Non-expert here....The M..? I don't know. But I think what you see as a D is actually a P...that is a little faint on the bottom.

P means proofed and M means magnafluxed I believe.

P means proofed and M means magnafluxed I believe.

I heard it was the initials of the arsenal that replaced the barrel.

Don't know for certain.

P is for proof firing

[GPlourde]

Yes, P is a proof.

Your receiver was made in Sep, 1944 by Springfield (see M1 Garand Dates of Manufacture (Born on Date)) and your barrel in Aug 1963 (8 63 stamped on barrel.) I can't tell for sure from the pictures but the butt stock & rear hand guard appears to be birch. It has a T105Ei rear sight (post war) and the receiver appears to have its original finish. Since the barrel dates from almost 20 years after the receiver, it's been through a rebuild at least once. Any markings on the stock?

P means proofed and M means magnafluxed I believe.

That is correct as far as I know.

Every barrel was tested with a high pressure round and marked P to denote that. When it was assembled into a rifle, the whole gun was again tested with a high pressure round, and a prick punch was supposed to be stamped in the loop of the original P to prove it. Under the rush of production, this punch was usually stamped in the general vicinity of the P.
The M is the "magnetic particle test" to detect invisible cracks. Magnaflux invented it.
