The Novox Research XSD barrel system uses a ported 9mm AR barrel with ports just after the chamber to slow the velocity of standard supersonic ammo to subsonic levels for better suppression, just like an MP5SD. The kit includes a ported barrel, taper mount and shroud, Alpha pattern thread adapter, Bravo pattern Hub adapter, and spanner wrenches. It is NOT a suppressor and by itself does NOT reduce the sound signature of any firearm. Before someone asks, no the kit does not turn a 9mm AR into a roller delayed MP5. It just reduces the velocity of projectiles fired through it. YouTube Compliance: This video is not sponsored and does not contain paid promotions. All magazines in use hold under 30 rounds.
