FN | Hammer-Forged Barrel | 223 Rem | 5.56 NATO

FN's hammer‑forged barrels are manufactured from U.S.-sourced Chrome Moly Vanadium steel, cold hammer forged for genuine long‑term accuracy and barrel life, then High Pressure Tested and Magnetic Particle Inspected to the same standard FN applies to its military and law‑enforcement contract barrels. A chrome‑lined bore backs real corrosion resistance and easier cleaning over an uncoated barrel. The same barrel‑manufacturing quality FN builds its complete rifles around, available as a standalone upgrade or replacement part.
