Bart & Cap'n Kraig,
Thx for all your input. Measured front sight and it is at .218 so it is right in the ballpark. I got this M1 from CMP, all new parts including the front sight; ergo, would not have been "altered" in any way. With the front sight at .218, must be the rear sight; you think?
Thx again, you guys are great.
