I use Chinese contract CNC providers for non-firearm parts all the time: you're sorely mistaken if you think any random Chinese millshop can't produce a 100-year-old design just as well as any American one.
They can't produce those designs or even gun parts without risking the death penalty, so no private business will go near them, and they definitely won't specialize in it.

Once. They do it once, then there is a huge death penalty trial that is rehashed on CCTV for weeks. You definitely won't get any scale out of it, no one will invest in something that will get them executed, so definitely nothing near to what the Americans can produce as the world's most economical gun producers.
These days, it feels like America basically sucks at making anything besides guns. For guns, no one else really compares, and if it weren't for the Darien Gap the whole of the Americas would be overflowing with guns from the USA (also, Brazil also makes lots of guns, meaning the production is roughly divided between the USA in the north and Brazil in the south).
