It is my understanding that Pine Tree Castings (Ruger) casts MRC actions. I'm sure MRC takes it from there with final machining, fitting, etc. No one questions the strength and quality of Ruger firearms.

And MRC adds a gas blocking device in the left raceway, addressing an issue occasionally raised with the M-70 design.

I don't own a MRC rifle, have never shot one. I'd for sure take a Pre-64 over an MRC, if given the choice... smile

Would probably take a CRF M-70 with New Haven trigger over a MRC.
