Forged Upper Receiver

Description

Our latest forged upper receivers are manufactured to military contract specification with machined M4 feedramps. This stripped version ships without the forward assist or port door allowing the individual builder to use parts of their choosing. We intentionally leave off the traditional “T” markings on top of the Picatinny rail so they better match unmarked handguard assemblies (KAC, Vltor, etc.) and likewise prevent mismatched engraving styles. Our precision machined logo on top of the rail marks these as an Umbrella Corporation product. This generation includes an anti-rotation pin hole to accommodate handguards that support this feature. As with all of our parts, they carry an unconditional guarantee against material defect and manufacturing failure. Barrel assembly should be performed by a qualified Armorer: Mil-Spec AeroShell 33MS barrel nut grease is included.
