NaimElmWMD NiB-X BCG stays clean
Reviewed on January 20, 2026Verified with Build
WMD Guns NiB-X BCG cycles cleaner than parkerized BCGs. Carbon scrapes off with a rag rather than a brush. Drop in fitment with proper headspace. Comes with the NiB-X hammer which is a nice bonus. Solid NiB upgrade BCG.
