Does anyone have a solid dimension on the pilot end the receiver reamer. I am looking to get some precision ground stock and would like to know what the OD on the reamer is to what is going to fit inside the Bushings. So I guess the ID dimension of the pilot bushings would be helpful. But the OD of the reamer Would get a better measurement I think with a micrometer. So if any one has the reading on that and would pass along the info I would really appreciate it.
