Ballistic Advantage 11" 9mm Modern Series Barrel - BABL9MM003M

This 9mm chambered 11 inch Modern Series Barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and 1/2-28 x .620 full profile threads.

Features:

• 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 AR-15 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.

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.
