The Daniel Defense 5.56 NATO 10.3" 1:7" CMV CHF Carbine‑length Gov’t Barrel Assembly is a short, rugged barrel built for compact AR‑platform pistols and SBRs - cold‑hammer‑forged from 4150‑series CMV steel for long life and consistent accuracy, with a 1:7" twist optimized for stabilizing heavier 5.56/.223 projectiles. At a nominal 10.3" overall and weighing roughly 1.25lbs including a typical gas block and muzzle device, it offers a gov’t‑profile balance of stiffness and controllable weight for agile handling. The barrel normally ships with standard carbine gas spacing, common muzzle threading (1/2"‑28 TPI), and a surface treatment (chrome‑lined or nitride depending on production lot) for wear and corrosion resistance. Designed to mate with standard AR‑15 upper receivers and handguards, it’s a straightforward drop‑in choice when you need a compact, durable barrel that maintains reliable function with a wide range of 5.56 ammunition.
