[Ricochet]

That's not too bad, assuming that the metal is reasonable high grade and you don't see any stress cracks going through the pin hole. The next major drop or torque put on the receiver could finish it off though. The takedown and pivot pin holes are the weak spots on any receiver. There isn't a whole lot that can be done to reinforce it structurally, so I'd recommend using it until it breaks. You never know, might go for years like that.
