Agreed Jim,
I do understand the need for some cases of R and R of the gas piston and nut, just like the example Eb shared with us about the heavy lead fouled gas cylinder.
But in the article... Where the Author states:
"The reliability of the
M1
carbine has never been a problem."
Further down the Author talks about
A:
"Most jams with the M1 carbine can be traced back to not using a gas piston nut wrench to take the tappit gas system apart for cleaning."
My understanding was the Gas Piston and Nut were to be serviced by the Armorer or at least
not by the regular GI. Likely because of the Nut being Staked.
That said, I'd think most Jams would lead back to:
B: weak Op spring, lack of lube, or dirty.
The most common Jamming or FTF cause we hear about are usually Magazine Related Issues- Some having sagging magazines with worn mag catch nubs. Or Magazines with weak or backward installed springs. And sometimes bent in or out feed edges.
When Troubleshooting: Where Most jams with the M1 carbine can be traced back to... (?)
I'd start with
B over
A first.
YMMV,
