This 9mm AR-15 barrel is designed for blowback 9mm AR builds and is finished in a QPQ corrosion resistant coating. It features integrated feed ramps and a barrel extension, with 1/2-28 x .400 full-profile threads. This 5.5 inch Modern Series barrel is compatible with Colt/RR and Glock style AR configurations and standard mil-spec uppers. It requires a magwell conversion for UZI mags or a dedicated 9mm lower with Glock mags. Because it operates on a blowback system, a gas block or gas tube is not required. Threaded 1/2x28 to accommodate various muzzle devices. Important: ensure proper clearance for certain flash hiders. You may use this barrel with a lower receiver that is a Registered SBR, Machine Gun, or Pistol; possession with a Non-NFA lower is prohibited unless installed on a pistol configuration firearm.
