Thank you for the reply.
I am familiar with the Garand barrels having different size gas ports depending on caliber and the use of adjustable gas plugs. Also Mini 14s, with a somewhat similar action, using different size gas bushings and adjustable gas blocks also.
The above is what got me thinking has something similar been tried with the M1 carbine. Never heard that it been done before so thought I had better ask first.
