The Sons of Liberty Gun Works Broadsword-89 223 Wylde assembled upper receiver for AR-15 delivers match-grade precision in a compact, modular platform. Chambered in .223 Wylde with a 16″ barrel featuring 1:7 twist rate, 416 stainless steel construction, and 5/8-24 muzzle threading, this upper pairs proven accuracy with practical versatility. The three-groove polygonal rifled barrel provides true sub-MOA performance across both .223 Remington and 5.56 NATO ammunition.
The BROADSWORD-89 receiver features engineering refinements that set it apart from standard uppers. The Broadsword-89 integrates with M89/L89 handguards via relief cuts on the upper receiver face, with enhanced lockup that reduces rail flex even further, minimizing point-of-impact shift during aggressive bipod and barricade loading. The extended barrel nut and Drivelock tensioning crossbolts deliver an exceptionally rigid interface, transforming any standard lower into a precision rifle.
This upper is outfitted with a 15″ M89 free-float M-LOK Drive Lock handguard providing ample space for accessories, while the patent-pending Drivelock design uses three independent wedges that interface with angular grooves in the proprietary barrel nut, clamping the rail with extreme force and precision while driving the handguard rearward towards the upper receiver. The high-efficiency NOX muzzle device reduces recoil and muzzle rise for faster follow-up shots, and is compatible with Dead Air suppressor mounts for those seeking further refinement. Perfect for competitive shooters and precision-focused AR builds demanding uncompromising performance.
