Ballistic Advantage Modern Series 5.56 Barrel Gov. Carbine – 11.5″
Compact, reliable, and built to perform under pressure.
The Ballistic Advantage Modern Series 11.5″ 5.56 NATO Barrel is purpose-built for AR-15 pistol and SBR builds that demand reliability and durability in compact configurations. Machined from 4150 Chrome Moly Vanadium steel and treated with a QPQ salt bath nitride finish, this barrel offers long-lasting corrosion resistance and consistent performance under sustained use.
Its government profile keeps weight manageable while maintaining strength, and the carbine-length gas system ensures smooth cycling—especially with common 62-grain loads, which pair perfectly with the 1:7 twist rate. Finished with M4 feed ramps and a 1/2×28 threaded muzzle, it’s compatible with all standard 5.56 muzzle devices and suppressors.
Whether you’re building for home defense, duty use, or training, this barrel delivers the performance and precision Ballistic Advantage is known for.
