Aw heck Rich, the only stupid question is the one that goes unasked.
Let's start with this. When adjusting front sights for windage you move the sight in the direction you want to move the point of impact. When adjusting rear sights for windage you move the sight in the opposite direction you want to move the point of impact. Thus, you're rifle is hitting to the right so you want to move the front sight to the right.
And yes, the front sight drum is the round thing you've been beating on.
The right side of the rifle is the right side as you are holding the gun as you would shoot it.
A C-clamp is a device that squeezes something as it is tightened. Now if you take a large, regular C-clamp and fit it to your front sight drum and tighten all that will happen is you squeeze both sides of the drum. Nothing happens. But add a 7/16" socket under the side of the clamp that stays stationary and then tighten the clamp screw the screw will still try to squeeze the drum as before but you have a spacer that allows the drum to move instead of bottoming out on the clamp pad.
Thus if you were to put the socket and stationary side of the clamp on the right side of your sight drum (remember, the socket needs to be big enough to fit over the drum) and the screw side of the clamp on the left side and tighten, then the sight will move to the right. If it isn't stuck in place.
The little C-clamp style sight adjusting tool works on the same principle.
One advantage to using a larger C-clamp and socket is you can soak the drum in penatration oil and tighten the thing up as tight as you can. If it still won't move, leave the clamp on tight and wack the screw side clamp pad. The steady pressure and sudden impact should loosen the drum.
Did any of this make sense? Or was it clear as mud?
