The Freedom Ordnance FM-9D Complete Upper Receiver brings belt-fed 9×19 NATO performance to any compatible mil-spec AR-15 or M-16 lower without requiring modifications. This 8" button-rifled, QPQ nitride barrel features a 1:10 twist and 1/2×28 threaded muzzle capped with an A2 flash hider, while the Flat Dark Earth anodized finish and low-profile M-LOK handguard create a compact, modern upper ready for lights, grips, and other accessories. The closed-bolt blowback system feeds from a disintegrating-link belt and can instantly transition to Glock-pattern magazines when desired.

This FM-9D upper is ideal for high-volume range sessions, training, and enthusiasts who want a distinctive belt-fed 9mm setup without investing in a dedicated belt-fed lower. Its one-handed bolt charging and hold-open assist device supports fast, intuitive handling, and the included 150 reusable links, 100-round belt bag, Magblock, and soft case make it a complete upper-only package. Freedom Ordnance’s focus on durable materials, thoughtful engineering, and innovative belt-feed design is evident throughout this upper receiver assembly.
