 M1 Carbine parts vs Plainfield 30 Carbine? *Gas nut*

Over the weekend I picked up a Plainsfield 30 Carbine reproduction. (or post war production, whatever you'd like to call it)
After I went to shoot it I realized that it's in single shot mode. So I tore it apart tonight to realize that somebody had completely screwed up the gas piston & nut installation. Whoever had done this put the nut in before the piston and BACKWARDS! The reason they did was because the threads on the nut are obliterated. I think I can salvage this thing with just a new gas nut.

My question is - Can I order any USGI gas nut and it will fit?

I believe all the parts are interchangeable but I wanted to make sure before I spend $15 on a nut from Fulton Armory to find out that it's not the correct thread. I really don't have much in this rifle so if it's a bust then so be it but if I can make it run again it would be a fun little plinker.


Thanks in advance.

Yes, Plainfields use all USGI compatible parts.

Plainfields are my favorite commercial Carbines. I've had several and they were all GTG.

As above, use USGI parts.
