The Geissele Automatics Super Duty Assembled Upper arrives with dust cover and forward assist installed, precision machined to mil-spec from 7075-T6 aluminum forging, ready to accept a barrel, handguard, BCG, and charging handle of your choice. This unit is finished in Luna Black at a blem price; function is unaffected.

The Super Duty Assembled Upper Receiver is a mil-spec AR-15 assembled upper machined from 7075-T6 aluminum forging at the Geissele facility, designed as the structural foundation for a custom AR-15 upper receiver group build.

Coming pre-assembled with a dust cover and forward assist, the Super Duty upper saves builders the assembly steps often skipped or done incorrectly on stripped uppers. M4 feedramps are machined in, supporting reliable feeding across a wide range of BCG and barrel combinations. Milled T-Marks provide a positive reference for handguard installation. The receiver accepts all mil-spec barrels, handguards, BCGs, and charging handles, giving builders full flexibility to configure their upper to their application. Finished in Luna Black Type 3 Hardcoat anodize. Note: shade variance between this and other Luna Black components is expected and normal.

Compatible with all mil-spec AR-15 barrels, handguards, BCGs, and charging handles. Required to complete: barrel, muzzle device, handguard, BCG, and charging handle (not included). Review Geissele's Anodize Shade Variations and Finish Methods notice before purchase.

Machined from 7075-T6 aluminum forging with Type 3 Hardcoat anodize in Luna Black, providing the corrosion resistance and surface hardness expected of a mil-spec upper receiver built for sustained use.

An ideal starting point for a custom mil-spec upper build, a replacement upper for an existing lower, or a direct-fit companion to Geissele Super Duty handguards and barrels in Luna Black.

Geissele Automatics manufactures all components at their North Wales, Pennsylvania facility with quality assurance processes aligned to direct U.S. military procurement standards.
