I change barrels a lot, and I'd like to be able to set barrels to the "same" place. If we assume that the recoil lug is turned clockwise to its stop-very little movement anyhow-I think the recoil lug/nut with one prick punch on the joint and the nut/barrel with another prick would align the bbl/nut/recoil lug/action. BUT, each of the 4, bbl/nut/recoil lug/action must be the same for each setup. Change any 1 and the whole megillah doesn't work correctly.

I'm looking for an easier/better way.
Thanks;
