This 9mm chambered 8.3 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 1/2×28 instead of 1/2×36 to give you greater versatility when choosing a suppressor.
Integrated feed ramp and barrel extension.
Since the â€œbarrel extensionâ€ is an integral part of the barrel, the length stated is the true overall length. For example, an 11â€ 9mm barrel has the same outer dimensions/length as a 10.5â€ 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.
