Geissele USASOC AR15/M4/M16 Upper Receiver Complete Group 08-159 Caliber: 5.56x45mm NATO, Barrel Length: 14.5 in, Includes Blazin' Deal w/ Free S&H
The muzzle device is pinned and welded, so you would have to take the barrel to a machine shop or qualified gunsmith to permanently remove the flash hider.
I purchased the Geissele URGI for my next build and the transaction could not have been simpler. Although "Availability" indicated approximately 13-24 days to ship, it actually shipped within a couple of days and I received the entire order within 8 ...

Geissele took the upper in under warranty and re-barreled it, had it back in about a month. 450 rounds in and no issues, all types of ammo. Getting sub moa at a hundred yards suppressed with AAC 5.56 55g. Gla...

Geissele is making some of the best products. This is no different. I love this upper along with the super duty upper as well. This one is a tad bit lighter due to the rail system. But it shoots very well and doesn’t wear out fast. The added super 4...

Extremely durable duty grade upper. I would trust my life to the ability of this upper to perform in any condition or environment. Keep in mind that this is not a true clone and does not have the DD barrel but instead an Geissele in house CHF barrel.
Honestly haven’t shot this particular upper,however, this is not my first URG-I. Previous URG-I had Daniel defense barrel and a generic mil spec bcg.
Upon first inspection fit and finish seems fine. Bcg shows some tooling marks but the actual bearin...

Product Info for Geissele USASOC AR15/M4/M16 Upper Receiver Complete Group
For more than 50 years, the famed silhouette of the M16/M4 has only had one major and several minor changes. Barrel lengths and buttstocks have changed, but more or less the evolution of America's right arm has proceeded apace with each generation of warrior making her their own. In that time, the sight of the M16/M4 in the competent grasp of young Americans has meant hope to countless millions of people around the globe.
With the advent of the Geissele USASOC AR15/M4/M16 Upper Receiver Complete Group, that quintessentially American silhouette has changed forever. The Geissele USASOC AR15/M4/M16 Upper Receiver Complete Group combines the handguard, hammer forged barrel, and mid-length gas system to work in concert for a package that delivers measurable increases in hit probability. Designed to take the full rigors of the new M855A1 (AB57) ammunition, these AR15 Upper Receivers also take full advantage of its capabilities. Once the Geissele USASOC AR15/M4/M16 Upper Receiver Complete Group is installed on an existing system, it essentially makes for a brand new weapon. It is a near-clone upper receiver group currently going into service with USASOC.
NFA DISCLAIMER/WARNING: This item contains a permanently pinned and welded muzzle device. This makes the muzzle device an integral part of the barrel to make the barrel meet the 16" minimum length requirement, and requires no registration or tax stamp from the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE). Removal or modification to the muzzle device, will result in converting this item to a regulated item by the National Firearms Act (NFA). Additional state and local restrictions may apply.
