The Sons of Liberty Gun Works SOLGW BS L89 URG 14.5" .223 Wylde upper brings the Broadsword-89 concept to life, pairing a precision 14.5" SPR barrel with the ultra-rigid L89 handguard system. Built around traditional two-piece AR-15 construction, this upper is engineered for shooters who want a match-grade feel from a dependable working rifle.

This upper receiver group uses an extended barrel nut, Drivelock tensioning crossbolts, and a keyed upper receiver face that locks into the 13.75" L89 rail. Anti-rotation tabs and a stainless steel center index dowel help maintain alignment for consistent accuracy. With 5/8x24 barrel threads and no included muzzle device, it is ready for the shooter’s preferred brake, compensator, or suppressor mount. It is an excellent choice for training, range work, or building a precision-oriented AR, backed by Sons of Liberty Gun Works’ reputation for hard-use reliability and thoughtful engineering.
