Details
The Sons of Liberty Gun Works Broadsword L89A in .223 Wylde with an 18-inch barrel is the longest option in the L89A lineup, pairing a rifle-length gas system with the ARCA-equipped DriveLock handguard for a precision-oriented upper receiver. It ships without a muzzle device installed.
This is a barreled upper receiver only. It does not include a bolt carrier group or charging handle — both must be sourced separately to complete the upper assembly.
The 18-inch 416 stainless steel barrel features an SPR profile, a 1-in-7 twist rate, a .223 Wylde chamber, and a rifle-length gas system with a .750-inch gas block journal. The muzzle is threaded 5/8x24. The Broadsword-89 billet upper and L89A DriveLock rail use an extended barrel nut, tensioning crossbolts, a keyed receiver face, anti-rotation tabs, and a stainless steel center index dowel for a rigid interface.
The L89A handguard features integrated ARCA with RRS-Lock compatibility, a titanium barrel nut, 7-sided M-LOK, and integral steel QD cups. Handguard length is 16.75 inches. The Broadsword-89 upper is compatible with standard milspec contour lower receivers.
The rifle-length gas system provides the softest recoil impulse and smoothest cycling in the Broadsword lineup, reducing bolt carrier velocity for improved consistency and component longevity.
The 18-inch barrel maximizes velocity from the .223 Wylde chamber and is well suited for precision rifle builds, competition, and applications where ballistic performance at range is the primary objective.
