This 9mm chambered 5.5 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 instead of 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.

This was used in PSA build, that would not present my flat point subs at the correct angle. You can see on the first pic where rounds would impact the barrel. In the description it clearly states for use in Colt/RR and Glock style builds. When run suppressed, the bolt slap was not acceptable for me. With that being said, I am hoping someone down the road can get some use out of it. I'll let this run for several weeks and then pick a name randomly.
