Daniel Defense MK12 Semi-Automatic Centerfire Rifle

The MK12 rifle from Daniel Defense represents the evolution of the SPR (Special Purpose Rifle) concept, now brought home to Daniel Defense and made available to the public. This rifle has a rich heritage, being born out of necessity, refined through the Army’s Marksmanship Unit, and built to meet Daniel Defense’s stringent Mil-Spec+ standards.

At the heart of the MK12 is its 18-inch Stainless Steel barrel, crafted using the Cold Hammer Forging process. This method ensures exceptional alignment between the chamber and bore, resulting in unparalleled accuracy. Additionally, the barrel is finished with a DLC (Diamond-Like Carbon) coating, enhancing both durability and performance.

The MK12 barrel incorporates a rifle-length direct impingement gas system, utilizing the Crane Specifications for USSOCOM. To maintain precision and reliability, the rifle features the MK12 gas block, machined from 416 stainless steel and coated with Black Oxide.

The rifle’s internals includes an M16 profile bolt carrier group and a BCMGUNFIGHTER Charging Handle, providing smooth and efficient operation. The upper receiver is equipped with a free-floating DDM4 Rail 12.0 quad rail, allowing users to attach optics and accessories of their choice. The Daniel Defense Improved Flash Suppressor completes the upper receiver assembly.

Since the MK12 is designed as a precision rifle, it incorporates several refinements. One notable feature is the Geissele SSA 2-Stage Trigger, which offers a two-stage design to enhance the shooter’s ability to deliver precise and accurate fire on the target. The rifle is also outfitted with the comfortable and rugged Daniel Defense Buttstock and Pistol Grip.

Overall, the MK12 rifle represents a culmination of experience, expertise, and high-quality components. It embodies the precision and reliability required by marksmen seeking an exceptional rifle for a variety of applications.
