Winz,
I have a tool all drawn out and ready to go that will provide a straight edge surface that indexes off of the barrel slot at the gas assembly. that way it can be used with bothj shortified and long barrels. This tool is to replace the over 60 yr old, once lasered, Mark 1, eyeballs I am now using to index barrels. that M1E is pretty well useless these days unless it is a very bright room.
PS: the chamber scallops are OK for a rough index, but for perfection we need a better tool.
Anybody want to buy such a tool if |I make more than one??
