Forged Upper Receiver, 5th Gen

NOTICE: This batch of uppers has cosmetic issues with the dry film lube application that’s not up to our typical high standards, though still fully functional. Because of this, we are discounting these accordingly. 

Our latest forged upper receivers are manufactured to military contract specifications with machined M4 feed ramps. Available stripped or assembled with the forward assist and port door installed. We intentionally omit the traditional “T” markings on top of the Picatinny rail, so they better match unmarked handguard assemblies and likewise prevent mismatched engraving styles. Our deep laser engraved logo on top of the rail marks these as an Umbrella Corporation product. As with all our parts, they carry an unconditional guarantee against material defects and manufacturing failure. Barrel assembly should be performed by a qualified Armorer: Mil-Spec AeroShell 33MS/64 barrel nut grease included.
