The MK18 AR15-style Pistol is inspired by the original MK18, which has been extremely popular with Law Enforcement and Special Operations communities. The MK18 Pistol features the Picatinny quad rail that 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 our patented 6-bolt Bolt-Up System and has undergone rigorous testing before fielding by USSOCOM. This pistol comes equipped with the SB Tactical SBA3 Pistol Stabilizing Brace, which offers 5 adjustable positions and an integral, ambidextrous QD swivel attachment point.
