Daniel Defense AR-platform rifles have become synonymous with accuracy, so it’s no surprise that the manufacturer has produced its own accuracy-based precision rifle in the MK12. Designed for marksman and for military use, the MK12 features an 18” cold-hammer-forged barrel with MK12 contouring and 1:7” twist rate, which means it can handle the heavier loads. The rifle, chambered in 5.56 mm NATO, also features a DD4M quad-rail, a Daniel-Defense-designed flash suppressor, and special overmolded stock, also developed by Daniel Defense. Learn more in this “Rifleman Review” segment from a recent episode of American Rifleman TV.
