Geissele Absolute Co-Witness DDC Micro Red Dot Mount

The Geissele Automatics Absolute Co-Witness DDC Micro Red Dot Mount (Geissele part no. 05-401S) is built for shooters who want their red dot to sit exactly in line with their iron sights. Machined from a single piece of 7075-T6 aluminum and finished in Geissele’s proprietary DDC (Desert Dirt Color) hard-coat anodize, it is sized to the Aimpoint Micro footprint, covering optics like the T-1, T-2, H-1, and H-2. The absolute co-witness height lines the dot up directly behind the front sight post for an instant switch between optic and irons. It is a natural pick for duty carbines, competition guns, and any build where a fast, repeatable zero matters.

Key Specifications

• 7075-T6 Billet Aluminum construction is machined from a single block for maximum rigidity under recoil.
• DDC (Desert Dirt Color) Hard-Coat Anodize gives the mount a tan-toned finish that coordinates with earth-tone builds.
• Absolute Co-Witness Height of 1.93 inches lines the red dot up directly with standard iron sights for instant transitions.
• Aimpoint Micro Footprint fits Micro-series optics such as the T-1, T-2, H-1, and H-2.
• 2-Ounce Weight keeps the mount light without sacrificing the rigidity of a billet design.
• Nut-and-Bolt Attachment applies roughly 1,400 pounds of clamping force for a mount that resists shifting under recoil.
• 3 Shear Lugs add rigidity and help the optic return to zero after being removed and reinstalled.

Frequently Asked Questions
