On Sale!
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 choose your bolt carrier group.
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 bolt and carrier both pass a thorough Magnetic Particle Inspection (MPI) test for guaranteed structural integrity, and the gas key is properly staked to its mil-spec bolt carrier.
This upper has the improved fully Melonite coated bolt carrier and bolt. All steel BCG parts feature a full Melonite finish and the steel barrel features heavy mil-spec phosphate coating for superior corrosion resistance and durability, while aluminum parts are 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 charging handle assembly and Daniel Defense Flash Hider, the MK18 upper is ready to drop onto any pistol or registered SBR small pin lower receiver. .
In addition to the factory Mk18 upper receiver group from Daniel Defense, Charlies also offers the customized Daniel Defense Mk18 Upper Receiver Group which features the more subdued "Daniel Defense" logo.

** The low profile gas block is smaller than the Mk12 gas block. See pics for details This comes pinned or unpinned, in whichever fashion the factory is producing when you order. From time to time the factory sends with the Mk12 gas block. If you have a preference, let us know, but mostly, we get what we get.
*** Standard mil spec charging handle, which has been standard with DD Mk18's for years. Some versions have the newer Rip and Grip, which is an upgrade option at Charlie's.
Please feel free to ask questions before you buy.
All NFA laws apply. You need to make sure you can own it, in the configuration in which you attach to a lower receiver. This can be a pistol or a rifle, when assembled. If assembled as a rifle, it will be short barreled rifle, and subject to NFA laws. Owning the upper and a rifle lower could also be considered an NFA item. If you are uncertain if you can own this, check federal National Firearms Act, also with your state authorities.
Note: All ITAR regulations apply. Charlie's deals in the real McCoy. Your item most likely has parts that cannot be shipped outside of the USA, or owned in the USA by non-US Persons. You take accountability to safeguard parts and the entire upper, and get necessary approvals to transport outside of the USA.
