Don't let that discourage you. 30 carbine isn't an inferior cartridge. If you want to build a carbine in that caliber I suggest you check out the many options available and build an M1. You can build one for about the same price as an AR. That's my next build.http://www.fulton-armory.com/m1-carbine-receivers.aspx

CoalTrain... I inherited an Iver Johnson M1 carbine. Clearly not up to Fulton Armory value. (Boy... they're mighty proud of those huh? $1,499??!!) Would you know if the IJ carbine is mil-spec? I enjoy shooting it and the site you mentioned has plenty of parts if they'll fit. Just wondering.

The history and about anything you could want to know about Iver Johnson carbines.
Hopefully the link will answer any questions you might have.
As to an AR style rifle chambered in 30 Carbine? Won't be easy but if it trips your trigger than run with it.

I think Olympic Arms made a .30 cal US carbine upper for the AR at one time.

Sounds like a hoot! Imagine that baby with a slide fire stock and 50 round drum mag!

Never seen or heard of one but good luck with that expensive project to put an inferi
So, do you mean that it is silly to want to use a round (30m1) that was designed to kill or maim humans, and did so by the 000s instead of using a round that was originally created to shoot 1/2# praire dogs?

I side with Dannyabear.
The .30 carbine, especially in soft-point config, is an excellent defensive round with very good stopping power. Just read Jim Cirilo's accounts of his police career where he used/saw used carbines loaded with soft points on dangerous felons. They never had to shoot a second time, not so with .223/5.56 ARs. Just ask the .mil guys how well that round/weapon combo is fairing in Afghan an Iraq. Not so good.
I'd much rather have a .30 Carbine rifle loaded with soft points over pretty much and AR platform loaded with ANY .223/5.56mm load. Just not enough bullet weight or diameter to get the job done quickly.
I'm interested in seeing if the OP can manage this, I for one think it would be the bee's knees!

Gorsh, Mickey, how come we didn't think of that one??

Hillbillyc would do better to edit the thread title, because it is entirely non-helpful for conveying what he wants to do.
Something like "Can an AR be chambered in .30carbine?", perhaps
===
How about we don't get into the ridiculous round-and-round debate over the effectiveness of .223rem/.30carbine?
Just .... no
If we don't nip it in the bud, someone will be along to tell the old saw about .30carbine being an inferior battle rifle round[1], or how it bounced off of frozen clothing [2] in Korea, or how Vietnam era M16s were really dirty and unreliable [3].
1 - duh, it is a personal defense round, by design - misuse doesn't invalidate it
2 - that's called a "miss" or an "ineffective hit with a FMJ round"
3 - yeah, if you don't clean them and use the wrong powder and don't use the designer's design

I guess the OP seems to have asked about the feasibility of putting together an AR-15 in 30 carbine. However, an alternative to that could be the 300 AAC Blackout.
There would need to be some changes to the traditional 300 AAC Blackout build to make the final product more closely mimic the ballistics of 30 M1 Carbine. For example, instead of loading the traditional very heavy 300 AAC Blackout bullets, load lighter bullets in the 110 to 120 grain range. The change to lighter bullet weight would mean the barrel should be a slower twist. Probably somewhere in the 1 in 14 to 1in 16 range instead of the normal 1 in 10 range. I don't know if 300 AAC Blackout barrels are readily available in those twist rates.
Going this route has some advantages.
1. A normal 223 bolt head could be used. I don't know what would be involved to convert an AR bolt head to 30 M1 Carbine.
2. Regular magazines could be used.
3. 300 AAC Blackout brass is less expensive and increasingly available.
The disadvantages are.
1. Light bullet 300 AAC Blackout loads will be a reloading proposition. I don't believe lighter bullet loads are available in 300 AAC Blackout.
2. Non-standard 300 Blackout barrel twist rate. I don't know if they are available.
A different route to consider. That maybe a little easier to obtain.

Yes, the .300 AAC BLK is the end-all, be-all, carbine round IMHO. All the stopping power of the AK with the noise of a .22 rifle! Gotta love it!
A .30 carbine round AR would still kick buttoony though!

Olympic certainly made a 30 carbine upper. I believe there was an insert for the lower to take M1 Carbine magazines. Has not been in the catalog for a while, they may turn up in the used market. That was about the same time as Taurus had a Raging 30 revolver in the same cartridge; also short lived.

Closest thing I think you will find is the excel arms x-30r. http://www.excelarms.com/rifles/xseriesrifle.html probably cheaper than an m1 actually.........
Alternativly:
You can drop a carbine in a choate stock and put a scout rail on it and get a tactical looking 30 carbine.
Or build an AR in 300aac or 9mm/40s&w if you want to AR platform with pretty similar ballistics.
You would need to try and fabricate a lot of parts to make a 30 carb AR work: custom magwell block, tweaked gas system, new bolt, lighter recoil spring, custom barrel and possibly extension......it would be a mess to try and make.

I have had parts laid out for a couple of years thinking about building
One on a old AK platform that took those 10 rd
Single stack mags .
If i was to build one on a AR platform i might think
About starting with one of those 80% receivers and milling it
For the M1 carbine mags !

ReloadRon.... Thank you!! That Iver Johnson site is excellent. It's good to see that my model is MilSpec too!

Sorry BLU, I didn't check back on my post but Ron took care of you.
I have two USGI carbines. I'm not familiar with Ivar Johnson but I know where to find parts if it's mil spec. I'm rebuilding an Inland right now. I'm going to build another one from parts as I find good deals. Ebay and SARCO has a lot of parts. Another very good resource is the CMP forum's "part's for sale". Fulton Armory is expensive but they have everything you would need to rebuild an M1 carbine.

Unless you're sitting on tens of thousands of rounds of .30 Carbine ammo just getting a .300 Blackout seems like it would make more sense.

Well, yes, I am. I also reload so multiply those rounds! 626 ft. lbs at 50 yards with a 110 grain bullet OUT OF A HANDGUN.... that's enough to hunt deer with. The targets I would have aren't nearly as tough to down! ;-) I'd certainly carry that before I'd grab that .22 rifle the military had me carry.

It probably could be done and it would be a good home defense round. One draw back is the cost of the ammo. .30 Carbine ammo cost the same as other rifle ammo. The gas system might not be adaptable for the round.
As mentioned above the 300BO is probably the better choice if you want something different for the your AR.
The stock 30 Carbine is a great weapon as it is.
