Hello Gents,

If you're using the correct tool, as tight as you can get it.
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.
WARNING!!!! Do NOT try to tighten the nut like your King Kong. IN doing so you can crack the gas housing and no amount of welding or brazing will work. It will just continue to break. The barrel is considered to be gone then and a new barrel is required. Nice and snug, then stake the nut.
