"I just learned a neat and inexpensive technique for rifling barrels. We will spread the technology around so that it is completely impossible to stop guns from being made."

I went to a school, did some custom machining at work a long time ago and am always interested in such tech. Would be more than happy to receive a link, if there is one.

Make a Factory Quality 9mm Rifled Barrel in your Kitchen Using Salt Water and Electricity (ECM)

"...a decentralized collective of gun designers operating under the group name ‘Deterrence Dispensed’ have perfected a method of producing DIY 9mm barrels which not only match but potentially can exceed the quality and performance of many professional factory produced barrels. The best thing about this method is that this allows you to produce barrels without needing a workshop and can even be made quietly in the comfort of one’s cozy apartment. Along with a $200 Ender 3 3D printer, parts for this setup cost less than $100 and the process of making each barrel takes less than 30 minutes to complete."

I saw this one a week or so ago.
