Prior to MIM Ruger's internals were investment cast. MIM is MUCH more precise than investment casting. This crap that there's something wrong with MIM just has to stop. 20 freaking years now. Its a BETTER process than investment casting for internals, don't whine.
A lot of turbine blades are now MIM.
On the other hand, SAI made their M1A extractors MIM, and they break all the time.
First thing any thinkin' person does is swap'em out for the identical M1 rifle extractor, a lowest bidder part, that almost never breaks.
So mind your own business, Karen.
