The MK18 AR15 style Pistol, equipped with the SB Tactical SOB Pistol Stabilizing Brace and LAW Tactical GEN3M folding stock adapter, is inspired by the original MK18, which has been extremely popular within the Law Enforcement and Special Operations communities. This firearm is classified as a Pistol and not a Short Barreled Rifle (NFA regulated items require ATF approval and a tax stamp). The Daniel Defense MK18 Pistol features the picatinny quad rail Daniel Defense currently provides to USSOCOM and a 10.3 inch Cold Hammer Forged Barrel, the same length commonly used for CQB operations. The MK18 RISII features the Bolt-Up System and has been rigorously tested prior to fielding by USSOCOM. The independently ambidextrous GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters. This pistol comes equipped with the ergonomic Daniel Defense Pistol Grip with an integral trigger guard and soft touch overmolding.
