I am a newbie on this forum who has just purchased a Sport II with the A2 front sight. Planning to zero it this week and picked up a four pin front sight tool made by Wheeler in case the front sight needed any adjustment. Supposed to be a standard sight tool for A2 front sight but it is slightly too big in diameter to fit between the sides of the sight on my rifle. Does the Sport II require a special tool or do I have either a sight or tool that is out of spec? Thanks for any help you can offer.
