This is in the context of firearms, which are presumably modern repeating firearms, where they will cease to function if the tolerances are wrong.

You can get remarkably far with pretty crude tolerances, especially with lower pressure, pistol rounds. For example a direct-blowback, open-bolt submachine guns akin to what was used in WW2 can be pretty easily designed and built by anybody with a passable understanding of mechanics.

Again, we're talking about casting. Take a look at an Owen or a Sten and get back to me on what parts you think can be plausibly lost-PLA casted.
