Custom made from factory parts, This is the Mk18 Mod1 from Daniel Defense, without BCG and charging handle.
Nowhere else, but at Charlie’s does the Daniel Defense Mk18 Upper Receiver clone 10.3″ URG get the respect it deserves. Daniel Defense has held true to the design of the Mk18 rail, the 9-1/2″ RIS rail, in FDE, which was the original Mk18 rail. Daniel Defense now provides us with a reasonable representation of the original Mk18 upper, with a few commercial licenses, that allow Daniel Defense and Charlie’s Custom Clones to offer this Mk18 upper at a reasonable price, and you add the charging handle and BCG of your choice.
The Daniel Defense MK18 Complete AR-15 Upper Assembly is a faithful recreation of the US Navy’s Mk18 Mod 1 platform, and features a Premium 10.3″ Cold Hammer Forged Barrel made from Mil-Spec 4150 Chrome-Moly Vanadium Steel; Chrome Lined for durability and corrosion resistance. M4 feed ramps are incorporated into the barrel extension and upper to enhance reliable feeding, while a true 5.56mm NATO chamber ensures that both commercial and higher pressure surplus mil-spec ammunition may be safely used.
The upper receiver is made by Daniel Defense with solid forged aluminum and Type III Hard Coat Anodized.
This upper comes equipped with a 9.5″ Flat Dark Earth (FDE) RIS II Mk18 Quad-Rail Handguard that covers a pinned, low profile gas block at the carbine gas port position and Free Floats the barrel for increased accuracy potential. The RIS II provides ample room for adding tactical accessories, while also creating a full length, uninterrupted top rail surface with the A4 Flat-Top receiver that can accommodate a shooter’s chosen optic and/or iron sight arrangement. Complete with Daniel Defense Flash Hider, the MK18 upper is ready to drop onto any pistol or registered SBR small pin lower receiver, after you add your M16 or AR15 bolt carrier group and charging handle
This item is custom configured by Charlie’s from 100% factory parts. Normally, Daniel Defense will send an uppper receiver with barrel and rail configured. We have found that many customers like to customize thier upper, or do not like the factory “billboard” markings that Daniel Defense ships with their factory Mk18, so this gives you options. We also give options to fit different budgets. As such, this product does not ship in a Daniel Defense factory box. We offer the factory configuration, see the next paragraph.
Charlie’s also offers what is often called the “billboard’ Mk18 upper receiver group. This is the factory Mk18 receiver with the Mk18 RIS rail. It is a little more commercal. Some like it. The Mk18 Daniel Defense FDE Factory Upper Receiver Group
