Geissele URG-I Near Clone Complete Upper 14.5"

The Geissele URG-I Near Clone is the closest commercial near-clone of the USASOC Upper Receiver Group - Improved (URG-I), the 14.5" upper that replaced the SOPMOD Block II carbines across U.S. Army special operations. Geissele built the original government program and sells the commercial Near Clone with the current commercial near-clone configuration: a 14.5" cold hammer forged government-profile barrel, a mid-length gas system, the MK16 M-LOK rail in Desert Dirt Color, and a Reliability Enhanced Bolt Carrier Group. This is not a Super Duty variant; it is the dedicated URG-I product line and the reference upper for anyone assembling a URG-I, Block II, or SOCOM-pattern clone.

The 14.5" barrel is cold hammer forged from 41V50 chrome-moly-vanadium steel with a government profile, 1:7 twist, and chrome lining for service-rifle durability. The mid-length gas system runs off a pinned Geissele low-profile Super Gas Block, the same softer-shooting, more reliable gas dwell that defined the URG-I over the shorter carbine-gas Block II uppers. A SureFire SF4P four-prong flash hider sits at the muzzle, permanently pinned and welded. That pin and weld takes the 14.5" barrel past 16" of permanent length, so the assembled upper is rifle-legal on a standard lower with no SBR paperwork and no NFA registration.

Geissele includes the parts that make the URG-I run: the Reliability Enhanced BCG (REBCG) with the Geissele bolt and coating, the Airborne Charging Handle in DDC, and a Super 42 braided wire buffer spring paired with an H1 heavy buffer. Drop it on any mil-spec lower and the package is complete from the charging handle back to the buffer system. The 13.5" MK16 rail gives near-full-length sight radius and accessory real estate over the mid-length gas block while keeping the slim, light profile the URG-I is known for.
