Daniel Defense Brl Assembly Cmv Chf 5.56 10.3" Gov'T Carbine Length Wlpg

The Daniel Defense 5.56 barrel assembly delivers the reliability and precision AR builders demand in a compact 10.3-inch platform. Built from 4150 Chrome Moly Vanadium steel via cold hammer forging, this government-profile barrel is engineered for the hard use and longevity serious shooters expect from Daniel Defense. Whether you're building a short-range carbine, a home-defense AR, or a truck gun that needs to earn its keep, this barrel combines proven metallurgy with mil-spec durability that won't quit.

The barrel comes with a carbine-length gas system, making it a straightforward drop-in for standard AR builds. The heavy phosphate coating and chrome lining protect against corrosion while handling full-power loads and rapid fire without compromise. At 10.3 inches, you get a balance of velocity and manageability—short enough to be fast and handy, long enough to wring solid performance from 5.56 ammunition.

Daniel Defense barrels are known for holding tight tolerances and running clean. This one's no exception. If you're upgrading an existing build or starting from scratch, a factory DDM4 barrel assembly takes the guesswork out of component matching and lets you focus on what matters: a rifle that works when it counts.

Specifications

Frequently Asked Questions

Will this barrel assembly fit a standard AR-15 build?

Yes. The government profile and carbine-length gas system are standard AR-15 specifications, so this barrel assembly integrates with common upper receivers and bolt carriers.

What's the advantage of a 10.3-inch barrel for a 5.56?

A 10.3-inch barrel keeps the rifle compact and maneuverable while still delivering usable velocity and energy. It's a practical choice for home defense, vehicle storage, and close-to-medium-range shooting.

Why is this barrel chrome lined?

Chrome lining reduces fouling, improves corrosion resistance, and extends barrel life under sustained use. Combined with the phosphate finish, it provides robust protection for field conditions.

Is this a complete upper assembly or just the barrel?

This is a barrel assembly. You'll need to pair it with a receiver extension, gas tube, bolt carrier group, and charging handle to complete an upper receiver.
