The WMD Nibx Forged Matched Set Uppr/Lwr is a precision-machined AR-15 upper and lower receiver set paired with a free float handguard, all finished in WMD’s proprietary NiB-X nickel boron coating. Built from mil-spec 7075-T6 aluminum forgings and cut to true mil-spec dimensions, this matched set offers a rigid foundation with M4 feed ramps and a full-length Picatinny rail for optics and accessories.
This receiver set is ideal for shooters building a custom AR-15 for range use, training, or competition who want a durable, easy-to-clean platform with a smooth, slick operating surface. The free float handguard provides ample mounting space for lights, grips, and other accessories without contacting the barrel, helping preserve accuracy potential. WMD’s reputation for quality nickel boron finishes and careful machining makes this set a solid starting point for a reliable, long-lasting rifle build.
