The Daniel Defense MK18 Pistol 5.56 NATO with the SBA3 brace (brand part no. 02-088-01202) is inspired by the original MK18 configuration popular with law enforcement and special operations units. Daniel Defense builds it around a 10.3-inch cold hammer forged barrel and the RIS II MK18 Picatinny quad rail it supplies to USSOCOM. It ships with a Daniel Defense 32-round magazine, and the SB Tactical SBA3 Pistol Stabilizing Brace has five positions of adjustment. The GRIP-N-RIP charging handle works from either side for left- and right-handed shooters.
