Does anybody know what are the M1 Garand Gas Plug specifications? Inner, outer diameter...thread pitch, etc.? Is it a standard size? Thank you.

The one dimension I'm familiar with is the length at .700 max.
Page 128 of Rifle, U.S. .30 , M1 Diagrams & Pictures by Eric Nicolaus
In Zone B-3 of Dwg 7310083
9/16 - 32 NS - SPL
Major dia .5625-.0060
pitch dia .5422 (-0.0030)spl
Minor dia .5242 Max
It is also the same thread as the end of an m1 barrel
9/16 - 32 UN . You can order the tap and die from any good supply company.
I think I paid around $25.00 for both. Steve
If you are in that deep, I suggest getting the Nicolaus book or Kuhnhausen's book.
There are manuals and specs galore in the threads at the top of the M1 page. including complete blue prints.
Seems like you guys know your stuff. What is the best way to tell if a single slot plug is a repo or authentic?
