M305 measurement please.

Hi guys, would somebody dig up his caliper and take a precise measurement for me?

I need the outer barrel diameter taken at the bottom of the groove where the op rod guide roll pin goes.

Mmmm...Not clear enough?

In other words, could somebody take his op rod guide off then take his caliper and insert it in the op rod guide pin groove and pinch the barrel please.

Thanks a lot guys.

Barrel spec is 0.732 +/- 0.003 inches diameter
Roll pin hole diameter in the op rod guide is 0.125 +/- 0.004.

Subtract half roll pin hole from barrel spec and you should have a measurement of 0.670 inches, assuming that the roll pin hole lines up pretty good with the barrel groove.

Thanks but it would be great if somebody would actually do it.
