Solgw BS L89 URG 14.5" .223 P/W HUX

The 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 all you to turn almost any lower receiver into match grade rifle.
