Geissele URG-I Near Clone 5.56 NATO 11.5" 1:7" Gov Bbl DDC Complete Upper Receiver Group w/10.5" M-LOK MK16 SMR 08-315

The Geissele URG-I 11.5 upper is as close as civilian buyers can get to the actual upper receiver group currently fielded by the U.S. Army Special Operations Command. The URG-I 11.5 Near Clone replicates the USASOC configuration with the same components, the same specifications, and the same manufacturing standards that Geissele supplies to the military — in Desert Dirt Color for the shooters who want the authentic look alongside the authentic performance.

The Geissele 11.5 barrel is cold hammer forged with a 1:7-inch twist rate, chrome-lined, and manganese phosphate-coated for outstanding durability and wear resistance. The carbine-length gas system pairs with a Super Compact Gas Block and .067-inch gas port size specifically optimized for reliable cycling with M855A1 AB57 ammunition — the same ammunition configuration that drove the USASOC upper receiver group specification in the first place.

The Geissele URG-I Reliability Enhanced Bolt Carrier Group features Nanoweapon coating, a properly staked and chrome-lined gas key, and a Stressproof Bolt machined from Carpenter 158+ bar stock for greater strength and fatigue resistance than standard bolt materials. The 11.5" upper receiver is paired with a Geissele 10.5-inch SMR MK16 handguard in DDC — a lightweight, modular rail platform that provides full-length accessory mounting without the weight penalty of longer handguard systems. The Geissele Airborne Charging Handle in DDC and SureFire SF4P 4-prong flash hider complete the external components.

The Upper Receiver Group includes a Super 42 Braided Wire Buffer Spring and H3 Buffer Combo for optimal recoil management — the same buffer system Geissele specifies across their complete rifle builds for reliable cycling and felt recoil reduction.

At 3 pounds 8 ounces and 21.25 inches overall, the URG-I 11.5 upper delivers USASOC-spec performance in a compact, capable package. Find the Geissele URG-I Near Clone 11.5" DDC Complete Upper Receiver right here at EuroOptic.
