9mm on an AR15 platform operates by blowback and does not need a gas block or gas tube.
Threaded 1/2×28 instead of 1/2×36 to give you greater versatility when choosing a suppressor.
Integrated feed ramp and barrel extension.
Since the ?barrel extension? is an integral part of the barrel, the length stated is the true overall length. For example, an 11? 9mm barrel has the same outer dimensions/length as a 10.5? 5.56 barrel.
IMPORTANT:?A standard 1/2×28 flash hider will not have enough clearance for a 9mm round to pass.
Before installing a muzzle device, ensure a 9mm round will drop freely through the muzzle device bore.

ALL NFA/ATF Rules Apply?- You may use this barrel with a lower receiver that is a Registered SBR, Machine Gun, or Pistol. Possession of this barrel along with a Non-NFA lower receiver is Prohibited, except when installed on a Pistol configuration firearm.
