Geissele URG-I MK16 14.5″ Complete Upper, 5.56 NATO

Description

The Geissele Automatics URG-I MK16 complete upper pairs a Geissele Super Modular Rail MK16 handguard with a chrome-lined, hammer-forged 14.5-inch barrel and a mid-length gas system to create a factory-configured upper for AR-15 platforms. Built as a near-clone of the USASOC URGI configuration, the assembly is designed to work with modern .223 Rem/5.56 NATO ammunition, including M855A1. The package uses a mil-spec M4 receiver profile and a DDC (Desert Dirt Color) M-LOK handguard for a durable, configurable interface. This URG-I upper is intended for shooters who want a ready-to-fit complete upper that emphasizes serviceability and system compatibility.
