Sons of Liberty Gun Works AR-15 L89 Broadsword Barreled Upper Receiver 223 Wylde 14.5"

The Sons of Liberty Gun Works Broadsword-89 Uppers and Drivelock (89 Series) rails provide arguably the most rigid interface on the market using traditional 2-piece AR15 construction. The extended barrel nut, Drivelock tensioning crossbolts, and keyed upper receiver face hugging the 89 series rails, with their anti-rotation tabs and stainless steel center index dowel allow you to turn almost any lower receiver into match grade rifle. While the Billet Broadsword upper receivers are purpose built for precision, they still retain compatibility with standard dimension milspec contour lower receivers.These 3 groove polygonal rifled 416 Stainless barrels have been turning heads since their release, offering true sub-MOA small frame gas gun performance, at an industry leading value. SOLGW even used 5/8" x24 thread on these barrels to maximize their precision, and made purpose built muzzle devices to take advantage of this. Note: Uppers with a muzzle device installed are pinned and welded
