The problem with the M249 feed system is its tolerance. This is due to the fact that it's constructed with cheap stamped components. This is fine when the rifle is new; however, with a little wear the rifle quickly becomes increasingly sloppy. The weapon requires an incredible amount of attention and maintenance; otherwise, it's an incredible frustrating platform. To effectively employ the M249 with any reliability you have to know the weapon in your hands better than you know your own hands. The links are of little consequence here.
Stanc do you see that hole in that link. That instantly tells me that there's potential to decrease the width of that portion of the link and still maintain adequate strength. You must realize that Material Science has come light years since the 60's. I'm certain links can be made smaller and stronger at a comparable if not cheaper cost. However, there will be a substantial initial investment in tooling.
This is a relatively simple Engineering task in a very mature science. This task is no different than designing a magazine to reliably feed a new round, i.e. the Grendel. Have such magazines been designed? Yes, most work very well. Can that magazine design be improved upon? Most certainly.
