The LBE AR-15 5.56 NATO Barrel in a 7.5-inch length (brand part no. BAR075P) is a cold hammer forged barrel built for pistol-length AR builds where a compact, maneuverable profile matters most. LBE Unlimited, a US manufacturer known for precise machining and durable components, cuts a 1:7 twist rate into this barrel to stabilize the full range of common 5.56/.223 bullet weights, then finishes it with a melonite coating for corrosion resistance and a long service life. It ships with a pistol-length gas system and 1/2×28 muzzle threading, matching the compact-build format this barrel length is designed for. Builders assembling a short-and-light AR pistol will find this barrel a reliable core component for that platform.
