WMD Guns AR Upgrades

WMD Guns is one of the leading manufacturers of high-performance coatings, and all WMD Guns AR parts are made in the United States. If you are finishing an AR-15 building project and want an upper receiver with better durability than a chrome-based product, take a look at our selection of WMD upper receivers. The upper receiver has a NiB-X coating, which boasts a surface with a hardness rating of Rc70. The slick surface makes cleaning easier, and it is more resistant to corrosion.

We also sell a wide variety of smaller individual WMD Guns AR-15 upgrades that are coated with NiB-X. There are M16 bolt carrier groups, buffer tubes, charging handles, safety selectors, gas blocks and more. These WMD Guns accessories are perfect for any new building project or for your replacement needs. The enhanced surface of a part with a NiB-X coating yields smoother action when multiple metal components touch or move. Shop today and get your order shipped quickly via our live inventory system!
