The MR762A1 uses a proprietary HK short-stroke gas piston in place of the direct-gas-impingement system found on lesser AR15-style rifles that propels exhaust gas into the upper receiver to operate the action. In the “closed” HK piston system, exhaust gasses never enter the receiver, which means the HK runs cooler, cleaner and more reliably. And when adverse conditions, like dust, sand and mud are introduced, the advantage of the HK system becomes even more drastic. That is why so many of the world’s elite military and law enforcement customers have absolute trust in their HKs. The MR762A1 has a cold hammer forged barrel made from the highest quality cannon-grade steel, producing a barrel that ensures superior accuracy, even after firing thousands of rounds. And while the material and cold hammer forging process themselves greatly enhance durability, HK’s processes include many additional steps not taken by other manufacturers to produce superior accuracy and service life, ensuring performance well beyond “mil-spec.”

The DD5 V4 chambered in 7.62x51mm NATO / 308 WIN provides users of the Daniel Defense semi-automatic platform even greater long-range precision shooting capability. The highly popular 6.5 Creedmoor takes advantage of superior ballistic coefficients to offer both flatter trajectories and reduced wind drift at levels normally reserved for much heavier recoiling long action calibers. These gains in ballistic efficiency help the modern shooter stretch the effective range out to 1000 meters or more. This highly accurate and durable rifle includes an adjustable gas block that allows for a consistent feel whether shooting suppressed or unsuppressed. The perfected bolt carrier group reduces overall recoil impulse and is easy to maintain and operate in all conditions.
