You know the handle of the cleaning rod is also a front sight adjustment tool? One end slips over the front post and turned to adjust elevation and the other end is a punch to tap on to adjust the windage.
The key to adjusting windage with the punch is to make sure the front sight assy. is solidly supported so full force is transmitted to the sight drum when you tap on it.
