in Case Daniel Defense MK12 AR-15 chambered in 5.56mm. The MK12 is
constructed around an 18-inch Stainless Steel barrel with a chamber
created during the Cold Hammer Forging process, which ensures the most
precise alignment of the chamber to the bore possible. This, along with
being salt bath nitride finished, equates to unprecedented accuracy and
durability. The MK12 barrel is engineered with a rifle-length direct
impingement gas system and utilizes the MK12 gas block, which is built
to Crane Specifications for USSOCOM. The MK12 gas block is precision CNC
machined from 416 stainless steel and Black Oxide Coated. The rifle is
fed with a M16 profile bolt carrier group and uses a Vltor Mod 4
charging handle for ease of operation. The upper receiver is equipped
with a free floating DDM4 Rail 12.0™ quad rail for allowing your choice
of optics and accessories and is finished off with a Daniel Defense
Improved Flash Suppressor.
The MK12 was designed from the ground up to be a precision rifle, therefore it required certain refinements. We equipped it with the Geissele SSA® 2-Stage Trigger to give the marksman an advantage delivering precise fire to the target. We also furnished the MK12 with the newly designed, rugged and comfortable Daniel Defense Buttstock and Pistol grip.
