NiB-X AR-15 A3/A4 UPPER RECEIVER

Whether you are looking to upgrade your MSR or starting a fresh build, WMD Guns has the parts to make it happen. This WMD Guns NiB-X A3 | A4 Upper Receiver is a great place to start. This 7075 T6 Aluminum forged Mil Spec stripped receiver with M4 feed ramps has NiB-X coating inside and out to provide an exceptionally tough, ultra-smooth surface finish for outstanding wear resistance and lubricity. NiB-X is almost twice as hard as anodize and has a much lower coefficient of friction. Topcoated on the outside only with a black ceramic coating leaving NiB-X exposed on the inside wear surfaces. Standard colors available are Black, Flat Dark Earth or OD Green. Other colors upon request. A matching Flat Dark Earth NiB-X charging handle is a perfect compliment for this upper receiver.
