Ballistic Advantage 16″ 5.56 Government Profile Midlength AR-15 Barrel Modern Series w/ FSB Circular Handguard Cap

The Ballistic Advantage 16″ 5.56 NATO Government Profile Barrel from the Modern Series brings together classic mil-spec styling with upgraded performance. Precision-machined from 4150 Chrome Moly Vanadium steel and treated with a QPQ nitride finish, this barrel offers long-lasting corrosion resistance and smoother bore life.

Equipped with a pre-installed front sight base (FSB) and circular handguard cap, it’s ideal for builders looking to replicate a classic A2-style upper or modernize a retro build. The 1:7 twist rate stabilizes a wide range of 5.56 loads, while the mid-length gas system ensures smooth cycling and reduced recoil over carbine-length setups.

With a .750 gas block journal, M4 feed ramps, and standard 1/2×28 muzzle threads, this barrel is ready to drop into any quality AR-15 build that calls for reliability and performance without compromise.
