Sons of Liberty Gun Works Broadsword Billet/L89A .223 Wylde Precision 16" Bbl L89A Int ARCA Rail No Muzzle Device Upper Receiver U-BS-L89A-556-16-NMD

The Sons of Liberty Gun Works Broadsword Billet/L89A Upper Receiver is a dedicated precision upper assembly that combines high-velocity performance with the enhanced utility of the L89A handguard. This model is built on the reinforced Broadsword-89 billet receiver, which features thickened walls to virtually eliminate rail flex and provide a more stable platform for long-range optics. The 16-inch 416R stainless steel precision barrel is chambered in .223 Wylde and utilizes a mid-length gas system to ensure a smooth, reliable cycle. A standout feature is the integrated ARCA rail on the bottom of the handguard, allowing for instant and rock-solid attachment to tripods—a critical benefit for precision shooters. This "No Muzzle Device" (NMD) version leaves the 5/8x24 threaded muzzle open, giving the end-user the freedom to select their preferred high-end muzzle brake or suppressor mount.
