Sons of Liberty Gun Works Broadsword L89 Barreled AR-15 Upper Receiver - .223 Wylde - 14.5" - No Muzzle Device

Overview

The Sons of Liberty Gun Works Broadsword L89 Barreled AR-15 Upper Receiver is a 14.5-inch precision platform chambered in .223 Wylde. It pairs a 416 stainless steel Liberty Fighting Barrel in an SPR profile with a 1:7 twist and a mid-length gas system featuring a .750-inch gas block journal. The upper is built around a billet Broadsword receiver, offering tighter machining tolerances and a more consistent barrel extension fit than standard forged uppers. The assembly features a 13.75-inch seven-sided L89 Drivelock M-LOK handguard that utilizes an extended barrel nut, tensioning crossbolts, a keyed receiver face, anti-rotation tabs, and a stainless center index dowel to eliminate micro-movement under load. The muzzle ships bare-threaded with no muzzle device installed, and the bolt carrier group and charging handle are not included.
