Default HOLOSUN HS403C

Is there a way to make my Red dot Holosun a true co-witness to my iron sight? I like my backup sight align through the center of the red dot. thanks!

Which mount do you have installed? There's a low mount and a high mount.

The high mount is not an absolute co-witness, Its a 1/3 mount. I'm looking for a mount that makes an absolute and will work with holoson. I never has a Holosun red dot before and didn't know that it cannot just use any standard rail mount. Got it in a trade

This is a picture of the Holosun with high mount. The other one is an absolute co-witness height.

If that's the case, you'll have to get an absolute cowitness mount for it. I believe any Aimpoint Micro mount can be used with a HS403.
