Daniel Defense DDM4 MK12 5.56 NATO Rifle

The Daniel Defense DDM4 MK12 is a semi-automatic rifle built around an 18-inch cold hammer forged stainless steel barrel treated with a durable salt bath nitride finish. Its rifle-length gas system and MK12 low-profile gas block follow United States Special Operations Command specifications, while the Geissele SSA two-stage trigger supports a controlled and consistent trigger press. The DDM4 12-inch rail provides a continuous upper rail for mounting an optic and offers an extended sight radius for compatible backup sights. A Daniel Defense Improved Flash Suppressor completes the muzzle configuration.
