This  Ballistic Advantage 9mm chambered 11 inch Barrel is machined from 4140 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and 1/2-28 threads.

  • Designed to work with both Colt/RR and Glock style AR builds.
  • Compatible with standard mil-spec uppers. There are also numerous dedicated 9mm upper options that work.
  • Requires the use of a unique magwell conversion (Colt/Rock River style) with UZI mags or a dedicated 9mm lower with Glock mags.
  • 9mm on an AR15 platform operates by blowback and does not need a gas block or gas tube.
  • Threaded in 1/2x28
  • 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.
  • Before installing a muzzle device, ensure a 9mm round will drop freely through the muzzle device bore.

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.
