He works at a nearby gun shop, but I tend to agree, stictly speaking ...
When he installed the barrel into this gun, that later broke, he told me he needed to turn the shoulder of the original barrel off, lathe it down to relieve pressure off the receiver, so he could spin the barrel off without risking damaging the extension.
My own receiver vice, which I bought afterwards, (last year), has the receiver shape milled into it, and was provided with a brass shim around the top part, plus came with a brass block to place inside where the bolt would be, to support the sides of the extension against the side pressure of turning. With it I was able to smoothly and slowly spin out the original shot-out barrel from an export 1916, completely undamaged, and no heat needed, and re-install the Bohler barrel.
With a bore-sight laser, I got it oriented north/south, lined up the extractor notches, (the Bohler has no index line) and fine- tuned it to align the sights to the laser poi, using a Mauser P08 front sight pusher. I will be until next week before I can check further, re-check the head-spacing, and actually fire it to precisely adjust the windage.
