The Ballistic Advantage 16-inch 5.56 NATO HBAR Mid-Length Barrel (brand part no. BABL556017M) is machined from CrMoV steel and finished with a QPQ corrosion-resistant coating for long-term durability. Part of Ballistic Advantage’s Modern Series lineup, this barrel uses a heavy-profile HBAR contour that adds forward weight for a steadier hold and helps manage heat during extended strings of fire. The M4 feed ramp extension is also QPQ coated to match the barrel’s corrosion resistance, and the barrel carries a laser-engraved HBAR marking. The mid-length gas system gives a smoother cycling impulse than a standard carbine-length setup on a 16-inch barrel.
