Trying to figure this out, I have three (two are mine, one confirmed on a friends rifle) AR iron sights that are slightly diagonal to the rest of the sight, and wiggle when turned. Is this normal? I can't find anything on the internet about it. I never noticed an issue with accuracy, especially on the carry handle, but I can't figure out if this is a common thing or not. Top pic is the carry handle, bottom is the detachable sight. Any help is greatly appreciated!!
