> it wouldn't stop them from getting guns
Maybe I'm overestimating the difficulty of making guns. But I'm aware of zero conflicts in which small arms were manufactured in situ. Even in e.g. Myanmar/Burma. The fact that even remote conflicts go through the trouble of importing arms suggests this might be more difficult than you suggest.

These are centuries-old objects. Manufacturing technology and materials science have advanced nearly 100 years since Ma Deuce first rolled off the line. Society didn't get dumber, and manufacturing has only gotten more accessible.
Just look at the current state of 3D printed firearms: they're completely useful and viable. CNC machining has never been cheaper or easier to do.
You're not addressing the argument before you, once again
I'm fascinated by your point on Myanmar/Burma since I'm quite sure you used that point since it's common knowledge that is the most commonly cited example of the use of in situ firearms by militia. Maybe you're inviting a debate on why you think the reports on in situ firearms reported there are false, or maybe you just randomly came upon that, but it doesn't seem a coincedence.
Myanmar/Burma the strategy was build-to-capture: make improvised, unreliable firearms that could be used to ambush security forces and take their firearms.
Evidence against the point above that it's trivial to replace professionally manufactured small arms.
