The Daniel Defense MK18 RIII in Flat Dark Earth handguard and black receivers delivers the iconic MK18 configuration trusted by elite units worldwide, now enhanced with the lightweight, M-LOK-equipped RIS III rail system. Retaining the exact 10.3" Cold Hammer Forged, chrome-lined government-profile barrel that made the MK18 the gold standard for CQB, this factory SBR pairs SOCOM-proven free-float performance with modern versatility: uninterrupted 1913 top rail, seven M-LOK surfaces, and dual integral QD sling points. The two-tone FDE rail on black anodized receivers gives it an aggressive, purpose-built look that stands out on the range or in the stack. Every critical component is pure Daniel Defense quality: fully Mil-Spec 7075-T6 receivers with flared magwell, independently ambidextrous GRIP-N-RIP charging handle, H-buffer-tuned carbine gas system, properly staked chrome-lined M16 BCG, and Daniel's legendary ergonomic furniture. At only 5.73 lbs and collapsing to 26.75", it remains one of the fastest-handling, most reliable 5.56mm SBRs on the market while delivering rifle-grade accuracy and terminal effect.
