Came across this thread on the Custom Rifles and Wildcats subforum:

The subject of getting the last of the salts out of the receiver/barrel interface comes up and there is discussion about whether to remove the barrel from the receiver. I specifically asked H&M about this and was told that I needn't remove the barrel from the receiver. I'm guessing they came up with a way to get all of the residue out of the barrel/receiver threads? Or maybe I need to call them about it?
