Is that the sliding pipe gun? I think all you need is materials, a hack saw, and a drill. But with a machine shop, the materials list is just steel and some springs, and you can have a gun as good as any we had prior to the last century.
Even rifling can be cut with nothing more than a hardened piece of tool steel, a green sapling and a bit of time and patience to make what's called 'Scratch rifling'. Even a wooden rifling machine isn't hard to make if you want to boost production a bit.
And yes, the metal working shop I own is perfectly capable of making every piece of any firearm you might want. I have even made a black powder 2" Coehorn mortar to launch baby food jars filled with concrete 100s of yards. I know guys who have made full sized and functioning Gatling guns down to the horse-drawn trail it was mounted to. An expensive and time-consuming endeavor.
But it makes the general populace feel good and gives politicians more power.
