Talley Mfg makes bases as well for both hole spacing. Mine has the .860 rear and wears a set of talleys with throw lever rings and a Talley peep that works great with the factory front sight.
I have owned three M50's, still have two. One .30'06 belongs to my oldest son, handed down to him from his great-grandfather. The other belongs to my youngest son, .270 bought off the classifieds here. Both wear Talley LW's. The pics linked below are the older son's .30'06 wearing the new AA walnut I did for his birthday a few years back. Factory LOP was almost 2" too short for him.
The reference to bad shooters baffles me, too. These will both will hold 1-1.25" for 5 rds with multiple loads and the .270 averages under an inch with the best load we've tried in it, so far. The one I no longer have was the same.
