The WMD Guns Upper Assy 300BLK 16" Barrel is a complete AR-15 upper assembly built around a match-grade 16 inch 300 AAC Blackout barrel and a 15 inch free-float M-LOK handguard. The NiB-X nickel finish extends across the upper, charging handle, bolt carrier group, and handguard, offering a smooth, easy-to-clean surface and a distinctive silver appearance. A threaded muzzle with included compensator helps manage recoil and muzzle rise while preserving accuracy.

This upper is ready to pin onto your compatible AR-15 lower, providing a dedicated 300 Blackout setup for both subsonic and supersonic loads. The free-float M-LOK handguard gives ample space for lights, grips, and other accessories without interfering with barrel harmonics, while the direct impingement gas system and MIL-SPEC components support reliable cycling. It’s well suited for range use, training, and hunting where shooters want the flexibility of 300 Blackout in a refined, coated package that reflects WMD Guns’ focus on advanced metallurgy and coating technology.
