The Geissele Automatics Super Duty Assembled Upper Receiver in DDC gives builders the same precision mil-spec upper used across the Super Duty rifle line, machined from 7075-T6 aluminum and finished in Geissele’s Desert Defense Color.

Features:

• 7075-T6 aluminum construction
• Type-3 hardcoat anodize in DDC
• Dust cover and forward assist pre-installed
• M4 feedramps machined in
• Milled T-marks
• Compatible with mil-spec standard AR-15 components

This upper is machined to the tolerances of Geissele’s professional Super Duty component standard rather than commercial mil-spec minimums, using 7075-T6 aluminum for added strength and wear resistance at the barrel extension threads, charging handle track, and takedown pin holes. T-marks are milled directly into the anodize for a permanent reference, and the DDC finish matches the complete Super Duty DDC rifle and pistol lineup for a color-coordinated build. A charging handle, BCG, barrel, and handguard complete the assembly.

Geissele Automatics supplies precision components to U.S. military units and civilian builders, with manufacturing entirely in-house at their North Wales, Pennsylvania facility.
