Details
NOTE: This upper assembly has a barrel less than 16” in length. These uppers are intended for use in AR-15 pistols or legal short-barreled rifles. Other configurations may violate Federal law.
With the Geissele Automatics USASOC Improved Complete Upper Receiver, you can build a near-clone of the URGI 5.56 carbine. This Geissele AR-15 complete upper receiver features the 10.3” cold hammer forged barrel with a carbine length gas system and tuned to take full advantage of the M855A1 ammunition. The Geissele Super Gas Block features a low-profile design and is pinned to the barrel for a bombproof installation. The barrel is threaded 1/2x28 and features the Surefire SF4P 4 prong flash hider. This version uses the 9.3” MK16 free floated M-LOK handguard that protects the gas block while leaving enough room for a suppressor to be attached. One of the toughest handguards on the market, the MK16 offers plenty of options for setting up your AR however you see fit and features a desert dirt anodized finish.

The M4 flat top upper receiver is built to Mil-Spec dimensions out of 7075-T6 aluminum with a type III hardcoat anodized finish. This complete upper receiver group comes with a Geissele enhanced bolt carrier group and the Geissele Airborne ambidextrous charging handle as well as the Super 42 braided wire buffer spring. It attaches to any Mil-Spec lower receiver group with pistol buffer tube or legally registered SBR lower, so you can have a completely new weapon system. This complete upper group features many of the parts used on the USASOC URG-I weapon system but is designed for civilian semi-automatic AR-15 lower receivers.
Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.

Giessele 10.3 U.R.G.I
by Josh
One of the best uppers on the market! I have very little gripes with this upper. One gripe is that it’s pretty expensive. In the long run I think it’s worth it; but it’s definitely expensive. Other than that this upper is a fantastic! Super solid build and made for hard use. I have put around 600-800 rounds through it with no problems. The Daniel Defense 10.3 barrel is really accurate for being as short as it is. My best groups sizes were
1 1/8 to 1 1/4 inches at 100 yards. The 4 prong Surefire flash hider works great and definitely will catch the eye of those cloners at the range. The charging handle is great and I won’t be switching it out, but I still prefer the Radian Raptor by the slightest margin. The braided buffer spring pared with the H3 buffer worked great and is nicely included. The rail is my favorite M-LOK rail on the market! Super strong and tough yet lightweight. Overall a fantastic upper! Highly recommended
Top quality upper!

I’ve had this upper for almost a year now. It’s a true blast to shoot. If you want a quality bomb proof upper, don’t sacrifice as the Geissele USASOC is the way to go.
Not what I expected.

One year review for Giessele 556 10.3 near clone. Purchased 4/19 on sale direct from PA. As usual, no issues with PA AT ALL.
However, this particular upper is a disappointment. Have to admit, no mechanical/ cycling issues but accuracy is just not there, at the very best you are going to hit 10" gong at 100 yards if you are lucky, heavier ammo actually performs worse in this upper. I have sent it back to Gisele to be checked and, of course, no issues was found all "within" specs. My home made builds with comparable length BA barrels do a LOT better than this thing. Suppressor adapter as sexy as it looks constantly sticks to my Surefire suppressor after short periods of use making it difficult to remove, again no issues with the regular commercial Surefire muzzle devices. Bottom line unless you really want a "near clone" your money is best spent on something else.
