Daniel Defense MK18 SBR 5.56mm NATO 10.3″ Threaded Barrel Black – NFA Item

The Daniel Defense MK18 SBR is the gold standard in short-barreled rifles, purpose-built to mirror the exact configuration issued to U.S. Special Operations Command (USSOCOM). Chambered in 5.56mm NATO and equipped with a 10.3-inch Cold Hammer Forged barrel, this NFA-regulated firearm delivers exceptional accuracy, durability, and compactness purpose-built for close-quarters battle (CQB) operations.

At the heart of the MK18 is the iconic RIS II Picatinny quad rail, featuring Daniel Defense’s proprietary Bolt-Up System — rigorously field-tested and approved by USSOCOM. The 1/2×28 threaded muzzle allows for suppressor or muzzle device attachment, while the ambidextrous GRIP-N-RIP Charging Handle ensures smooth, reliable manipulation for both left- and right-handed shooters. The package is completed by Daniel Defense’s ergonomic buttstock and pistol grip, providing a consistent, comfortable cheekweld and firing platform in any condition.

Includes one 32-round magazine. Finished in a durable matte black, this SBR is as mission-ready as it is refined.
