Genuine HAUS barrel nut.
Material: Hardened steel.
Finish: DLC (Diamond-Like Carbon) / PVD (Physical Vapor Deposition)
DLC creates a very thin, very hard protective layer on the surface of the barrel nut, for example, a brand new MR556 barrel nut will show signs of wear the first time the handguard is removed, after several times it will show significant wear. Since these barrel nuts have been treated with DLC, any signs of wear will be significantly reduced, as a result your barrel nut will look “new” significantly longer.
Physical Vapor Deposition (PVD) or DLC coatings are applied to improve resistance to everyday wear and tear. The coating properties improve the overall hardness of the material and its ability to withstand higher temperatures. Additionally, these coatings provide resistance to corrosion along with improving the lifespan of your weapon.

* Apply oil (not grease) to the outside of the barrel nut prior to installation for best results / ease of installation.
* Apply febi grease or another high temperature grease to the threads of the barrel nut and upper receiver prior to installation to prevent galling during installation, this will also help prevent seizing in the case that the upper assembly is ever disassembled.
