back up sights

This is a glossary of levelling terms. Levelling is a surveying method used to find relative height, one use of which is to ensure ground is level during construction, for example, when excavating to prepare for laying a foundation for a house.

    AR back up sights with fiber optics?

    I'd like to buy some flip up back up sights for my AR15. My eyesight isn't great and I normally use a red dot, so I'd like back up sights with fiber optic rods to help out. Can anyone recommend good fiber optic sights like I'm describing? I can spend $150 or more if I have to. Thanks!
