If anyone has an M1 carbine, whether it be Maruchin or something else, would you mind posting some measurements? I intend on scratch building the stock rather than modifying an existing one.

Carbine stocks are pretty cheap especially when bought at a gun show. Making your own would probably cost as much in materials, require a lot of work and most likely wouldn't come out as nice. Size wise they are quite tiny and thus far no one has had any luck completing a functional replica that looked right.

Id like to make my own so that i can make it in halves to help me lay out the internals without so much trial and error, or the risk of breaking parts of a full stock.

What is the base gun your going to use? One good thing about making it from scratch is you could make the dimensions larger then the real carbine so it could fit internals that a real stock wouldn't.

Im thinking of using a scorpion gearbox and upgrading it to have a higher fps. I like that its such a small gearbox so i can possibly make it compatible with an m1a1 stock, which i will make of course.

I think we are all anxious to see your results. I've heard over the years that the scorp is the only gearbox that will fit. I for one am looking forward to your progress.

Absolutely! as soon as i get started, I am going to post my progress on all my projects.
One of my biggest problems is living in New York, so I am not able to obtain actual 15 round carbine magazines. I will need to scratchbuild my own magazines out of sheetmetal. Im going to need to find dimensions on them but they should be easy to make because they are a simple box.
I fully intend on starting the build as soon as i get home from this simester in college is over in a few weeks.

Let me see if I can make a decent tracing of my stock and scan it in. (Don't hold your breath. I'm incredibly lazy.)

Why not buy the 10 round mags? you wont need to insert them into the stock, which might make them look the proper size.

Good idea, Although I have never worked on anything RS, and not sure how hard they would be to open up and gut or how time consuming. Many ways to to do it i guess.

The RS mags come apart very easily. You just slide the floorplate out and pull the spring and follower out of the shell. My five round mag sticks out about 1/2 inch, so I'd guess a 10 round mag only partially inserted would be fairly close tot he right length. California doesn't allow 15 round mags, either, but I used to have an empty shell in the garage. I'll look for it.
OK, found it. The 15 rd mag is 3 7/8 in. long. When it's in the gun about 2 5/8 in. sticks out.
Just eyeballing this thing, but it looks like if you removed the feed lips and the lips that hold the floorplate on, an MP7 mag would fit right inside it.

Thanks for the measurements! I found a source of the 10 round mags for a reasonable price, so Ill have to pick up some along with mp7 mags. I have seen reports of aep mp7's with upgrades with a fps from 240 before to 320-330 fps with .24g bbs. So this is looking to be a very skirmishable airsoft gun!

The stock used throughout most of the war was slightly different in shape (as was the upper handguard) than most of the carbine furniture we see available. Volks diagram appears to be the early war stock vs the post war pot belly stock. Unfortunately the earlywar stock is smaller giving one less room to work with.
The scorpian AEP should be adaptable for an airborne version carbine. I keep looking for a used denix carbine replica priced low enough to use as a base component for conversion. No matter how you approach it the component costs add up unless one is able to do their own fabrication. Im doing a conventional carbine conversion using components I had lying around so the risk of loss is quite low and the approach is to create a weapon just slightly more skirmishable than a pistol and could be carried by leaders or team members with other primary assignments like an RTO, runner or crew served weapon guy. ( 300 FPS decent rate of fire.). I started a week ago along with other projects and should know in the next day or so if its a dead end. If it's viable the materials costs will be really really cheap.

Could someone check on an actual ww2 carbine and let me know the measurement from the front tip of the stock to the muzzle? In other words how long is the exposed barrel? I have a brass outer barrel that Im mounting on my conversion effort and while i can eyeball it and probably be about right if someone can give me the correct length that would be great. Obviously the barrel exposure is greater against the handguard / heatshield than the tip of the stock itself which protrudes a bit further. Im looking for the length from the lower stock tip.

Mine measures 7 5/16th inches.
BTW, the stock on mine is a commercial stock I bought back in the 70's. Not sure how it compares to GI issue.

So...7 and 5/ 16ths from the tip of the lower stock? or upper handguard? There is disparity there as you know and I am confused.

That's from the lower stock.

Thanks. You are the man. im glad i asked as "eye balling it" had my barrel about 1 and 1/2 inches too short. Since my shot gun inner barrel ends just beyond the stock itself i hope the route of the bb with hop up is okay flying that far down the new outer barrel? It was fine at 6 inches. If not i may have to deviate some or perhaps install a longer inner barrel? not sure of that will help or hurt the performance.

What i like about the scorpion gear box is that the motor just goes underneath the gearbox, and you wouldnt have to cut away into the grip area which would be very slow knowing it could crack at any minute. What type of wood are you gonna use to make the stock from?
