Product Description

What's in the Box

  • Daniel Defense MK12 5.56 NATO AR15 Rifle
  • (1) 32-Round DD Magazine
  • Cable Lock
  • Owner's Manual

The evolution of the SPR comes home to Daniel Defense in the MK12. This firearm 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 DLC 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 new independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters and is engineered for suppressed fire, with anti-gas features that redirect gas flow upward and away from the face and operator. 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.
