If you take a printer like a Prusa though all the proper calibrations you can hold .005"-.0075" in most dimensions. Plenty good for 90% of machining applications. Straight walls will be inherently more precise than radiuses, shorter parts are more accurate than taller ones, etc.Well, this is interesting. What kind of dimensional tolerances do you get with those 3D printed parts? Or would you print them and then grind/mill them to size since the plastic is so soft?
When I need something to be more accurate than that, I just face it off critical surfaces with an endmill or in the lathe.
You could certainly use a 3d printed part as a sheet metal form and a router jig to do a receiver. I'd trust a 3d printed jig or fixture to do a huge majority of operations on something like an AK.
