The Daniel Defense MK18 Pistol is a variation of the MK18 SBR, 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 railed forend Daniel Defense currently provides to USSOCOM and a 10.3” Cold Hammer Forged Barrel, the same length commonly used for CQB operations. The MK18 RISII features our patented 6-bolt Bolt-Up System and has been rigorously tested prior to fielding by USSOCOM. This pistol comes equipped with the SB Tactical SBA3 Pistol Stabilizing Brace with 5 positions of adjustability and integral, ambidextrous QD swivel attachment point. The new independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters and is engineered for suppressed fire, with anti-gas features that redirect gas flow upward and away from the face and operator.
