Super-Shorty AR-9 Barrel for Defensive Pistols
Specialized for personal defense AR-9 builds, this barrel’s length is a mere 4.5 inches, including the barrel extension. The length is equivalent to most standard full-size handguns, so the ballistic performance is similar. That means you gain incredible handling with your AR, with a short, stiff barrel that is perfect for mounting a suppressor or flash can.
- Designed to work with both Colt/RR and Glock style AR builds.
- Straight profile barrel reduces weight and maintains high accuracy.
- 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.
- 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.
