Daniel Defense DDM4 MK18 5.56 Pistol 10.3" SBA3 Brace 32rd

The Daniel Defense DDM4 MK18 delivers proven close-quarters performance in a compact pistol configuration. This 5.56 NATO platform combines military-proven reliability with civilian accessibility through its SB Tactical SBA3 stabilizing brace.

What Makes This Different

Built on the legendary MK18 platform used by special operations forces worldwide, this pistol features Daniel Defense's proprietary DDM4 rail system and cold hammer-forged barrel. The 10.3-inch barrel length optimizes ballistics for 5.56 NATO while maintaining maneuverability in confined spaces. Unlike standard carbine-length systems, the MK18's shorter profile reduces overall length by 5.5 inches without sacrificing terminal performance at typical engagement distances.

Key Features

• Cold hammer-forged 10.3" barrel with 1:7 twist rate for optimal bullet stabilization
• DDM4 free-floating handguard with continuous Picatinny top rail and M-LOK attachment points
• SB Tactical SBA3 adjustable stabilizing brace with five-position length adjustment
• Ambidextrous safety selector and magazine release for enhanced shooter versatility
• Black hardcoat anodized aluminum receivers with Type III finish for corrosion resistance
• Includes 32-round Magpul PMAG and overmolded pistol grip
• Threaded 1/2x28 muzzle with A2 flash hider for suppressor compatibility

The MK18's gas system timing ensures reliable cycling with both standard and subsonic ammunition loads. The platform functions effectively in temperatures from -40°F to 140°F and maintains accuracy standards of 2 MOA or better with quality ammunition. Law enforcement agencies report consistent performance through 10,000+ round service cycles with minimal maintenance requirements.
