The WMD Guns NiB-X Carbine Buffer Tube is a six-position receiver extension for AR-15 and M16-pattern rifles using a carbine-length recoil system. Its 7075 aluminum construction provides a strong, lightweight foundation for compatible adjustable stocks, while WMD’s NiB-X coating adds a slick, wear-resistant surface to the exterior and stock interface.
Note: Designed for mil-spec-diameter carbine stocks and carbine-length buffer components. It is not a rifle-length receiver extension.
