819747025975 This 9mm chambered 4.5 inch Modern Series Barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and 1/2-28 x .400 full profile 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 1/2x28 or 1/2x36 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 1/2x28 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. Additional Info Material: 4150 Chrome Moly Vanadium Finish: QPQ Corrosion Resistant Gas System Length: Blowback Gas Block Journal: Blowback Gas System - No Gas Block Twist Rate: 1:10 inches Muzzle: 1/2x28 Threaded

Description:

Enhance your AR-15 with the 9mm Modern Series Barrel!

This 9mm chambered 4.5 inch Modern Series Barrel from BALLISTIC ADVANTAGE is expertly machined from 4150 Chrome Moly Vanadium steel and features a QPQ Corrosion Resistant Finish. With 1/2-28 x .400 full profile threads, this barrel is designed to seamlessly integrate with both Colt/RR and Glock style AR builds.

Key Features:

  • Compatible with standard mil-spec uppers and numerous dedicated 9mm upper options.
  • Requires a unique magwell conversion (Colt/Rock River style) with UZI mags or a dedicated 9mm lower with Glock mags.
  • Operates by blowback, eliminating the need for a gas block or gas tube.
  • Threaded options of 1/2x28 or 1/2x36 for greater versatility with suppressors.
  • Integrated feed ramp and barrel extension for enhanced performance.

It’s important to note that the barrel extension is an integral part of the barrel, meaning the stated length reflects the true overall length. For instance, an 11” 9mm barrel shares the same outer dimensions as a 10.5” 5.56 barrel.

IMPORTANT: A standard 1/2x28 flash hider will not provide enough clearance for a 9mm round to pass. Before installing a muzzle device, ensure that a 9mm round can drop freely through the muzzle device bore.

This barrel can be used with a lower receiver that is a Registered SBR, Machine Gun, or Pistol. However, possession of this barrel along with a Non-NFA lower receiver is prohibited, except when installed on a Pistol configuration firearm.

  • Material: 4150 Chrome Moly Vanadium
  • Finish: QPQ Corrosion Resistant
  • Gas System Length: Blowback
  • Gas Block Journal: Blowback Gas System - No Gas Block
  • Twist Rate: 1:10 inches

Top takeaways

  1. The 9mm AR-15 Modern Series 5.5" barrel is made from 4150 Chrome Moly Vanadium steel with a QPQ corrosion-resistant finish and is designed for both Colt/RR and Glock style AR builds.
  2. It operates on a blowback system without the need for a gas block or tube and has a 1:10 twist rate with 1/2-28 threaded muzzle for suppressor compatibility.
