This is a barrel "kit," so it comes with a DD low profile gas block semi-permanently attached (pinned) or set screws attached, gas tube attached and DD RIS barrel nut.
Note: This is the correct barrel profile for an M4A1 Block 2 build, as the gas system needs to be carbine length for the gas block to fit correctly under the Daniel Defense RIS rail assembly.
Also included is premium Daniel Defense extended flash hider, which has been pinned and welded at the factory, putting the overall barrel length over 16" and thus not a short barrel requiring NFA registration.
So, this is ready to go, to insert into your upper receiver and attach your DD RIS rail. If, you don't want to use a Daniel Defense RIS rail, you can remove the barrel nut by taking the gas block off, and you can then use a Geissele rail, or whatever rail your heart desires.
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.
