This is a new Daniel Defense barrel, along with everything you need to install into a DD RIS-II Mk18 rail. Occasionally, we get these as part of a total assembly, and thus are "new take-offs", but most of the time we get the virgin barrel and then pin the gas block to the barrel. When we get busy, we use another shop as overflow, so expect some lead time, if we have in stock.
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.
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.
Important note on gas blocks: with this kit, you get what you get. Sometimes Daniel Defense will pin the gas block through the barrel, other times they will not. Mostly, we get a generic gas block that Daniel Defense provides. Sometimes, DD will ship with their Mk12 gas block. If you need a specific gas block, make note of that in the comments section in your order, and we will try to accommodate. If we do not have a specific gas block, we can remove what was sent to us, and install a different gas block, but that will involve shop time, meaning an additional cost and additional time. For this product, we are typically disassembling a new Daniel Defense upper, and bagging the barrel kit as it comes from the factory, and offering it to you. One more commentary on gas blocks: unless you are building something of historical significance, any gas block that Daniel Defense uses and attaches to their barrels is going to be rock solid, and in most cases, no need for you to even know what the gas block is, unless you are just one of those types...
Cold Hammer Forging of barrels has been known for decades to produce accurate and long-lasting rifle barrels. 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.
All Daniel Defense cold hammer forged barrels are made from start to finish in the DD state-of-the-art facility located in Black Creek, GA. In keeping with Daniel Defense's 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.
