Daniel Defense MK12 SPR Features
From its origin with the U.S. Army Marksmanship Unit to its refinement by Daniel Defense, the MK12 was designed as a purpose-built AR-15 Precision rifle. The 18-inch MK12 profile barrel, made of proprietary stainless steel, is DLC finished for enhanced accuracy and barrel life. Cold hammer forging ensures perfect chamber-to-bore alignment for maximum consistency, and the rifle-length gas system paired with a Crane-spec MK12 gas block delivers smooth recoil and operational reliability.
The MK12 includes a free-floating DDM4 12.0 quad rail for optics and accessories, a Daniel Defense flash suppressor, and a BCMGUNFIGHTER charging handle for optimal manipulation under stress. Inside, the Geissele SSA 2-stage trigger provides a crisp break and smooth pull, raising the bar for AR-15 Caliber 5.56mm precision shooting. Daniel Defense’s soft-touch pistol grip and buttstock offer superior ergonomics, while the rail panels resist heat up to 300°F for hard use. Made in the USA, the MK12 combines elite features and unmatched build quality.
