I will offer you an option that may,or may not work.Way back,when sporterizing milsurps was practical,a lot of bolts were modified.It may be possible to still get a scope modified bolt from Numrich,Springfield Sporters,Old Western Scrounger,Sarco,etc.I would guess the price might be $30 if you can find one.That is cheaper than modding your original,and your original will still be original.
Now,in a perfect world,most of the time the tolerance stack will permit this to work out,but,not always.If you do change bolts,you must check headspace.You might lose,but,it might be worth a shot.
