Ballistic Advantage 5.5" 9MM Modern EPC Series AR-15 Barrel - BABL9MM026M

Enhance the performance of your 9mm AR15 with the Ballistic Advantage 5.5″ EPC (Enhanced Pistol Caliber) barrel.

Precision-machined from 4150 CMV steel and finished with a QPQ corrosion-resistant treatment, this barrel ensures durability and reliability. The 1:10 twist rate optimizes bullet stabilization, while the 1/2×28 threads offer compatibility with a wide range of muzzle devices, including suppressors.

Made in the USA, this barrel is a top choice for those seeking quality and performance in a compact package.

Features

• 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 1/2×28 instead of 1/2×36 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.
• Enhanced Feed Ramp

IMPORTANT: A standard 1/2×28 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.
