Daniel Defense DDM4 MK18 5.56 NATO AR Pistol with Law Tactical Folder & Geissele Trigger

The heart of this pistol is the 10.3-inch cold-hammer-forged, chrome-lined barrel with a 1:7 RH twist and a 1/2-28 threaded muzzle capped by the Daniel Defense Improved Flash Suppressor. This barrel profile is identical to the SOCOM-fielded MK18, delivering proven durability and consistent accuracy.
A Daniel Defense RIS II MK18 handguard (CAGE 3E2E2, NSN 1005-01-548-1385) provides 9.55 inches of rigid 6061-T6 aluminum rail space for lights, lasers, or grips while maintaining the pistol’s lightweight balance. The forged 7075-T6 receivers wear the company’s hard-coat black anodized finish for corrosion resistance.
The Law Tactical GEN3-M folder lets the brace assembly fold to the side, shortening the overall length for transport without affecting direct-impingement function when deployed. An SB Tactical SOB pistol brace offers adjustable length and solid cheek support.
A Geissele aftermarket trigger replaces the factory fire-control group, giving the shooter a clean, consistent pull that complements the pistol’s inherent accuracy. All components are factory-installed and properly timed for reliable operation.
