Daniel Defense Mk18 SBR-Milspec

Use what the professionals use. The Daniel Defense MK18 is engineered to the same demanding standards as the rifles supplied to USSOCOM, making it one of the most trusted and battle‑proven short‑barreled rifles available today. Built for reliability in the harshest environments, the MK18 features the iconic railed forend used in military applications worldwide and a 10.3″ Cold Hammer Forged barrel designed for exceptional durability, longevity, and consistent performance. The Flat Dark Earth MK18 rail system incorporates the Daniel Defense Bolt‑Up System, a platform that has undergone extensive USSOCOM testing with more than 15,000 units successfully fielded in real‑world operations.

This 10.3″ barrel configuration is the same standard length found on MK18 upper receivers commonly chosen for CQB and confined‑space missions. Its compact size, smooth handling, and dependable performance make the MK18 Factory SBR an outstanding option for shooters who need a rifle that is quick, accurate, and responsive in critical situations. Despite its small footprint, it delivers exceptional control and reliability, making it one of the top choices for tactical users, professionals, and dedicated enthusiasts alike. The rifle also includes Daniel Defense’s redesigned Buttstock and Pistol Grip. Both are built with rugged materials and soft‑touch overmolding, offering exceptional comfort, secure grip, and user‑friendly ergonomics.
