The US Army Special Operation Command is changing out the M4 upper receivers with this new improved model, which features the Geissele Mk16 DDC rail, and a Daniel Defense 14.5" Government profile mid-length barrel
This version is a stripped model, so it does not have a BCG or flash hider and charging handle.
Each URGI is fitted with the handguard Geissele designed specifically for USASOC, the MK 16 M-LOK™ Super Modular Rail handguard with a full-length Picatinny top rail and lotsa slots for other accessories. T-markings are engraved on the rail but not painted white to help keep the rifle unobtrusive.
