This Dirty Bird Industries Complete Upper features a Black Nitride 16" Sub-MOA Government Profile barrel chambered in 5.56 with a 1:7 twist. Built on a top-tier t-marked Forged Upper Receiver and finished with Dirty Bird's 15" SMRS M-LOK Handguard available in several color options. No corners are cut when manufacturing these complete uppers. All barrels are dimpled and cold blued, use a black nitride 4140 steel gas block and a stainless steel gas tube.
