Ok, this is a naive question I'm sure but I was looking at the PTG bolt heads and saw there was an option for a "bolt alignment cut". What exactly is that?

Older bolt bodies have alignment bump on inside, bolt head had notch on shank that aligned body & head. Could only go together one way. Later models do not have this feature. The bump can be removed to use with bolt heads without notch.
+1, a Dremel and a sanding drum removes the hump very quick.
