M1 carbine aeg

[troyluginbill]

The Aep gearbox would only work on the paratrooper model. Unless I am mistaken the gearbox for the aep extends down into the handle of the pistol and the cylinder compresses to the nozzle via an odd angled chamber. Or is that just the blowback version on the glock 18c? The layout will begin next weekend and the blocking of the stock soon after.

Wait, will you be converting an M1 Carbine or M1A1 Carbine? The Aep as you stated would only work for the M1A1, but would the gearbox you are using for the M1 Carbine work on the M1A1? I am most likely going to follow up on your process on my M1 Carbine if all goes well. So take as many pictures and write down as many steps as possible.

The gear box on the AEP is a simple box without the right angle and quite small. I think it would fit fine. My recommendation would be to buy a CYMA clone and use that to try the concept out.

Guys, I own four Marushin Gas M1 carbines, 1 is utterly US, and I'm looking for an M1A1 Folding stock for one, so I have either two spair M1 stocks, or an M1 and M1A1 Stock without internals, and I have been looking at this question since the beggining of 2007.

Option 1, M1A1 Folding stock, and solid cast externals, with Armalite/AK AEG internals, firing of a Lo cap mag made using Real steel mags and King arms "Real Cap" intenal(a box of ten work out quite cheep). This would mean hollowing out, or possably replacing the pistol grip to accomodate the motor.

Option two was using an M1 Stock, again with cast Externalls, basically using an Upgraded MP7 internals set(longer tight bore barrel, and internal power uprade, along with vented piston head for the longer barrel), and again real steel mag with lowcaps inside.

I havent had chance to play about with these ideas, basically because of work, but I hope this helps.

I think the m1a1 stock will give you more room than anything else. In my carbine at least real steel magazines don't fit, I'm sure they could be modified easily to do so though.

[gliderrider]

Same here, I think that might be deliberate by marushin. If i get this progect off the ground, I would try make it so as little work is done on the original mags as possible, basically design make a new M1 magwell.

[troyluginbill]

Here is the beginning. Half of the stock is cut out to route and do final dimensions and placement. The uzi motor will go up in the front stock and will be upside down. This will get everything in without having to muck around with odd dimensions. Some things to note
1. I am going with making my own stock because I am a cheap bastige. This would certainly work with an existing stock but I can make it look better building my own and I have dimensions from a real carbine to work off of. So don't think you have to make your own stock to try this.
2. The mags......hmmm what to say. There is no gearbox I have run into that will line up with the magwell and fit into the bolt space of an M1 carbine. So there will be a tube carrying the bbs from the mag to the chamber. I figure that if I have a hi cap magazine then the approximate amount of bbs that fit in that and the distance they will have to travel to get to the chamber will mean that mag capacity should be 150-200 actual shots. I can live with that.

The nice thing is once the stock is made and the gear box snugly in place everything will be cosmetic from there on out. The mag feed tube will match the magazine not vice versus so that will be easier to line up. The battery will go into the stock and will be a mini 8.4 that will require taking the sling off to install. But those will have to be the price of owning an M1 carbine aeg.

Some further thoughts:
2nd Batt-what aep motor are you talking about? All of the TM ones are designed to go down the back half of the grip and sit almost vertical to the gun barrel. If they could be mounted horizontal they would be ideal for a carbine (especially now that you can get upgrade parts to give it some oomph.) If you could shoot a link to the model you are thinking of that would be great. The motor would however work fine for the M1a1 as you could mount it in rear grip.

Gliderriderr I hate to burst your bubble but the problem with the carbine as an aeg is that the back is so thin where the bolt is. even with the extra 1/8 inch that a round bolt gives you are still almost 3/4 inch thinner than the front handguard. Any standard aeg motor will have to go into the front stock. The only one other than the uzi that might work for a carbine without major modification would be the version 6 in the P90 configuration. If the magwell is the only problem you have on the marushin gun then I would recommend using a real steel trigger guard. It includes the mag well, mag catch, trigger and guard and could easily be cut to the height you need it to fit with your internals.

Anyway here are some pics of progress:

first the project that was holding me up. Finally figured out the mag problem.


Half the stock with notes on what goes where.


Uzi motor upside down with feed on top. Some bits will have to be removed for final top side fit.


Another angle showing the motor and how it sits in the stock.


Hope to have the motor nestled snugly in its bed by weekend after christmas so more pics coming.

I have a source for carbine stocks for 30 to 35.00 in good shape so if your efforts workout (I'm confident they will) it is a project I've always wanted to take on. I will PM you with a link for the AEP motor which is pretty darn cheap.

The A2 airborne version is always the carbine that to me made the most sense to take on but I'm thrilled to see you taking on the conventional one instead.
i'll be the first one to buy a M1 Para from you

[troyluginbill]

you don't happen to have a cheap source for carbine metal parts too?

[2nd Bat]

Same guy I get my Garand and Springfield parts from. Tell me what you need and odds are he's got it. He's Cye the Garand guy at most of ther shows. Great big older fellow with the cases and bins of parts. His displays have sections on most of the major military US arms but he has way way more then he brings to the shows.

[troyluginbill]

Right now I need a buttplate and screws, trigger guard with the mag release bits on it, and rear sling bar and the top wood cover for the front hand guard. I am going to wait with the bolt stuff until the rest of the gun is done.

[2nd Bat]

I know he has the butt plate and screws cause I have seen them in his bins. The rear sling bar is actually an oiler if you're thinking of the same thing I am and I know he has them. The trigger guard and mag release assemblies I'll check on as well as getting you prices. I'm assuming grade 2 parts are okay? I've seen plenty of the upper handguards.

[troyluginbill]

John,

2nd grade parts are actually ideal. I would be reluctant to use anything that a collectors grade or even good shooter would use. I honestly did not know the rear sling bar was an oiler! Cool idea for keeping an oiler in a stock. The M1 carbine continues to amaze me in its practicality.

On a side note: If anyone out there has a real M1 carbine I highly recommend getting the new hi velocity ammo for it. It really takes care of the issue with the "low power" of the gun. The kick is greater but the impact is BAM! Velocities and impact for it report it at over a .357 in hitting power. Think of it as a .30 magnum load.

Anyways here are the next step pics for the project.

Looking down on whole piece


Another angle


Now I will not be producing these but would anyone be interested in pdf files of how/where to make cuts to make the stock and modify the gearbox?

[TommyGunner]

Hey this is looking really well, if yours is a sucess I might make this my next project...after my BAR and Grease Gun are finished.

TommyGunner

[troyluginbill]

Here is the next batch. Front barrel retaining band is carved is shaped and on. Second half of stock is routed and cut out. Two stock halves have been matched together and taped to begin final fitting. Battery compartment has been carved out with wire chase to motor. Initial cutoff of battery tray on the motor has taken place. Battery will be fit for a mini c cell 9.6/8.4 with mini connector.

Here are current pics

[TommyGunner]

Truely phenominal and caint wait to se the finished internal set up.

[KippySmi7h]

Wow that looks great. Are you planning on selling these? Do you have a price? And Jer, how is the BAR workin for ya?

[TommyGunner]

I at the very least hope Troy continues his picture progression here, simply because that show us alot of info right there on how to build it.

Not to stray off topic but my BAR is going Good Nevil. It is a very time consuming build to say the least and not something I think I will try again after I build this one.

TommyGunner

[2nd Bat]

Troy.

If once you're done you were to send the finished wood to a CnC outfit they could replicate you wood such that any subsequent build would be greatly minimized. Naturally a custom stock maker will add a couple hundred to your cost but I have to believe that's a plus compared to the time required.

It's just a thought. I am really enjoying following your progress and greatly appreciate your efforts.

[troyluginbill]

Got any recommendations on CNC located in WA?

[schmitty]

Looks fantastic!! Very clever idea to make the stock in two halves.

I don't know if John cleared up the AEP gearbox debate but I'm sure he is referring to the gearbox from a TM, MP-7, VZ-61 or Mac-10 (or a Cyma clone). These gearboxes do not have the motor vertical like the Glock or M92 AEP's. They shoot stock at about 255 fps (similar to a stock TM Uzi) and they are quite small.

[gliderrider]

Was their a thread on dropping a Gas M1 into a real steel Paratrooper stock? I cant find it.

[2nd Bat]

There was a discussion about modifying a gas carbine into a para version (Guinness provided it) As for a CnC shop I found one in Yakima and yesterday in talking to my brother he mentioned one in Enumclaw and said they are actually pretty much all over. I imagine someone in Bellingham probably does it as well.

[troyluginbill]

Heres an update.
Finished stock. Only about 2mm taller top to bottom than a real carbine.


Top view with upper handguard in place.


Upper hand guard removed showing some of the modifications to the gear box. Unforntunately these modifications weaken the gearbox so I will reinforce with metal tape and a couple of clips. The forward trigger group attachment has to be removed as well as 2 screw tabs. The fuse hose is also removed but that is a nit.


Here is the feed nozzle. This is the tricky part of the whole project. I will have to run a line from the magwell to this nozzel and hide in in the breech of the gun. For the motor to fit the profile of the bolt the entire gear box needs to be turned upside down. This is fine but for the feed nozzle. The current plan of action should work though and will be the next step.


The nozzle will be ultimately hidden below the handguard and breech.

[azeeze]

Wow that looks pretty damn good.

[Sgt_Tom]

Wow thats lookin good I wanted to try making a Carbine conversion. Was it hard and would you suggest me trying? You planning on selling them.

[troyluginbill]

Actually so far it has not been as hard as I anticipated........there I went ahead and jinxed myself so it should get hard from here on out. (cross fingers behind back). I hope to be getting a combo drill press, milling machine this next week so that things should be even easier for future pieces. I am thinking of making the stocks with detailed instructions on how to assemble. Stocks would come with all the fittings so all someone would have to do would be to buy an uzi for the gearbox/motor and bits and do the assembly themselves. Said kit would be about $300.00 and be geared to put together within a day requiring simple hand tools. Let me know what you guys think.

[YankeeDiv26]

WOW. I think thats awesome. The "partial assembly required" method would be a great way to keep costs down on both ends. Terrific work so-far troy, hopefully the rest of the project will be completed as easy as the first.

[Sgt_Tom]

I guess it's a good price. But I don't buy anything over 150$. I think I might make one of these myself instead of Buying a thompson( I hope Cary didn't hear that lol) What Uzi did you use.

[YankeeDiv26]

Good luck Tom, just remember that Troy makes this look way way WAY easier than it probably is.
