Sons of Liberty Gun Works Broadsword L89 Barreled AR-15 Upper Receiver - .223 Wylde - 14.5" P/W - Plan B

The Sons of Liberty Gun Works Broadsword L89 Barreled AR-15 Upper Receiver in .223 Wylde pairs a 14.5" Liberty Fighting Barrel with SOLGW's billet Broadsword upper receiver and L89 Drivelock M-LOK rail, a precision-oriented platform built on the tightest upper-to-handguard interface SOLGW offers.

Features:

• 14.5" 416 stainless steel barrel, SPR profile, 1:7 twist
• .223 Wylde chamber
• Mid-length gas system, .750" gas block journal
• Billet Broadsword upper receiver for tighter tolerances than forging
• 13.75" L89 Drivelock M-LOK handguard, seven-sided
• Extended barrel nut, tensioning crossbolts, keyed receiver face, anti-rotation tabs, and stainless center index dowel
• Muzzle ships with a Plan B flash hider pinned and welded to bring the assembly to a legal 16" overall length
• Bolt carrier group and charging handle not included

The billet Broadsword upper's tighter machining tolerances give a more consistent barrel extension fit and upper-to-lower interface than a standard forged upper, and the L89 Drivelock rail's extended barrel nut, crossbolts, keyed face, and center index dowel work together as three independent retention points — minimizing the micro-movement at the handguard interface that causes point-of-impact shift under load, especially with a rail-mounted laser or VAS system.

Sons of Liberty Gun Works builds and test-fires every rifle and barreled upper in the United States, applying the same standards to individual components as they do to their complete rifles.
