I posted this in the optics section and they recommend asking in this forum. I have an Yugo under folder M70ab2 and the front and rear sights have little flip-up tabs. From what I've learned so far is that these are the night sights. I just don't understand how they help or change the ability to aim accurately. It actually feels like the from sight hinders the view when flipped up. Can someone explain how night sights work? Thanks Edit: These are not of the actual rifle but exactly the same setup.
