Does anyone have a source for a blueprint showing dimensions for the feeding portion of a mag?  It may sound like a stupid question but while going through my inventory of mags, I found some that the feed lips seem out of proportion.  I would like to get them back to "spec.", whatever  that is......

You will need a pair of dial calipers with a depth guage on the end. When I measure from the top of the back of the magazine to the top of the feedlips it is .220", the space between the feedlips measures .450"- .465".  The mag itself should be between .875"- .890" wide.
