Secondly, to push the original post a bit further down the pike, are these MIM parts a serious issue and should these parts be replaced before the weapon malfunctions when you need it most?

Metal Injection Molding.

Eg, parts made in a mold, and not cut from bar stock.

I thought that MIM was more of a sintering type process, where the metal is put into a mold in powdered form and then heated until it fuses. Molding liquid metal is casting, and casting is not necessarily bad. I once bought a set of cast 1mm overbore pistons from Yoshimura for my race bike, and they performed just fine, spinning at 11,500 rpm for hundreds of miles. It's hard to imagine a tougher environment than that.

Seriously, I don't know how to tell just from its looks.

You stole my line!
