Im Positive the FSB isn't leaking and you all say the tubes are the same, springs are the same, so the BCG is the difference.
Both BCG's are basically new and bolts and rings are too. And the staking and key are not moving or blocked, Mia-aligned
It's possible that the new BCG just needs a little breaking in, which can be accomplished by running a few hundred rounds of good 5.56mm ammo through it. Do you notice any more resistance when moving the bolt in the new BCG? I have found that some of my uppers become more ammo tolerant over time as the parts break in.
