You can, sort of. With electrochemical machining you can make a barrel at home for under $200 in tooling (plus the 3D printer). Basically you 3d print a mandrel

You can, sort of. With electrochemical machining you can make a barrel at home for under $200 in tooling (plus the 3D printer). Basically you 3d print a mandrel for the rifling, and run copper wiring through the grooves of the mandrel. You then run electrified saltwater through the tubing and it will cut the rifling.
It's stupid simple to do, and the people who have tried it have gotten results comparable to factory barrels. So probably won't win a shooting competition, but definitely good enough.
- snapetom 4y agoLol. Holy crap. I've been out of the AK making game for too long and didn't know about this. I'll have to look it up.
- Ancapistani 4y agoLast I checked, you could mostly find references to ECM in reference to the FGC-9. I played with when it was first published, and successfully made a rifled barrel blank. I’ll probably do it again at some point, to comply with the NFA for some other projects I have in my backlog - smoothbore pistols are considered “Any Other Weapons”, but even rudimentary rifling is enough to make it “just a pistol”.
- jasonwatkinspdx 4y agoI stumbled onto a youtube video demonstrating how to make a gun very similar to what was used to kill Abe in Japan. They used this for the barrel in the video and it's surprisingly simple and controllable, or at least was to me.
