Ballistic Advantage 9MM Modern Series 5.5 Straight Barrel is machined from 4150 Chrome Moly Vanadium (CMV) steel with a QPQ (Salt Bath Nitride) Corrosion Resistant Finish; The M4 extensions are also QPQ coated. Ballistic Advantage coats their extensions and barrels separately to ensure long lasting torque values. This Modern Series 5.5 Straight Barrel is configured with a blowback gas system (no gas block or tube required), and includes a sub MOA accuracy guarantee from BA. What more could you ask for from a barrel with this much value?
- 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.
- 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.
