A Look at the WMD Guns AR-15/M16 NiB-X Coated Upper Receiver

When it comes to firearms, the AR-15/M16 is one of the most popular platforms on the market. It's a lightweight, modular rifle that's perfect for a variety of uses, such as hunting, self-defense, or even competition shooting. With its versatility and customizable nature, it's no wonder why so many people love it.

However, even the most popular firearms need a little bit of help in order to stay in working order and perform at their best. One way to do this is with the WMD Guns AR-15/M16 NiB-X Coated Upper Receiver. This upper receiver is designed to provide an exceptionally tough, ultra-smooth surface finish for outstanding wear resistance and lubricity.

NiB-X Coating

The NiB-X coating from WMD Guns is a nickel boron coating that's applied both inside and out. It's designed to provide an extra layer of protection from wear and tear, while also providing a smooth surface finish so your AR-15/M16 can function more reliably. The coating is also applied with a ceramic topcoat on the exterior, so it looks great as well.

The NiB-X coating also works great with standard carriers, but it's even smoother when used with WMD Guns' own NiB-X coated bolt carriers. These carriers are available separately and help to further reduce friction between the bolt and the upper receiver.

M4 Feed Ramps

The WMD Guns AR-15/M16 NiB-X Coated Upper Receiver also features M4 feed ramps, ensuring reliable feeding every time. And the 7075 T6 aluminum construction is strong and durable, so you can be sure that your upper receiver will last for years to come.


The WMD Guns AR-15/M16 NiB-X Coated Upper Receiver is designed to fit standard AR-15/M16 lowers and accepts standard barrels and upper receiver parts. It also has .250" diameter pivot/takedown pin holes for added convenience.


When it comes to maintaining and improving your AR-15/M16, the WMD Guns AR-15/M16 NiB-X Coated Upper Receiver is an excellent choice. Its NiB-X coating offers superior wear resistance and lubricity, while its M4 feed ramps ensure reliable feeding. Plus, it's compatible with most standard parts, making it easy to install and use. All in all, it's a great way to give your AR-15/M16 a performance boost.
