Ballistic Advantage 5.5″ 9MM AR 15 Barrel, Modern Series

Description

Introducing the Ballistic Advantage 9mm chambered 5.5-inch Modern Series Barrel, a true masterpiece in firearm engineering. Crafted from robust 4150 Chrome Moly Vanadium steel, this barrel features a QPQ Corrosion Resistant Finish and 1/2-28 x .400 full profile threads for enhanced performance.

Key Features:

Versatile Compatibility: Designed to work seamlessly with both Colt/RR and Glock style AR builds, making it a versatile choice for your firearm.

Multiple Upper Options: Compatible with standard mil-spec uppers, and there are numerous dedicated 9mm upper options that work flawlessly with this barrel.

Magwell Requirements: Requires the use of a unique magwell conversion (Colt/Rock River style) with UZI mags or a dedicated 9mm lower with Glock mags.

Gas-Free Operation: Operates on a blowback system, eliminating the need for a gas block or gas tube.

Suppressor-Friendly: Threaded 1/2×28 instead of 1/2×36, giving you greater versatility when choosing a suppressor for your setup.

Integrated Feed Ramp: Equipped with an integrated feed ramp and barrel extension for smooth and reliable feeding.

True Length: The stated length accounts for the integral barrel extension, ensuring you get the true overall length. For example, an 11 9mm barrel has the same outer dimensions/length as a 10.5 5.56 barrel.

Critical Note: Standard 1/2×28 flash hiders may not provide sufficient clearance for a 9mm round. Always ensure that a 9mm round drops freely through the muzzle device bore before installation.
