Need some help making a decision.
I have the parts to make an aeg carbine. However there are 2 roads it seems I can take.
1. Using an uzi motor I can make one that will take bbs from magazines. However it will be slightly out of dimension ( about 1/4 inch taller)-probably not noticeable but not exact ( and I am a bit of a perfectionist when it comes to this crap.) Also the bolt would be fixed and not move. But it would take magazines! (also would have a longer barrel than option #2)
2. Using an MP40 AGM motor in the foregrip (ahead of the breech). This would result in a moving bolt but a shorter internal barrel and the magazine would have to be internal too. Mags would be for looks only (Or they can be used to feed the reservoir or serve as a reservoir but when you run out of bbs you wouldn't swap out a mag and the gun would only be a hi-cap. Plus to this method would be the bolt would rack back and forth and be totally cool. (sounding completely authentic when cocking the gun as it would be the entire bolt assembly)
So let me know what you guys think. Both are about the same amount of modification. I am on the fence and don't have the funds to try both.

How many rounds would your second option hold in this internal hi cap magazine and how difficult and awkward would winding and reloading be? I think on a desireable and currently unavailable mainstream weapon like an M1 carbine I'd rather see something that looked as right as possible over one that functioned as closely as possible.
At the gunshow in Monroe today there was a whole table full of cheap carbine stocks and I was really tempted to buy a bunch of them. I looked closely at the limitations presented by the dimensions and decided once again to pass. Good luck Troy with whatever approach you decide to take and let us know how it goes. Where are you planning to put the battery? The stock is obviously too small for a full sized battery. I thought about a small battery inside a carbine stock pouch.
I really want to see someone succeed in doing this as an AEG carbine has been on my wish list for a long time.

hmm, hard toss-up between option 1 and option 2.....I'll leave you to decide. All I know is that I want ro buy one Troy, either way. Seriously.

the best would have been to have materials to build one of each to see which one is the best

Battery would go in the stock and be a 8.4 or 9.6 mini. There is enough room in the stock for it.

Won't the oiler slot interfere? I was thinking a mini battery could fit in a fake dual ammo pouch that was stock mounted or at least be hidden by it.

John,
Good point. Maybe it is the uzi motor as that would leave room for the battery in the forestock.

Although not specifically correct to 'dubya-dubya two', perhaps the so-called 'pot-bellied' stock from the M2 would have enough room up front to fit a mini battery?

I would definetly go with the option that has the least (or no) scale infidelitys. Are you sure either of those (MP40 or UZI gearbox) will fit? I have measured both before and didn't think they would but I don't currently have a Carbine so can't check. Recently someone posted a link to a Asian site with a carbine AEG with what looked like a very highly modified VerIII gearbox. it does have a highcap with a tube in the stock that takes the BB's from the magazine forward to the hop up. I would not worry about the short barrel or where to put the battery. If you can squeeze a gearbox into it, the rest will be easy!

That stunning young chap was me who posted the link. I would love to convert my M1A1 Carbine into an AEG. Troy, please keep us posted. And Schmitty, tackle this as best as you can. I haven't heard from you in ages, where have you been? Sorry, off topic.

101 please repost that link in here because it's more appropriate here than in our British friends thread about his efforts.  I like the looks of it, with the exception of that big-arsed magazine they mocked up- don't like that at all- Like Schmitty says, do it with authentic scale or don't do it at all. I mean if you are going to tackle such a huge undertaking, then the extra effort to make it right will pay off in spades. Take Gryphons $20 dollar Mosin-Nagant for instance- he used the extreme bare-bones materials, yet the weapon still passes a 20, 10 and probably a 5 ft test because it's correctly scaled. |

Thanks for posting it 101, I agree the magazine looks ridiculous on it, but it should be possible to make a low or even high cap that fits the realistic size of an M1 mag. Another puzzle is that the picture of the trigger shows that it uses a micro switch. How would it fire Semi-auto without the mechanical linkage to the gearbox?

Burst chip set to one - a FET timer. Airtronics makes a burst setup which plugs into the gun between the wiring harness and the battery. When the gun is fired on full auto and the burst chip was engaged it would fire a series of shots - which is adjustable via a dial to fire from 1-10 shots (depends on the gun & battery). It is very small about the same size as a stack of 4 nickels. You can also shut the burst off for full auto. There was a discussion about one along with the wiring schematic. forums.airsoftmechanics.com/index.php?topic=651.0I believe if you took the time, you can set the burst fire to 1 and just have a switch to turn it on (for semi fire) and off (for full auto). ///ed/// |

They obviously set it up to use the M-14 magazines which is a shame as otherwise the gun looks great. I like the placement of the battery in the mag pouch. Clearly they are in production and it's a commercial venture. I wonder what they sell for?

In final analysis I will be using the Uzi gearbox. It will be positioned up in the forward stock, and have all the external not needed bits cut off. The fit will be close but up in the front stock strong enough and without changing the dimensions of the stock. I will be making my own stock on this though, like the ppsh to insure a good fit I will make 2 halves and glue together. The feed will have to come from a hi-cap mag. This will allow the bolt to be racked but mag changes will be.....ehhhh. There is simply no practical way to fit both the mag and the motor in that stock. I am considering an internal resevoir of bbs but still not decided on that route. Battery will be in the stock and self made from cell phone batteries. Still waiting on parts so check back around christmas I should have the stock ready to accept metal bits and the motor in place by then. (still gotta put the finishing touches on the grease gun.)

I would use a Lipoly battery. You can get them super slim and long. Instead on a custom battery made from cell phone ones. Which are lipoly.

i don't meant to necropost or anything but what about the internals or batteries from a marui AEP. The other day i took apart my marui mac-10 and I thought, "wow these internals are tiny!" though also after holding an M1 carbine the other day(and wishing i had 650 to buy it) I realized just how small those things are! best of luck!

you would have a problem with the cylinder air volume vs. the inner barrel length

How so? The gearbox could be configured well forward of the mag well in the carbine stock.

of course!
but i wouldn't go that way...using a short aep barrel and gb in a full sized rifle seems just VERY odd to me =P

An aep gearbox just doesn't seem worth it to me. From what I've seen they just aren't powerful enough for even adequate velocty/accuracy/or range to justify it. Thats just my opinion though.

Well it is a Carbine, so I wouldn't see it really needing any power. My question is how would you use magazines with an AEP?

There are already components available to upgrade the AEPs and a slight upgrade in spring and enhanced barrel would do wonders for the performance. If it could be brought up to say 290 FPS with 20 gram that would be more then adequate for a carbine I would think.

Yea, if it were around that range I wouldn't complain, but I'd hate to buy a custom aeg carbine if it performed as well as the average AEP. I think if the "realistic range theory" were approached in airsoft use, it would just lose TONS of range. If a carbine should have the range of an AEP then how far would a thompson be able to shoot (not very much at all). |

I've always a proponent of SMG being limited to what used to be stock performance (around 290 FPS) and with no hop up. The carbine firing at the same FPS with hop up would set it off about right I would think. This is all of course an old debate and probably hijacking the intent of this thread somewhat.
I will own an AEG carbine at some point and it will probably have to be one I build myself so keep us posted everyone on your successes and suggestions. It would seem the airborne version with it's pistol grip would ease some of the fit challenges and open things up to a wider variety of donor gearboxes?

I think 250 fps is fine for a SMG since in real life their range is fairly limited. An M1 carbine should shoot a little farther or harder though. If you can upgrade an AEP gearbox to around 300 FPS I think that would be fine. In my experience short barrels don't neccesarily equal poor or less accuracy. My home made K98 springer only has a 14" barrel but is very accurate.
Realy looking forward to seeing how this turns. Please keep us updated.
Best of luck on this project!

I agree that the length of the barrel has little effect on the accuracy of airsoft weapons especially within the confines of their effective range. Tightbores influence somewaht but not to the extent that most people seem to associate with them. The simple fact is airsoft weapons are frankly not very consistent or accurate. Fortunately at the engagement ranges for airsoft, even 1/4 of an exposed human form is pretty big target. A 14 inch barrel would probably be enough to provide the accuracy one would hope for in a carbine. I am anxious to see some progress in this effort.
