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, use a black nitride 4140 tunable steel gas block and a stainless steel gas tube.
