The OP swapped his mates BCG for his and still got light primer strikes. Fair to assume the OP's gun functions OK. His BCG works in his gun, but not his mates. This is why I think it's more to do with either the chamber reamed too long, or the ammo is too short, and the BCG is OK.
Another poster mentioned the difference in some Grendel bolts so I was just trying to provide information I had saved in regards to different products on the market. I think the OP can sort out the issue given enough time. It sounds like a chamber/head space issue but hard to say without having the upper to inspect.
