5.56, 1:7, 10.3", GOV, CAR W/FSB

The Daniel Defense 5.56 NATO 10.3" 1:7" CMV CHF Carbine‑Length Gov’t Barrel Assembly w/ FSB is a compact, service‑oriented barrel built for short AR‑platform pistols and SBRs. Cold‑hammer‑forged from 4150‑series CMV alloy steel and heat‑treated for durability, the 10.30‑inch barrel uses a 1:7" twist to reliably stabilize heavier 5.56/.223 projectiles. It ships with a fixed front sight (FSB) integrated at the carbine gas spacing for rugged, zeroed‑for‑life iron‑sight use and typically features standard 1/2"‑28 TPI muzzle threading to accept common muzzle devices or suppressors with the appropriate adapter. Nominally weighing about 1.2–1.4 lb depending on the specific gas block and muzzle device, the barrel is offered with corrosion/wear‑resistant bore/chamber treatment (chrome or nitride depending on production lot) and is designed to drop into standard AR‑15 upper receivers and handguards for straightforward installation and dependable service in compact builds.

All of Daniel Defense’s Barrels offer high performance and a long lasting construction. All barrels are cold-hammer forged and made from 4150 Chrome Moly Vanadium steel with a mil-spec heavy phosphate coating as well as a chrome lining for superior durability. In addition, Daniel Defense Barrels are offered in a massive assortment of configurations, with options available for different lengths, gas-blocks, thread pitches, and calibers.
