Frequently Asked Questions

What is co-witnessing with an EOTech sight?

Co-witnessing means aligning your EOTech holographic sight's reticle with your backup iron sights. This ensures you have a functional aiming point even if the EOTech fails, allowing you to use the iron sights through the optic's window.

Should I use my iron sights and EOTech simultaneously?

No, simultaneous use is not recommended. For optimal performance and sight picture, you should fold down your rear iron sight when using a functioning EOTech HWS.

How do I get the best sight picture when co-witnessing?

With a proper cheek weld and rear sight folded, aim so the EOTech dot appears slightly above the front sight post. This provides the best field of view and alignment.

Are backup iron sights still usable with an EOTech HWS?

Yes, backup iron sights are designed to be usable through the EOTech HWS window. While the holographic reticle might cover the front sight post, the iron sights remain functional as a backup.
