WMD’s NiB-X Nickle Boron Buffer Tube is a Great Choice for Your Next Build

The WMD NiB-X buffer tube is the perfect piece for a custom AR Build. Update your fixed sock system to an adjustable M4 style stock. The WMD Stock features six different precisely positioned notches that will allow you to set your length of pull to the optimum length for your best shooting experience. The WMD NiB-X Buffer Tube is precision machined from a raw aluminum extrusion for lightweight strength that you can count on. This carbine buffer tube is coated with WMD’s exclusive NiB-X Nickel Boron process. NiB-X is tougher than other manufacturer’s nickel boron plating because they create their solution from raw constituents and use a unique lead-free process that ensures an even distribution over surfaces. NiB-X is harder and more resistant to friction than other Nickel Boron finishes. Choose this Nickel boron buffer tube and you’ll get a quality, long service life. The exterior quality coating will allow easy adjustments while the Nickel Boron interior will feature less friction and resist fouling better than other carbine buffer tubes. The self-lubricious nature of NiB-X will reduce buffer and spring wear over the life of your system.
