Details

The Daniel Defense 18” 5.56mmNATO S2W® barrel is designed with a heavy strength to weight profile and a Mid-length gas system.

Cold Hammer Forging of barrels has been known for decades to produce the most accurate, longest lasting rifle barrels obtainable. The Cold Hammer Forging of barrels is accomplished through intense hydraulic pressure applied at opposing angles by carbide steel hammers. During the hammering process, a mandrel is inserted into the bore while the carbide steel hammers shape the barrel around the mandrel creating the chamber, the lands, and the grooves. In addition to the aforementioned benefits, the Cold Hammer Forging process creates a defect free bore and the most consistent chamber possible.

Stripped Barrel  2.65lbs 
 Barrel w/ LPG 2.73lbs 


All Daniel Defense cold hammer forged barrels are made from start to finish in our state-of-the-art facility located in Black Creek, GA. In keeping with our heritage of not cutting corners, all cold hammer forged barrels feature a forged chamber and highest quality exterior coating. These barrels will prove themselves to be more accurate and last longer than a barrel that has cut or button rifling.

    This barrel is a tack driver. I’m running one cut to 14.5 with a pinned brake. Obviously not the lightest option out there but it’s simply a fantastically robust and stable platform and extremely accurate.

    Have this on my hunting/dmr rifle. Shoots exceptionally well with any ammo I run.(55-77gr)
    Doesn't make for the lightest rifle but that is not what it was designed for.

    Used this outstanding barrel on my scratch-built M4. Paired it with an Adam Arms piston. The result is my M4 easily shoots sub-MOA ... a real tack driver!

    I put this barrel on my first build because i knew of Daniel Defense quality and wanted an 18" mid length gun. Though it is a little heavy it shoots exceptionally well with any ammo. Weight, well in my eyes an 18" gun is an AR built for a little more Distance and not close quarters. So, I went generally light with everything else and its an awesome build. I tried the Daniel Defense stock, grip, for-grip package as well which i like as well.

    Bought this barrel and used your 15" Slim rail and clamp style low profile gas block on a BCM upper receiver and Spike's Lower using your Lower receiver parts kit and Tornado Furniture. Your team is producing some quality stuff...

    Used this barrel on my third build. Worked perfectly with a Founding Fathers billet lower and Seekins Precision billet upper. Rifle is extremely tight, solid and accurate. It was a little spendy but turned out to be worth the money.
