The Daniel Defense 5.56 NATO 16" 1:7" CMV CHF Mid‑Length Gov’t Barrel Assembly w/ FSB is a service‑grade, cold‑hammer‑forged 4150 CMV barrel cut to mid‑length gas spacing and fitted with a rugged fixed front sight. At 16" with a 1:7" twist and standard 1/2"‑28 muzzle threads, it’s built for reliable cycling and stabilizing heavier 5.56/.223 projectiles. The barrel’s corrected nominal weight (including the FSB and a low‑profile gas block) is 1.81 lbs, and it typically ships with a wear‑resistant bore/chamber treatment (chrome or nitride depending on production lot), making it a durable drop‑in option for mid‑length AR builds.
