Mk18 Mod 1 CQBR "near clone" URGi upper receiver group with DD Mk18 straight rail

The Mk18 Mod 1 is the short-barreled workhorse of Naval Special Warfare and Tier 1 units across the US military — and this CQBR near-clone URGi captures the current-issue configuration with the correct Daniel Defense Mk18 straight rail. Built around a 10.3" Colt-profile barrel in 5.56 NATO, carbine-length gas system, low-profile pinned gas block, and a mil-spec M4 flat-top upper with M4 feed ramps, this upper is ready to drop onto any mil-spec lower or NFA/Form 1 SBR project.

The DD Mk18 RIS II-style straight rail is the key detail on the Mod 1 — 9.5" top rail length, QD sling sockets, mil-standard cross-section, and the unmistakable FDE finish option (also available in black) that matches the current NSW TDP. Headspaced, test-fired, and assembled to URGi spec using genuine mil-spec and DD components. Not a "looks like" copy — a genuine near-clone built to the same standard the end users run downrange. Order yours today and bring home the upper that runs on Tier 1 rifles worldwide.
