The Ballistic Advantage Performance Series 11.3-inch 5.56 barrel (brand part no. BABL556026FD) is a threaded AR-15 barrel on Ballistic Advantage‘s Hanson profile, built for builders who want a little more length than a 10.3-inch for the same compact footprint. It is machined from chrome moly vanadium steel with a QPQ finish, and a nickel boron coated extended M4 feed ramp extension helps feeding. A pinned low-profile gas block comes installed on the carbine-length gas system, and the 1/2×28 muzzle accepts standard muzzle devices. It suits an upper where handling matters but a few more inches of barrel are worth having.

Key Specifications

• The chamber is 5.56 NATO, the standard AR-15 cartridge, with the 11.3-inch length built for compact builds.
• Barrel length is 11.3 inches, a short, handy length that keeps the finished upper compact.
• The barrel is machined from chrome moly vanadium steel, a strong steel that holds up to hard use.
• The finish is QPQ, a corrosion-resistant treatment for the barrel exterior and bore.
• A nickel boron coated extended M4 feed ramp extension smooths feeding from the magazine.
• The contour is the BA Hanson profile, Ballistic Advantage’s proprietary barrel profile.
• Rate of twist is 1:7, which stabilizes the heavier 5.56 bullets that short barrels are often paired with.
• A pinned low-profile gas block is included, so the gas system is installed and ready to go.
• The muzzle is threaded 1/2×28, the common pattern for flash hiders, brakes and compensators.
• Each barrel is high-pressure and magnetic particle inspected, a quality check on the steel before it ships.
