This is the brand new Upper Receiver Group-Improved, URG-I, from Geissele. This is a near clone upper of what the US Army Special Operations Command is issuing to their members. This upper group improves the overall capabilities of the M4 currently in service. When installed on a existing lower receiver this upper group essentially makes a whole different firearm.

The stripped upper includes a mil-spec M4 upper receiver, Geissele SMR MK16 M-LOK rail and a Daniel Defense 5.56mm government cut, cold hammer forged barrel with a mid length gas system.


***NFA DISCLAIMER/WARNING: The non-pinned and welded clone URGI upper receiver does not meet the 16″ minimum barrel length requirement, and requires registration and a tax stamp with the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) when assembled into a complete rifle.  Additional state and local restrictions may apply. It is the sole responsibility of the buyer to comply with any and all applicable laws.***

    Unfortunately no. These are a $900 rail and we had to discount it 30% just to move it at a loss :(
