Details:

When you decide to build an AR-15 rifle, there are a lot of options you need to consider. The variables involved in barrel selection alone could very well be maddening. if you want a high-quality 5.56 barrel that brings a lot of value to the table, WMD Guns 16" Mid-Length 5.56 NiB-X Nickel Boron Barrel makes an awesome choice.

Manufactured and Coated for Better Performance

4150 Steel Machined Right

WMD Guns 16” 5.56 barrel is built to work in the real world. This quality 16” 5.56 barrel is pre-tapped for a mid-length gas system. The government profile 4150 steel barrel features true 5.56 NATO chambering, and 1:8 button rifling to keep your bullet in good trim as you send it down range.

Advanced Coatings

WMD uses their own advanced coating methods to produce barrels with superior surface durability and wear resistance. The NiB-X barrel features a Nitromet nitride bore. Their Nitromet treatment is superior to chrome in longevity as well as accuracy and provides a measure of self-lubricity that gives the NiB-X barrel an edge on others. Nitromet is easy to clean, wears longer and requires less additional lubricant than chrome coatings traditionally used in barrel chambers.

WMD’s proprietary nickel boron finishing process NiB-X is used on the exterior of the 5.56 barrel to provide more efficient heat dissipation and resistance to surface wear that’s difficult to find elsewhere. The WMD 16” 5.56 barrel includes a NiB-X coated barrel extension that allows for smoother operation than traditional coatings, especially when teamed with WMD’s NiB-X bolts and complete bolt carrier groups.
