But to address your main question, most bullets are not magnetic. Some are, in which case idk how the mri would impact them. But most would fire as normal

Not a dairy farmer, used to live by some and when I've seen them using machines it's still labor intensive, they guide the cows in, clean the machines, attach the machine, make sure the cows move out once done etc, so still requires them up and working. The machine just means they aren't physicality doing the milking part

Yes.

Although to my memory it is because the first contact lead to 50% of their population being killed so now they live in violent isolation.

I could also be confusing them with other islands in the area.

People misunderstand 3d printed guns. We use mostly normal gun parts bought anywhere, but legally the pistol handle is considered the gun, and the most popular commercial ones have been plastic for decades. So 3d print that glock frame and put a glock slide on it and you've got a cheap glock (and outside of like 3 States, that's totally legal).

There's fairly large 3d printing gun communities, mostly because it's just fun to build things.

3d printed silencers are much more rare / fragile because those are illegal to make without ATF approval and silencers need to withstand heat and pressure, so the typical plastic can't withstand prolonged use.

I think they met either transportation or commuter
