What else could you need? by David Ogden, Verified Owner, October 18, 2021
These are BACK UP sights meant to be used if your optics fail. For those that whine about them being cheap get over it and spend more money if that's what floats your boat. Like everyone else I found the button to be stiff and they didn't flip up wit...
