Does anyone have a drawing or blueprint of a milspec AR15 lower receiver? I'm looking for something that would show measurements of everything, similar to what someone would use to manufacture a lower.

Thanks in advance!

Something similar to this, but maybe a little less detailed.

I had to search around for this the other day when my grip screw dragged a piece of grit into the threads and buggered it up a tad and I wanted to know the correct size tap to chase the threads .

The pistol grip screw is a 1/4-28 diameter bolt.
