AEG M1 Carbine

[brownien]

Yes I said it. I am going to make an M1 carbine aeg. I just recieved the package last night containing a JG VZ-61 scorpion and a tightbore barrel. After dissassembling it to fix an electrical problem, I discovered that the selector mechanics actually extend down into the pistol grip a bit, so i may need to opt for a mosfet that will allow for single shot operation. I plan on using the lower reciever as is and building a body around it that looks like an m1 carbine. With a 4" barrel on it currently, the range was about 100 feet, and I'm guessing the fps was about 300. I hope that the lengthened barrel will help with the range and accuracy, without much fps problems. I just need to get some overall dimensions and see what I should tackle first!. ;D

Can't wait to see it finished! By the way which measurements do you need for the stock? I forgot to PM you back last time

[brownien]

basically the width and height around the reciever, also if you could get a measurement of how much a 15rd mag sticks out along with its width in both dimensions. Oh! and the outer diameter of the barrel and the distance between the trigger and the back of the mag if you can. Thanks!

[brownien]

Anyone know where I could get a Mosfet to use in my build? I'm not really good with electrical kinds of things and I would like to get one that allows me to fire semi-auto only, without a selector switch wired in, and not have the gearbox bind up. I have realized that with the location of the fire selection mechanisms, I cannot simply move or modify them with any ease. I would like something simple that will hook up in line with the battery and not require too much addition to the gearbox itself.

entire stock length: 29 inches

entire hand guard length: 8 1/4 inches

reciever height: 1 1/2 inches

reciever width: 1 3/4 inches

The trigger guard is basically an inch away from the magazine well. Sorry but I only have a 30 round magazine not the shorter 15 round one, so I can only give you the measurements for that

[tinydata]

I have Carbines and 15rd mags- I'm having a little difficultly understanding your request. Are you basically asking how far the bottom of the magazine protrudes from the stock?

[volkssturm]

Magazine length below the stock, 2 1/2 inches. Length front to back 1 7/8 inches. Thickness 3/4 inch.

[brownien]

Thanks guys! Just what I needed! I was hoping to get accurate measurements, so that I could draw up a rough blueprint, before doing any cutting. I'd rather have everything line-up, and if I need to stretch some small dimensions, I'd rather know about it right off the bat. I'll be doing a 100% scale drawing this week to align everthing, and I will hopefully start cutting some wood for the stock!

[brownien]

I would also like to find a Mosfet that I can use in my build to allow for semi-auto only operation. I admit I know nothing about these Mosfet devices, or how they work really. Is there a mosfet that I can use instead of the standard mechanical fire selection usually in aeg's?

[brownien]

I think by having a way to electronically select semi-auto only will be the only way to easily fit the inner workings into a standard M1 carbine stock. If I am forced to keep the mechancal selector, I may have to go with a M1A1 Carbine, or there will be an ugly bulge behind the trigger Can anyone help? I'd rather not start cutting until I know what model Carbine I can make.

The mossfet is a circuit breaker of sorts it modulates your charge to the trigger switch to minimize the arching that happens when you fire on semi. For AEGs there is greater arching of electricity in smi than in full auto and with rapid repeated semi auto fire over prolonged use the contacts deteriorate. The devices are typically three times arger than a typical fuse holder so with a carbine where space is at premium it is a consideration to plan for. With wiring it can be as remote from the trigge as you'd like so there is some fexibility there.

[brownien]

i think I figured it out, Mosfet wise! Thanks 2ndBat! After reading your post, I did a little more looking and found the burst wizard king kong. It supports, rewiring style application and non. I think I will wire it in line with the battery and use its burst function to select a one round burst I will remove the mechanical fire selection, so the gun is mechanically on full auto perminantly, and let the burst wizard function as the semi auto fire mode with its burst feature. Battery wise, I will re-route the wires to the front handguard and use a small type battery in a space just under the barrel. Just need to get a burst wizard now!

[2nd Bat]

That sounds like the ideal plan. I too just bought a carbine folding stock set up and ordered a scorpian. I am somewhat doubtedful it will be a workable marriage but like the scorpian as it is so if it doesn't work i'm still fine with it. Gaps and exact dimensions will be a little off but t it fits and is reasonable the cz scorpian should make a good base weapon with a few upgrades.

[brownien]

After seeing the UK Arms M1 Carbine springer, I have decided to scrap my plans to draw up and scratchbuild my own parts. I have decided to use the springer as a base gun and put the scorpion internals into that. This way any future carbine builds would be much faster and cheaper to make and possibly sell, but thats another matter! ;D

[jimmiroquai]

Darn. Was waiting for more progress. Not to be a spoil sport but this is why we recommend building first and posting later, in the hopes that there will be less dead ends like this. Anyway, i wish you all the luck on your project, but try actually building it first! Again, i don't mean to offend.

[brownien]

Not at all! I do agree that all the false promises often seen in the form of "I'm gonna do this" can be very dissapointing to everyone here. I was initally hoping that by posting up before I started that I could get some feedback about how I should go about certain parts of my build. But after seeing that springer being offered at a cheap price, and WITH metal (zinc) parts, instead of all plastic, I figured that my prototype aeg carbine would be better off as a testbed for the hybridization of the springer and scorpion.

I do intend on offering aeg carbines if my first carbine build goes well, but that all depends on whether the build is straight-forward, and doesn't cost an arm and a leg to produce and sell! Very few people would be willing to buy a $600-700 aeg carbine! I know that with scratch-building the stock and reciever group, the overall costs would jump right up. I also don't have the money to invest in building them in bulk, like 2ndBat, so they would be built one at a time, based off the knowledge from my first build.

I intend on starting the chopping as soon as the springer comes in next week! I am very excited to have my own and offer my services to anyone who would like their own.

[2nd Bat]

I suspect what you'll discover is a lot of frustrations with dimensions and fitting everything. getting the magazines to seat and feed right etc. Based on your BAR i'm confident you'll find a way to get er done but I am far less confident you will want to sell them at the market price point once you realize all that is involved.

I hope I am wrong as it would be a nice thing to see in the marketplace and would fill a nice hole.

[brownien]

As you will soon find out 2ndBat, the scorpion actually breaks down like an M4 rifle, except with one retaining pin. you remove the forward pin, and slide the upper off, which houses the barrel and hop unit. The lower houses the rest of the internals and the mags will still fit into the lower just fine with the upper off. I plan on modifying the lower to fit, and chopping the upper to fit the barrel assy in. This way i can still use the stock scorpion mags, which I intend to modify the shape to resemble carbine mags, without disturbing where the mag fits into the well. I think that the area between the scorpion trigger and mag are very close to the carbine dimensions, so that shouldn't be an issue. Any modifications I hope to make will be cosmetic, ie. very little need to worry about alignmet of crutial parts like the nozzle and hop unit or mag feed group. This way its much more reliable, and if the internals are too tall or wide, I can simply apply an epoxy bulge or enlarge that stock dimension.

[2nd Bat]

Sounds like you have it worked out. Is the motor in the scorpian angled down into the pistol grip or such that it will work for a regular carbine (which is my preference.)? I have a parastock coming that I intended to use with a scorpian but if a conventional M1 stock might work i'll go that route as well.

As you can see in my basic carbine build i had to create a receiver group that sat up a bit above the stock which the carbine really doesn't but it wasn't as distracting or objectionable a i thought it would be.

[brownien]

The scorpion gearbox should work for both models of carbine as the motor is horizontal as in the new clone BAR gearboxes. This means no hollowing of the pistol grip.

[2nd Bat]

Wow, that is very encouraging. i may have to take my simple build and redo it once again.
