Agrace, I'm with LC on this one. Trying to wrap my head around it hitting left. If your RSB is canted right then that pushes the muzzle right and you should need to push the front sight right to bring the muzzle left.
In your case you are suspecting the RSB is canted right, but you are pushing the front sight left which brings the muzzle to the right.
Seems to me there has to be something else going on here. With the above understanding, if you push your RSB to the left to get it timed up properly then that, by design, should move your POI even further left and you are already out of adjustment on your front sight.
Did you ever try my straight edge suggestion or take a pic from over top? A yard stick will work as a straight edge. Lay it flat with the edge of it on center over the receiver cover then either over center on the globe of the FSB or over center of the bore. For the pic take it far enough back that everything is in focus, but close enough and with hi-resolution so that we can see everything clearly.
I am starting to suspect the barrel was not quite machined right and was installed at an ever so slight angle. If this is the case they may have purposely canted the RSB to the right to line up the sights enough to shove it out the door.
If that is the case when lining everything up with the straight edge the line will be off. Even just on the cover the line will be off from rear to front.
BTW, you can also use a string running tight over the action.
Lastly, as mentioned, if the RSB is canted for whatever reason I would be suspicious of the magwedge lining up properly for use of a scope. The Techsight T-200 may be you best option. Having said that, you won't really know on the scope until you try it. If your scope of choice has enough wind-age adjustment then it will work, but if my suspicions prove correct then the scope will be mounted slightly off center. Kind of like your AK style Russian scope systems.
