Geissele URGI CHF Barrel 5.56 Complete Upper Assembly Black/DDC Anodized-MK16 HG - 11.5

Geissele URGI CHF Barrel 5.56 Complete Upper Assembly Black/DDC Anodized-MK16 HGFor 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 own. In that time, the sight of the M16/M4 in the competent hands of young Americans has meant hope to countless millions around the globe.With the advent of the USASOC URGI, that quintessentially American silhouette has changed forever. The Geissele Super Modular Rail MK16 handguard, hammer-forged barrel, and mid-length gas system work in concert to deliver measurable increases in hit probability. Designed to take the full rigors of the new M855A1 (AB57) ammunition, the USASOC URGI also takes full advantage of its capabilities. Once the USASOC URGI is installed on an existing system, it effectively becomes a brand-new weapon. The USASOC URGI is a near-clone of the upper receiver group currently in service with USASOC.Specifications Mil-Spec M4 Upper Receiver Assembly Geissele Reliability Enhanced Bolt Carrier Group Geissele Airborne Charging Handle, DDC SureFire SF4P 4 Prong Flash Hider, Pinned & Welded Super 42 Braided Wire Buffer Spring and H1 Buffer Combo Included14.5" Upper Geissele SMR MK16, DDC, 13.5" Geissele 5.56MM 14.5" GOV profile, CHF, Chrome Lined, Mid-Length Gas, Mag Phos, ChromolyV, 1/7 Twist, Barrel Geissele Super Gas Block .750 Low-Profile Gas Block, Pinned (Bombproof Installation) Gas Port Size: .076"11.5" Upper Geissele SMR MK16, DDC, 10.5" Geissele 5.56MM 11.5" GOV profile, CHF, Chrome Lined, Carbine Gas, Mag Phos, ChromolyV, 1:7 Twist, Barrel Geissele Super Gas Block 0.067 Low-Profile Gas Block, Pinned (Bombproof Installation) Gas Port Size: .067"*Due to varying contract specifications, some variation may occur.
