What if you took a look around and Geissele made a smaller brother to the M4 URGi, and what if it happened to be 10.3" and someone called it a Mk18 Mod X. We don't know either.
This model is the Geissele clone correct upper, in a shorter close-quarter battle rifle (CQB) configuration. Charlie's has worked closely with Geissele to bring you what you are looking for.
Your choice of the Surefire 4-prong flash hider, or other great Surefire, Colt, BE Meyers and KAC flash hilders.
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.
Note: This is 100% Geissele and Colt. Geissele has assembled the barrel and pinned a Geissele low profile gas block. 4-prong Surefire flash hiders have been timed and installed by Geissele. The 3-prong flash hiders have been installed and the barrel assembly and Geissele rail has been assembled by Potomac Armory for Charlie's to bring you the clone correct version of this URG.
Note: if you select WarComp, we time this as neutral (ports pointed up). If you want it timed to the starboard side, please make sure to put that in the comments. Both are correct. Our gunsmiths prefer ports timed up.
NFA warning: The Stripped URGI upper receiver group without the pinned flash hider 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. Please make sure you fully understand NFA and local laws.
ITAR warning: This item may only be purchased and shipped to US Persons within the USA. This is a military item, which is restricted from export without US Government permission.
