Daniel Defense MK18 Upper

The MK18 upper receiver group with black RIS II Picatinny quad rail; 10.3” cold hammer-forged barrel; M4 feed ramps; DD flash suppressor; DD M4A1 RIS II MK18 handguard; DD rail panels; ambidextrous GRIP-N-RIP charging handle; and M16 profile bolt carrier group (BCG).

When it comes to size, weight and performance, the DD MK18 upper has very few rivals.

Featured on it is the railed forend Daniel Defense currently provides to USSOCOM, and the MK18 Rail Interface System (RIS II) features the Bolt-Up System that has been rigorously tested prior to fielding by USSOCOM. The cold hammer-forged barrel comes with a 10.3-inch Government profile, and is the same length most commonly used for CQB operations.

More features of the Mark 18 upper include an M16 profile, Mil-Spec MP-tested, chrome-lined BCG with a properly staked gas key; heat resistant (to 300O F) DD rail panels made from Santoprene; a DD flash suppressor made of 17-4 PH stainless steel and salt bath nitride-finished for enhanced wear and corrosion resistance; and a RIS II MK18 handguard Type III hard coat anodized for durability.

On this Daniel Defense DD MK18 upper is the new, independently ambidextrous GRIP-N-RIP charging handle that accommodates left- and right-handed shooters; this charging handle is engineered for suppressed fire, and boasts anti-gas features that redirect gas flow upward and away from the operator’s face.

CNC-machined of 7075-T6 aluminum, this Mil-Spec MK18 upper for sale at Mister Guns wears a Type III hard coat anodized finish just like the handguard, and is rounded out by indexing marks and M4 feed ramps that provide a lower, wider, and smoother entry for any round of ammo.
