I've tried fitting dummy 22 TCM cases in the M1 carbine magazine and they seem to fit with Hornady 40gr V-max bullets but they don't seem to be at the right angle -- kind of slightly nose down. Tim, you said at one time that the 22 TCM might be in the future but will it require a custom magazine or will the M1 carbine magazine work -- or require a custom follower?
I like lighter bullets in the smaller cartriges since they get better velocity and the Hornady V-max and similar bullets would work nice also. The factory 22 TCM bullet kind of looks like a little fire plug and may be good for self defense and are inexpensive but for small varmints and target shooting I think the higher grade bullets would make a better choice. Problem is they don't allow the loaded cartridge to fit in the magazine originally designed for the 22 TCM in the handgun. I sure wish there was an answer to this. The small case is just begging to be set up in a DI AR carbine but the factory bullet doesn't seem like the best to use in anything other than the pistol.
The 22 Reed Express gave me the same problems with magazines but I got that worked out but since the 22 TCM used a standard AR bolt with no modification and the ready made brass is available I would think it would make a good DI carbine if it were not for the magazine problem.
I think we are on the right track using M1 Carbine mags for the 22 RE and "real" bullets. The TCM is a slightly longer case and should lend itself well to the M1 mag. yes, we are supposed to be getting a TCM reamer coming.....
I love the 22 Reed Express I have but the forming of the brass is a pain. The brass for the 22TCM is available already made. I think that and the fact that it will work with the standard AR bolt is a plus although it will be hard to beat the 22RE.
Here is our standard "Go To" TCM AR set up. The PPs-43 Mag and adapter.
The rounds feed as nice as the Tokarev and requires minimal lug work. We are trying to get the same ramp geometry on our new set up and are still making parts and testing. The Bolt Hold Open feature works and is a very welcome addition. We got some more stuff going on, but I'll just see how things pan out here this next week, but right now, its pretty cool. I bumped the loading up to 10.5gr of 2400 with a 40gr Nosler and 34gr Dogtown and the primers were just starting to show some flattening so I backed things off to 10.0 gr and function was 100% and the bolt locked back every time.
More positive testing on the 22 TCM with our new TCM mag set up! The Bolt Hold Open function is a very welcome addition and adds to the "Muscle Memory" of the AR platform. Trying to get some more set ups put together to test fit and assembly to get more of these out in the field for work outs. We are also going to work on some 10 and 15 round set up done for the bench shooters so stay tuned and we'll try and keep up with these new set ups.
I bought a m1 carbine chambered in 22tcm. I don't know who or why someone built this but I'm glad to have it. It is very accurate and functions ok. The only issues I have had are magazine related. The factory armscor 40 gr cartridges nose dive in the 30 carbine magazines. Someone mentioned a custom follower? how would you modify a 30 carbine mag to feed better in my custom carbine? Also I thought about buying a chiappa m1-9mm and modifying the mag well and trigger group to fit my para p# 1911 mags. Currently they take beretta 92 mags not sure how different those two mag types are? I think with my 22 tcm barreled action and the stock and trigger group from chiappa I could have something truly great.
An M1 in 22 TCM would be very cool. Yes, the followers would probably need to be worked over as the non-GI ones are all junk. Again, getting the mag set up right is the key. Be careful with 1911 stuff and make sure the mags hold the rounds.
So far I have 2 rock island 1911 mags that work. Each one has been back to the factory to be reworked. So ya mags are hit or miss but you can get good ones it's just a two step process. I think getting those rock island mags to work in my carbine so going to be the best way to go. Just ordered a chiappa in 9 mm. And another magazine adapter from the chiappa factory. I hope there will be enough material in the mag adapter that can be removed to get my 1911 mags to fit. Good scenario has me being able to interchange the 22 tcm action and 9 mm action just like my pistol. Bad scenario has me using beretta 92 mags and 22tcm9r. Worst case scenario has me buying a cheap blow back 9 mm carbine. So I think it will be worth it.
working on my chiappa 22tcm m1 carbine conversion. Progress I have made is a working beretta 92 magwell adapter for the m1 carbine from parts I ordered. I was a pretty good fit with the surplus trigger group. I am thinking the 38super double stack mags are not going to work. As their width from side to side is more of the problem than the length from to back. So I returned the chiappa 9mm carbine and put it towards a rf85 300 blackout that I'm pretty excited about. My next step to to test some 22tcmR9 with beretta 92 mags. 1) I wonder if the 22tcmR is safe in a 22tcm chamber? 2) What kind of loss in velocity will I see out of 16" barrel vs. 5" barrel? 3) can the mag we'll be flared to accept the 38super double stacks? 4) can a single stack 38 super be fitted inside an m1 carbine mag body?
So many questions yet unanswered.... seating rounds forward in the 30carbine magazine instead of towards the back of the magazine worked fairly well as long as you done shake or drop the mag. Chamber is super tight as it got fired I had a lot of fte and took some man strength eject them. Groups were excellent.
So the 9mm m1 carbine adapter does fit but the beretta 92 magazine is too wide by a 1mm. I am not too keen on flaring to mag well on the carbine trigger guard and the chiappa trigger guard is out of stock. I'm not sure any of the other trigger components are compatible.
The para double stack mag is too wide and too long. The para single stack gives an angled feed to the feed ramp and won't chamber.
I am having mixed results with 22 tcm in the stock m1 carbinemags but they appear to function better than the m2 mags when loaded towards the front of the mag.
So my dream of having a semi auto 22 tcm rifle that feeds from para double stack mags seem implausible without machining skills. Why has rock island not developed a semi auto 22 tcm carbine? If I can do it they could do it and a lot better than I have.
22TCM dedicated mags for the AR Hey all, We've been working on these for a while and just ran some mags of 22 TCM (DI operation) with 100% success. The new mags do not need the Tokarev adapter and will handle rounds from around 1.28" to 1.39" in OAL. We are still finalizing the feed ramps and follower geometry, but are taking orders. The initial mags will go for $75 if we can get the followers and springs made easily and we'll offer an upgrade to the early buyers when we make any improvements. We did this for the M1 Carbines and I have not made an M1 carbine adapter since. With these new mags, you won't need the Tokarev mags or adapters ($200) to run your Tok / 22 TCM rounds in the AR any more. Once we get production ready parts, we hope to have a drop in price depending on volume. Right now, all the parts are made in small qty as we get final geometry down. So to summarize: 1. M1 carbine length rounds (1.69" 30 carbine, 357 Mag Rimless) in the AR without an adapter 2. Tok length rounds 1.39"oal Tokarev, 30 Luger, 22 TCM w/50gr bullets, 22 RE) in the AR without an adapter 3. Bolt Hold Open on last round 4. All stock AR lower parts, mag release and BHO. 5.
1. Is this 2 types of mags -- one for the Tok length 22TCM type rounds and an M1 type mag for longer rounds like the 22TCM with 50gr bullets, maybe 50gr V-max type? 2. I like to shoot the Tok round loaded with longer .308 rifle bullets -- will they work in your M1 carbine magazine? 3. What will the mag capacity be? 4. Are you taking orders now and what do you accept for payment. I think you know I have both Tok and M1 carbine mags for my 22TCM but the big thing is they don't do the BHO thing. 5. I also do the 22 Reed Express but need to use a kind of hard to find magazine for them to work in. Will the 22 Reed Express work in your M1 carbine type mag setup.
The 22TCM is a cool little round that shoots great and is easy to do and the biggest problem is always workable mags and looks like you are right on top of it with this project!
