Description
The Daniel Defense DD4 SPRIII is a semi-automatic AR-15 rifle chambered in 5.56x45mm NATO, designed as a successor to the Mk12 Special Purpose Rifle for precision shooting applications. It is finished in black anodized aluminum and ships without iron sights, making it suited to optics-equipped setups.
The rifle weighs 8.6 pounds and measures 34.75 inches overall with an 18-inch threaded barrel. Its 32-round capacity, ambidextrous lower controls, and optics-ready configuration complete the core specifications. The barrel is available in a threaded configuration with a flash suppressor included.
The package includes a hard impact plastic case with a full-latch closure. The rifle is built on the AR-15 platform, so it accepts compatible AR-15 accessories and magazines.
