I was lucky enough to snag both BCM and WMD nib-x bolt carrier groups for my stag/AO build. I was thinking of keeping the BCM and selling the WMD because, well, it's BCM afterall. But I think I could sell the BCM for a little more and I do like the sound of the nickel boron coating on the WMD. I'm torn! I'd love to get some opinions on the subject. Especially if anyone else has experience with a WMD bcg!
