Do you notice any difference at all in function with the NiB? I'm also trying to decide if this is on my "want list" for the next go-round. If it will run better in instances where you may not have time/access to cleaning procedures I can see a benefit there.I've never noticed any beading. I apply M-Pro7 lube to my nickel boron bcg's the same as I would if it were phosphate. I shoot suppressed so the ability to easily clean my bcg is a must. I have 2 from WMD and 2 from Ice Arms. I know both companies properly go about the nickel boron process. I was tempted to purchase one from PSA but they ignored multiple requests on their industry page as to how they go about the process. That didn't give me any reassurance so I paid more and bought from WMD.
