Gas Piston

[Garandy]

Regardless of how tight or loose the nut is, the M1 Carbine piston should be relatively free to move. Some are a little looser, some are a little tighter and are affected by things like rust, dirt and I wouldn't be surprised if using lead bullets could eventually gum up the works too.

Hey Garandy,

Thanks for your reply, yeah for sure rust, dirt, and lead would make a difference.

Agreed, I read this again and see you mean the piston, not the nut. I wouldn't worry about the piston as it'll do it's job regardless of whether it's moving with gravity. If in doubt clean it and then don't worry.

Hello Jim,

the usgi nut wrench

That's the only one that works right. Anything else can cause damage.

Amen to that!

(Or you can cut your own out of a wrench socket, but that's a job.)
