The Sons Of Liberty Gun Works Liberty Fighting Barrel 14.5" 5.56 Chrome Lined is built for shooters who want a hard‑use AR‑15 barrel with dependable accuracy. Crafted from 41V50 chrome moly steel with a phosphate exterior and chrome‑lined bore, this medium contour, threaded barrel uses a .223 Wylde chamber, 5R rifling, and a 1:7 twist to balance precision, longevity, and versatility with both .223 Remington and 5.56 NATO ammunition.

This 14.5" mid‑length gas barrel is well suited for general range use, training, and duty‑style builds where smooth cycling and manageable recoil are important. The .750" gas journal with a deep dimple simplifies secure gas block installation, while standard 1/2x28 threads accept a wide variety of muzzle devices. It’s a practical upgrade for anyone assembling a reliable AR‑15, backed by Sons Of Liberty Gun Works’ reputation for thoughtful design and robust craftsmanship.
