Aero Precision 5.5" 9MM CMV Barrel

Aero Precision 5.5″ 9MM CMV Barrel

Compact & Reliable for Your AR9/PCC/EPC Build

The Aero Precision 5.5″ 9MM CMV Barrel is engineered for performance and reliability in AR9, Pistol Caliber Carbine (PCC), and EPC builds. Machined to mil-spec standards from 4150 Chrome Moly Vanadium (CrMoV) steel and finished with a QPQ corrosion-resistant coating, this barrel provides the durability and accuracy required for high-performance 9mm firearms.

Key Features

• Caliber: 9mm
• Length: 5.5 inches
• Material: 4150 CrMoV Steel – Ensures strength and longevity.
• Finish: QPQ (Quench Polish Quench) for superior corrosion resistance.
• Designed for Glock-Style AR Builds – Works seamlessly with EPC platforms.
• Compatible with Most Hollow Point Bullet Designs – Ensures versatility in ammunition selection.
• Works with EPC Upper Receivers & Mil-Spec Upper Receivers – Provides broad compatibility.
• Blowback Operation: 9mm AR platforms do not require a gas block or gas tube.
• Threaded 1/2×28 – Allows flexibility when choosing a muzzle device.
• Integrated Barrel Extension – Ensures accurate length measurement, meaning a 5.5″ 9mm barrel has the same external dimensions as a 5.5″ 5.56 barrel.

Important Notes:

• Standard 1/2×28 flash hiders may not have enough clearance for a 9mm round to pass through. Always verify that a 9mm round will drop freely through your selected muzzle device before installation.
• Winchester hollow point designs may result in poor feeding performance.

Optimized for Compact AR9 & PCC Performance

With its short 5.5″ length, durable construction, and compatibility with Glock-style magazines and EPC receivers, the Aero Precision 5.5″ 9MM CMV Barrel is the perfect foundation for a compact, reliable, and high-performance PCC build.

NOTE: As of 1 April 2024, all Aero Precision barrels will be marked as manufactured by Ballistic Advantage and will include the Ballistic Advantage engraving. For more information, please click here.
