk group most people can’t wire a power socket, switch a lock or fix a leak you want them to forge recievers and cut grooves in barrel blanks? Not to mention that any substantial delay would reduce the likelihood of these guns being used there is a huge difference between a kid that would have to spend 2 weeks banging a gun out in his garage and a kid that can go into the school workshop and 3D print a gun on the spot.
