AR 15 Upper Receiver Assembly – Overview
The iconic M16/M4 silhouette has seen only one significant and few minor alterations. Although AR 15 Upper Receiver Assembly barrel lengths and buttstocks have altered, the evolution of America’s right arm has continued apace, with each generation of warriors making her their own. Also, the sight of the M16/M4 in the capable hands of young Americans at the time meant hope to untold millions of people all over the world.
In addition, with the introduction of the USASOC URGI, the iconic American shape was forever altered. The Geissele Super Modular Rail MK 16 handguard, hammer forged barrel, and mid-length gas system all work together to produce quantifiable gains in hit probability. The USASOC URGI is designed to withstand the full rigors of the new M855A1 (AB57) ammo while also taking full advantage of its capabilities. When the USASOC URGI is placed on an existing system, it effectively creates a new weapon. Also, the USASOC URGI is a near-clone upper receiver group that is currently in service with the USASOC.
Furthermore, this item has a permanently pinned and welded muzzle device, which is a violation of the NFA.

The National Firearms Act (NFA) will apply its regulations to this item if the muzzle device is removed or otherwise altered. There may be further local and state restrictions. Equally important, the customer is solely responsible for adhering to any and all laws applicable.
