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.

2. What optics does it fit?
It’s mainly designed for Holosun micro dots like the HS403 and HS503 series that use the Aimpoint Micro footprint.

3. What rifles is it for?
It’s made for AR-15 style rifles with Picatinny rails.

4. Is it adjustable?
No, it’s a fixed-height mount—once installed, the optic height is set.

5. What’s the difference vs lower 1/3 co-witness?
Absolute co-witness lines up directly with your irons, while lower 1/3 keeps irons slightly lower in the window for a less cluttered view.

6. What material is it made from?
Depending on the version, it’s typically steel or high-strength aluminum for durability.

7. Does it add a lot of weight?
No, it’s fairly lightweight, usually only a few dozen grams.

8. Do you need tools to install it?
Yes, basic hex/Allen tools are usually required.

9. Why choose absolute co-witness?
Some shooters prefer it for a direct alignment with backup iron sights, especially for training or redundancy.

10. What’s the main advantage?
It gives you a clean, fully aligned sight picture where your optic and iron sights sit on the same plane for immediate backup reference.
