Geissele Upper Receiver Group, USASOC URG-I
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.
This is a brand new Geissele stripped URG, open box (or no box). Some handling marks and missing instructions and promotional stickers. Only the URG is inlcuded. -- only a few, and we need to clear-out
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.
Core receiver with forward assist, shell deflector & ejection port cover

Daniel Defense 14.5" CHF barrel with 1-7" rifling & 1/2"-28 tpi muzzle threads and mid-length gas system

Please make sure you fully understand NFA and local laws.
I’m a clone nerd, this upper is amazing, I chose the stripped version mainly because I run it on an sbr lower so didn’t want the pinned hider. I know that meant no 4 prong for detail, I have the surefire 3 prong on almost all my setups, the only thing I’ve heard is that the 3 prong has stronger prongs and provides pretty awesome flash reduction during the day you don’t see a flash at night a small flash nothing like a standard a2 hider would do. The rail was made to with stand the rigors of what a socom operator may incounter. So the rail is a bit heavier than say a bcm mcmr mlok rail. Yes the bcm is lighter but socom wanted something that could be abused to hell and back!! The upper reciver I believe is produced by aero on this version unlike the colt upper on the clone version. It pre forms great, I installed a colt bolt and Bcg, let’s not forget the airborne charging handle. It has an amazing feel to it, I know a lot of guys love the standard geiselle charging handle. This one has shorter arms so it has less of a chance of snagging on your gear, and as the name states “airborne”, this was from what I’ve read meant for the bad ass dudes that do airborne jumps into enemy territory, they were having issues with the longer arms snagging there fear making it a pain to get the rifle up and there shouts backed. Now there’s less of an issue of that now for us civilians it just looks good feels good and is very smooth when charging the firearm. There’s nothing wrong with the stripped version, that’s if you have an sbr lower already or you just want to choose your own flash hider and have a local gunsmith pin it on for you. The max I’ve got to fire at is 30 yards lol. Haven’t made it to the outdoor range yet. Here’s something a lot do not know about this upper is it’s slightly over gassed, but for a reason mainly so the gun can operate in dirty conditions more reliably. Do you get gas to the face? Not that I have noticed the charging handle was designed to in the rear by were you’d grab it, has a gas buster type deal going on. I haven’t shot it suppressed so I’m sure you may get some watery eyes rapid firing with a suppressor. Finally your thinking damn it’s over gassed more recoil omg oh nooooo, well actually it’s quite tame, specially after I threw the geiselle super 42 buffer spring and buffer that made a huge difference. I ordered the tungsten inserts for the buffer to make it an h2 or h3, the spring it self is 15% stronger than a standard buffer spring, I also run a mk18 on this lower I noticed a great difference in recoil on the mk18 with the super 42 spring. Lastly you can’t go wrong with this upper specially if your a cloner and want something that’s not even issued to our troops yet you’ll be ahead of the game lol. Thou the usgi version uses a different bolt and buffer look up the AROC rifle project for details. I’m really looking forward to the mk18 version of this upper. I’ve seen some photos and wow it looks good. I don’t want to mention again don’t think this is a light weight 3 gun upper, why because it’s not meant for 3 gun it’s meant to withstand the rigors of combat and abuse the thicker diameter makes this thing bomb proof and yes it is lighter than the Blockii dd upper in 14.5. Yes I own both lol. — Steve “lurkface” Mellion
