The Geissele Super Duty Assembled Upper in DDC gives builders the same precision mil-spec upper receiver used across the Super Duty rifle line — complete with dust cover and forward assist pre-installed, M4 feedramps cut, and milled T-marks — ready to configure with a barrel, handguard, and BCG in Geissele's Desert Defense Color finish.

The Geissele Super Duty Assembled Upper Receiver is a complete AR-15 upper built to mil-spec standards, machined from 7075-T6 aluminum and finished in Type-3 hardcoat anodize in DDC. It ships fully assembled with dust cover and forward assist installed, M4 feedramps machined, and T-marks milled directly into the finish — ready to accept a charging handle, BCG, barrel, and handguard combination of the builder's choice.

Geissele's Super Duty upper receiver is the same component used in the complete Super Duty rifle system, which means it is machined to the tolerances and surface finish quality that Geissele applies to professional-grade components rather than to commercial mil-spec minimums. The 7075-T6 aluminum is the alloy specified in the AR-15 mil-spec TDP — stronger and more wear-resistant at the barrel extension threads, charging handle track, and takedown pin holes than the 6061 used in some commercial receivers. Type-3 hardcoat anodize provides the hard, wear-resistant surface finish used on mil-spec and duty-grade components. M4 feedramps ensure reliable feeding with all standard M4/AR-15 BCG configurations. The T-marks are milled directly into the anodize rather than applied as roll marks, providing permanent reference points for accessory positioning. The assembled configuration includes dust cover and forward assist with all associated hardware pre-installed — the builder needs a charging handle, BCG, barrel assembly with muzzle device, and handguard to complete a functional upper. A stripped version is available as part of a Super Duty Receiver Set for builders who want to assemble their own upper parts. The DDC finish matches the Super Duty DDC rifle and pistol color lineup for builders assembling a color-coordinated Super Duty configuration.
