Yep, the gentleman who spins my barrels used to work at Surgeon when they were an Oklahoma company. He's spun up extra barrels for my 1086...HOWEVER, he wanted to see my action to make sure he properly set headspace. They are NOT like an Impact et al. where a prefit from one should spin onto another perfectly.
So chances are, a little machine work might be in order to get them to headspace on someone else's Surgeon action.
