I just bought a M1 for $150.00,
Trying to figure out the maker. All it says on the receiver is
.................................US Carbine
.................................call 30 MI

If it's a USGI Carbine, the makers name will be stamped on the receiver right behind the rear sight.
On some GI Carbines the rear sights over hang the maker's stamp to the point where it's difficult to see it.
The serial number will be stamped behind the rear sight, to the rear of the maker's stamp.

If there is no maker's stamp behind the rear sight, it's not a USGI Carbine, it would be a commercial made rifle.
However, most commercial makers also stamped their name right behind the rear sight.
If it's commercial it may have the makers stamp on the left side of the receiver, possibly below the wood.

Also look for any stamps just behind the front sight. The maker of the barrel usually had a stamp and possibly date there, but that's not necessarily the maker of the receiver.

Somewhere on the receiver will be a maker's stamp and serial number.

A functioning m1 for 150 is a steal, desirable manufacturer would just be icing on the cake. There should be something on top of the reciever to tell who built it.

Yup. I see the Numbers behind the sight now. The maker is under the sight like you said & will need to be removed. I see an I for sure,next letter is either a N or a V.

Rear sights are usually staked in the groove with a centerpunch, what I call a semi-permannet assembly, and I don't recommend removing the sight unless necessary for repair purposes. There is an armorer's tool designed for removing and reinstalling the adjustable sight w/o damage.

"IN--" manufacturer is likely "INLAND" Division of GM. Early WWII carbines were made for the "L" flip sight which did not cover the makers mark. After the adjustable sight was introduced, carbines made after tha date would have the makers mark moved. IF the adjustable sight covers the maker's mark, I would suspect early WWII Inland receiver.

"IV--" could be Iver Johnson (postwar commercial) but I doubt it. Commercial carbines are usually distinctly marked different from military.

I would streatch a thin piece piece of paper over the lettering and do a rubbing with the side of a sharpened pencil point under the sight.

heck, that pile of mags alone might bring close to 150 at the right time and place. You stole that in any condition.

May 3, 2014, 08:39 PM
We have an Inland with the serial numbers 13,8XX.
I tossed a lil flame & then a brass punch, it came right out.

May 3, 2014, 08:43 PM
LOL, a lil more elbow grease has just produced another number. So it's 138,8XX

Oh & Thanks again guys. O

Man, deal of the decade right there! I love my M1 Carbine.

May 3, 2014, 10:23 PM
That photo looks like it was taken back in the 70's! Lol

May 3, 2014, 11:33 PM
Can you take a buncha photos with a digital camera, not a phone, and put those up? Photos of the markings, mag release, other details, and the BACK SIDES of those 30 rd magazines.

Genuine USGI or Korean GI 30-rd mags are good, but there's aftermarket ones that - not so much. The latching nubs on the cheapos aren't much more than pimples. If the nubs are decent sized and well defined, they're probably OK. Compare them to the 15 round mags.

But $150? That was a HELLUVA score! Story?

Yup. I see the Numbers behind the sight now. The maker is under the sight like you said & will need to be removed. I see an I for sure,next letter is either a N or a V.

The original M1 Carbine was built with flip sights that had two apertures. The manufacturer and serial number are just behind these sights on the top of the receiver.

Late in the war, the sights were redesigned to be completely adjustable for distance and windage. Most carbines went through an arsenal rebuild at the end of the war or just after the war and one of the updates was the sights.

Unfortunately, the new sights covered over the manufacturer and serial numbers.

An Inland carbine is definitely a USGI carbine and you got a steal if the carbine functions. Most carbines that I have seen recently start at about $700-$800.

Holy cow, I had to double check the date on the original post. I remember a time when one could acquire an M1 Carbine for at or under $150, but it was a long, long time ago, in a galaxy far, far away. 'gratz.

The story
It belonged to one of the masons I worked with for several years as a kid, Dick passed away about 2 years ago & left his estate to his nephew (no kids or wife) who is also a friend & a brick & stone mason. Anyways Dick left him 2 M1s. Both M1s went to Cabelas.
Cabelas bought the other & passed on this one. The nephew offered it to me for this price about a year ago. Tax return came in the other day,so I bought it.
Now I'm thinking,maybe this was to good a deal & I need to let his nephew no I probably way under payed.
The rifle has some lite pitting & was as filthy as any rifle Ive ever cleaned. I;ll try and get some better pics with this phone. Camera I do not have.

May 4, 2014, 02:14 AM
Very honorable of you to consider offering more money! A total of $500 would still be a good deal for you, but the amount is up to you of course. You wouldn't get hurt for $500 for a USGI carbine and all those magazines.

Hard to tell from that photo, but is that a GI stock? Looks light and shiny. Any cartouches/markings on it anywhere?

May 4, 2014, 02:22 AM
No markings of any kind on the stock,including under the butt plate. The metal tab on the receiver side of heat shield,one of the 2 rivet things has torn loose, easy fix for me.
I'd probably have to give it back. I dont have another 400 to offer. If that ends being the case? I'm charging $50.00 bucks for cleaning this mess. This gun was not well taken care of by any stretch of thee imagination

May 4, 2014, 02:29 AM
Nubs on the three 30 round mags are the same as the 15 rounders, except for 1 extra nub on the left side about an 1/8 below the other two.
two of the 30s have M-2 stamped on the back side,the 3rd has no markings anywhere

May 4, 2014, 03:27 AM
We are at problem #1 already. Firing pin in dose not strike the primer, & if you point the barrel at the ground with the bolt held in the open position, you can clearly see the firing pin drop past the bolt face,180 & you can see the pin drop back inside the bolt. something inside the bolt is broke?

Edit/ just read that it's designed as a free floating F-pin. even in battery after the hammer is dropped, the pin is sloppy.
The hammer, where it strikes the pin, is rounded & looks heavily worn.

Even IF you have to replace a few worn parts, $150 for the rifle with (I count) 8 magazines is a deal. (heck, it's a steal deal, but the original owner I guess was happier with $150 than the rifle).

loose noose
May 4, 2014, 10:23 AM
husker, check the gas piston which is attached to the barrel assembly. Sounds to me like it is loose, just screw it in all the way and re-try it. also check to see if it has any cracks around the piston housing allowing the piston block and piston to come out.

USGI M1 Carbine parts are still available.

Orion 7, Fulton Armory, Riverbank Armory, and Numrich are four places, there are others but these four are ones I know of and could search quickly.

Orion 7 sells an overhaul kit and they are good folks to deal with with good parts.

I'm not sure what parts are getting scarce and are the "Holy Grail" for carbine parts these days.

May 4, 2014, 10:43 AM
An Inland for $150 is a steal. It is worth 3x that in parts alone.

The M1 carbine enjoys quite a cult following on the internet. Pretty much everything you could want to know about it, as well as troubleshooting problems and fixing/replacing parts can be found. I'd start reading at the CMP forum, but there are others with great info at your favorite search engine.

Plenty of real USGI parts available if you need to replace. Read up on Riverbank Armory if you want to do business with them, there are lots of folks who accuse them of selling modern-day parts made up to look like original USGI parts.

this might be of some help:

May 4, 2014, 12:10 PM
I have a sneaky hunch, we have a head spacing problem. Monday i'll look for a SMITH with NO-GO gauges & have it checked. I read CMP had a bunch of barrels that were head spaced wrong & contracted with Under to have a round bolt made for these barrels. any truth to this?

May 4, 2014, 08:50 PM
I got the 30 to shoot. But..... It was double firing constantly & even tripled a couple times.
Dis-connector & new spring ?

You paid a third of the price to make up for it firing three times as much ammo. ;)

I would guess disconnector and spring, maybe a sear and hammer.

May 4, 2014, 10:35 PM
At this point I wouldn't feel bad about the $150 with the intensive cleaning and now the trouble-shooting and parts replacement. It will still be a great deal, just take some TLC. I'd get a new recoil spring while you're at it.

May 12, 2014, 03:05 AM
Ive replaced the trigger group with all new parts as it was shooting 2 to 4 rounds at a pop.
It also shot way right. I noticed the front sight post is way left, the sight itself looks center,but the post looks like it was a crooked when cast, I do believe it's cast iron?
some shop time pics
hammer catch was totally rounded out

Milling time. about to make my own front sight remover

tool is made, I never throw scarp metal away.
