Ballistic Advantage 5.5" 9MM Modern EPC Series AR-15 Barrel 1:10 Twist - $49.95

Description

Upgrade your AR9 build with the Ballistic Advantage 5.5″ 9MM Modern EPC Series Barrel, engineered for maximum reliability in compact platforms. Made from 4150 CMV steel and treated with a QPQ corrosion-resistant finish, this barrel delivers both long-lasting durability and smooth operation.
The 1:10 twist rate ensures reliable stabilization across a wide range of 9mm projectiles, while the integrated feed ramp promotes consistent cycling. Designed to work with Colt/RR and Glock-style magazine builds, the EPC barrel is optimized for blowback systems and fits standard AR-15 uppers or dedicated 9mm receivers.
Its compact size makes it ideal for PDW builds, suppressed applications, or close-quarters setups—while the 1/2×28 thread pitch offers greater compatibility with common 9mm-rated muzzle devices and suppressors.
