Geissele Automatics URG-I Near Clone Complete AR-15 Upper Receiver - 5.56 - 11.5" - FDE

The Geissele Automatics URG-I Near Clone Complete AR-15 Upper Receiver in DDC replicates the Upper Receiver Group Improved fielded by USASOC, pairing a 11.5" cold hammer forged barrel with the Geissele MK16 handguard built to that program's specification.

Features:

• 11.5" cold hammer forged 41V50 chrome moly vanadium barrel, government profile, chrome lined, 1:7 twist
• Carbine-length gas system with pinned Geissele Super Gas Block
• SureFire SF4P 4-prong flash hider, compatible with SureFire SOCOM-series suppressors
• 10.5" Geissele MK16 free-float M-LOK handguard, DDC finish
• Geissele Airborne charging handle, DDC finish
• Geissele Reliability Enhanced bolt carrier group
• Integral QD sling swivel sockets
• Super 42 braided wire buffer spring

USASOC specified a government-profile barrel and carbine-length gas system for this platform after extensive testing, balancing weight against stability and reducing felt recoil and wear compared to a carbine-length system. The MK16 handguard's M-LOK slots run across multiple surfaces so lights, lasers, and grips can be mounted exactly where needed without offset mounts, and the integrated QD sling sockets skip the added weight of separate hardware.

Because this 11.5" barrel measures under 16", this complete upper is intended only for an AR pistol or a legally registered short-barreled rifle — attaching it to a standard rifle lower without the correct configuration violates federal law.

Geissele Automatics built its reputation on the Hi-Speed National Match trigger, later adopted by U.S. Special Operations for a select-fire variant, and now applies that same quality control to complete upper receivers for warfighters, competitors, and civilian shooters alike.
