Allot of AKs have canted sights, even some factory Saigas. How bad is it exactly? If it's only a little off you should be able to adjust the front sight post with an adjustment tool to get the sights on target. My 7.62 was canted ever-so-slightly and all I had to do was push the front sight post over about 1mm and it's good to go now.
If it's real bad, and I don't know how it could be, you could try the set-screw method set into a dimple drilled into the barrel under the sight block and stake it on when fully in/flush with the block.
You can also tack weld it. If you ever wanted it off again a little tack-weld shouldn't be easy to grind/drill out.
i would probably have to adjust the front post 3 or 4 mm to the right. Iam going to try to straighten the front sight block out with either a big hammer or wrench later today.
sight block is straight now verified using string from sight leaf to post. Iput the gas block and barrel in the vise and twisted on the front sight post with a wrench and it budged with not too much effort.
