The Geissele USASOC 14.5" Improved Complete Upper receiver lets shooters put a custom take on the Upper Receiver Group Improved (URGI) being adopted by the United States Army Special Operations Command (USASOC) forces. The complete Upper Receiver Group Improved upper is built around a proven 14.5" cold hammer forged government contour barrel, topped with a SureFire 4-prong flash hider. The Geissele Airborne charging handle has been selected for ambidextrous charging with minimal snagging.

The Geissele URG-I Upper 14.5-inch configuration is a near-clone of the USMC's URG-I upper receiver group — built to the same specifications and assembled with the same Geissele-quality components that make the military version the standard for serious operational use. For shooters who want a complete URG-I 14.5 upper that replicates the current USMC configuration in Desert Dirt Color, this is the most authentic civilian-available version of that setup.
