I need some help with my new Promag PM290 front sight. This is the detachable, backup iron sight. I'm not an AR expert, but I thought the front post design was supposed to mimic an A2 front sight, and I bought a UTG A2 sight adjustment tool. The prongs on the tool appear to be too thick to fit the notches in the round base of the sight. Am I missing something? Thanks.
