M1 Carbine Problem

I have an Iver Johnson M1. I know next to nothing about it except how to disassemble and reassemble the thing. Had a small problem test firing it, the gas piston nut let loose and the piston destroyed the stock! I ordered a new nut because the old one is very, very loose in the threads. Size difference between the two is almost .014". I'm wondering if someone installed a universal or other manufacture gas nut in the thing. Any insight?
 
Did you order one specifically for an Iver-Johnson, or a generic gas piston nut? Not knowing exactly how your carbine is built makes a difference. Maybe they use a specific sized one, and the one you ordered is a Universal. Or maybe the actual USGI nut is what you got, and they were a different sized one?

That is why the only carbines I own are USGI models, with any USGI part fitting any USGI carbine with no difficulty. Yep, I realize they're a little more expensive these days, but as late as last August you could get them for much less than the cost of a commercial carbine. And if you check the CMP parts sales forum regularly, or watch around most pawn shops or gun shops nationwide, you can still find them quite reasonably priced.

The big advantage is, the old ones have a soul, holding one gives you a sense of holding history in your hands.

Good luck with your issue.
 
I ordered Iver Johnson parts from Numrich. I'm thinking someone some how put a universal or other nut in it. The new nut fits nice and tight, as does the piston. I was just curious as to weather anyone had run into similar problems. I agree with you and holding a peice of history, I tend to like the originals of any gun much better than a remake, and truth be told I'm not at all happy with the Iver Johnson. Very poor quality control if you ask me... Thanks for the reply!
 
Iver M1's were built to mil spec, and GI parts should fit. The gas piston nut should be staked to keep it from loosening, in common use, it is not removed for cleaning.
 
Like I said, watch the CMP boards, and the other places I mentioned, USGI's are still available at pretty decent prices if you watch for them. SOG has been selling Israeli returns for less than prices seen on GunBroker as well. And these re-imports may well have some rarer parts, and are reportedly well maintained.
 
not history

Pretty sure that an IJ M1 carbine is not "history", in that it was not produced during the war years, nor were they used by our military.

The IJ were repro's, made with certain mods, to cut costs. Problems with them are not unusual.
 
Bamaranger, I wasn't sayin a IJ was a piece of history, juat agreeing with Stickhauler about original guns having soul. As this is the first M1 Carbine i've ever touched, i'm really dissapointed with the quality of the remake. I can't wait to get my hands on a real one!
 
sure

Sorry, didn't mean to come across so sharply.

Read a line from an article years ago that the Plainfields and IJ's were good weapons for your enemy to have!

GI carbines were made to a very high standard. Quality control for parts, etc, was very high for all mfg's and GI ammo was non-corrrosive. If not shot out and abused, and foreign corrosive ammo used in them most are still pretty functional.

I had a chance to shoot .30 carbine a good bit during details at the academy and promised myself I would by one, but never have.

Also, about 1983-84, I got a peek into the "armory" at Great Smokey's NP and there were quite a few M1 carbines racked up in the Chief Rangers office.
Why I couldn't say, as the carbine was not described in policy as approved at the time (as I recall, the Rem 760 pump in .308 or '06 was!).

Someday I'll buy a carbine, maybe one of the Auto Ordance models.
 
No worries! I don't tend to take anything the wrong way in a forum setting. Update on the gun, I replaced the nut and piston, blue thread locked 'em and staked the nut in. Head space and all safety/function checks are a go, so next week I'll get out to my range and test fire it (from a lead sled with a string!) Then just got to find a decent stock for it and she'll be good as new, and ready to sell:)
