The WMD Guns Upper Assembly in 16" 300 AAC Blackout combines forged AR-15 precision with advanced coatings to deliver reliable performance and long-lasting durability. Crafted with hardcoat black anodized aluminum, this complete upper features a NiB-X coated charging handle, bolt carrier group, and handguard for smooth operation and easy maintenance, while the Nitromet treated gas tube, low-profile gas block, ejection port cover, and forward assist ensure consistent cycling and control across a range of conditions. The package includes a muzzle brake to manage recoil and maintain accuracy during rapid fire, making it a capable foundation for builds that demand both strength and finesse. Designed for complete upper receiver assemblies, this unit aligns with the 16" barrel and 300 AAC Blackout specifications to optimize performance for subssonic or supersonic loads, depending on your needs. WMD Guns draws on a team of metallurgists, chemists, gunsmiths, and plating engineers to produce in-house, high-precision components, and this upper assembly reflects that expertise through thoughtful integration, reliable fit, and a professional finish ideal for hunting, range work, and tactical applications.
