I have this M1 Carbine I bought around 8 years ago. The receiver and barrel says it is Rock-Ola.
Any advice is welcome.

I don't know much, and I'm certainly no expert. Here is what I notice:

  • The trigger housing is stamped like my Standard Products...no problem, just an observation.
  • The rear sight is the nicer machined type...I have no idea if it's period-correct or original.
  • The top hand guard appears to be a refinished older single-rivet design. No harm or foul there. I preferred the double-rivets, but it's still there (y)

Bores are usually nice in all carbines since there was never corrosive .30 carbine ammo used. Hope it shoots well!

Also, you can get the U.S. M1 Carbines, Wartime Production book by Craig Riesch and have a complete listing of every part of your carbine as originally produced. I stripped down a Winchester I got that was claimed to be all original and correct and every single part was as it should be except a trigger spring that had a couple more windings than it should have had. It's a great book to read through about the history of the production of M1 Carbines.

Stamped trigger housings were made by Winchester. Not all of the manufacturers had the same machine equipment, and that was a work around that ended up working out pretty well. The rear sight is original military, its from the first arsenal upgrade. Later ones were stamped sights, but they both did the same thing. When it comes to M1 Carbines, yours is about as “original” as they get. Most “original” M1 Carbines are force matched. Yours is a very nice carbine, you’ll enjoy it much.

Hmm, stamped trigger guards were designed by IBM and Underwood was instrumental in getting them into production. They were used late wartime production by IBM, Underwood, Quality Hardware, and Standard Projects.

Winchester didn't use stamped trigger housings.

No Rock-Ola carbine left production with adjustable rear sites or bayonet lug barrel bands. Only very late production (serial number above 6,000,000) were produced with round bolts.

I agree, though, you have a very nice post war upgraded USGI M1 carbine.

It's a typical post-WW2 rebuild, and like the rest it is a mishmash of various makers' parts and eras. You're lucky that both the barrel and receiver are still Rock-Ola.

As mentioned already, standard postwar rebuild. Late production Rock-ola could have used the Type IV stamped trigger group. Personally, I wouldn't worry about the parts break down. If it went through the rebuild program (I assume it did with the mix of parts) they would have used what was on hand.

Any import marks? If that were my Carbine if the barrel gauges decent (under a "2" on a CMP barrel gauge is normal, anything lower icing on the cake) I would change the springs and shoot it.

I'm Not calling out this particular post, but many posts on this thread and many others where "the type IV trigger group housing" or the "Garand Type VIIC Left handed scope mount" are ABSOLUTELY meaningless to the OPs. Only experienced collectors with the SAME book can make any sense of such posts. I'm not even sure what the various "types" are unless I dig out the books on the item in question and review them. Milled vs Stamped or grooved vs checkered is usually the limit of my instant recall on these small parts.

The vast majority of M1 Carbines were depot serviced, some more extensively than others. Even ones in excellent condition got some "mandatory updates (bayo lug, safey switch) etc, but a small percentage didn't. That's what makes it fun.

The OP has a nice one.

Good bad or otherwise, at least as far as provenance is concerned. I would say run it till it gets hot and enjoy it. It is not the only one out there. But they are great shooters.

My first Rock- Ola cost me $100. Another GI on the pistol team got his girl friend pregnant, had to raise $$ so got it for cheap back in 73. Had it for many years along with every mfg except IBM. Here’s the first Carbine info book I picked up. Much easier to use than War Baby. Harrison’s book is ok. If one does the math you can about figure what week your carbine was mfg.
