Holosun Absolute Cowitness Mount
The Holosun Absolute Co-Witness Mount is a simple but solid base that sets your micro red dot at the same height as your iron sights on an AR-style rifle. That means when you look through your optic, your irons line up directly in the same sight picture instead of sitting lower in the window. It’s built tough, usually from steel or reinforced aluminum depending on the version, and uses the standard Aimpoint Micro footprint for compatibility with Holosun 403/503-style optics. It’s not flashy at all—just a dependable, fixed-height mount for shooters who want a true “everything lined up” setup.

1. What does “absolute co-witness” mean?
It means your red dot sits at the same height as your iron sights, so both align perfectly in the optic window instead of the irons sitting lower.
