Basically you need to wipe it down at the end of every shooting day. Sure something that should be done regardless, but doesn't match how these are usually marketed. And not always something that happens when talking about a worn out, end of 16 hour patrol, grunt.
There are maybe three coatings I'd consider. Microslick from Cerakote, NP3 or NP3+, and maybe hard chroming.
I am gonna make a guess on this say maybe the issue is if the BCG was designed from the ground up to be NiB or not....in other words, a milspec carrier with the added thickness of a coating is more likely to be stuck than one that was engineered with that in mind.
