The WMD Guns Nib-X bolt carrier group itself is excellent. The low friction is noticeable and definitely helps with smoother cycling. I've been running it in a 5.56 build and performance is consistent. My only minor gripe is the included hammer. It does the job, but I ended up swapping it for a different brand to get the trigger pull I prefer. Still, a very solid BCG.
Got this WMD Nib-X BCG for my new build, running a rifle gas system. The Nickel Boron finish is legit, super slick. After a few hundred rounds, carbon just wipes right off. Cycles perfectly, no hiccups whatsoever with 5.56 NATO. This M16 carrier is rock solid.
