Custom .30 cal recomendations

[grasshopper257]

I wanna build my own 30 cal but i really need help.

1. what kind of gearbox and or internals should i use.

2. what should i use as the body a paintball kit, a nonfireing replica

3. will i need a machine shop

4 how will the gun get fed. (I dont want a ak47 mag sticking 6 inches out the right)

This all depends on your skill/desires.

Paintball kit or parts kit? The latter would be of course, "better", but would carry a higher price tag. Israeli Browning .30 parts kits can be found for as little as $300, however you must also locate a non-firing receiver.

Gearbox? Well I'm not too skilled with building customs, however it would appear that pretty much any gearbox will fit without too much squeezing considering the size of the weapon.

Feeding? You could probably to a gravity feed like the top M60s....you would need to rework the hop-up and what not to work without using a magazine.

Machine shop should not be necessary.

I'm sure some of the many skilled/experienced forum members can assist you with your project. However....take a look at www.air-sharp.com . The prices are reasonable and their products are supposed to be pretty good. Not parts-kit quality, but much better than any paintball kit.

I concure with the earlier comments except that surprisingly few AEG gearboxes will fit in the 30 Cal housing due to the low placement of the barrel from the 30 Cal reciever group. Converting a real steel parts kit is quite challenging and expensive but when well done results in an excellent field piece and show piece. Scmitty did a fantastic job on one as have others on this board. I'm guessing such an enterprise would be a bargain at $1200.00 if it could be acquired for that and I doubt any one would be willing to build and sell one for that. The killbucket gun is excellent for what it is and frankly I strongly doubt you could build one yourself for the price he sells them for complete and ready to go. I have two of them and I love them. They use the M-14 gear box which is an excellent base gun.

If you can't afford a Killbucket gun I suspect you don't have adequate resources to underatke a do it yourself project of this mnagnitude which will probably cost you more. I think one of a board members is selling his 30 Cal right now for $500.00 which is a real steal.

I built a custom one similar to Schmitty's. I work part time as a tech at an airsoft shop.
All the internals were $100. The demilled .30 was $320 and the ww2 ammo box was $50.

On the M2 tripod. (Without ammo box)


On Mk1 ER tripod.


The box mag holds 3,600-4000 bb's.


A M2 tripod will run $300+, $30-$60 for a pintle, and $100-$150 for a T&E.
I made my tripod, pintle and T&E from scrap steel. Scaled & Fabricated the MK1 tripod from a dozen or so photos.

I will eventually get around to writing a "how-to build a demill .30".

I only suggest building one if you are VERY EXPERIENCED with airsoft guns, good at fabricating and have a lot of spare time.
Otherwise the airsharp .30 is a very good option.

see what i dont understand about using the m14 gear box is how i can use a trigger just like the real steal i dont want a handle and trigger sticking out in the middle of the gun


and how is your custom getting fed gravity? or what?


oh and do you guys think a mg42 would be easier than a 30 cal?

I think based on the simple questions you just asked that this is way way way out of your league. I'm not saying that to sound like an elitist of discourage you from considering moving ahead with this but rather as a sharp warning that things are rarely as staright forward and simple as they appear and custom work with AEGs is frought with challenges. At this stage you simply don't know what you don't know.

All aegs have triggers that simple function in a way that create an elctric contact point. Hence with a relay switch you can place your trigger where ever you want in virtually any configuration. The feed system (That I use) is well explained in the original Killbucket 30 Cal thread. I recommend you step all the way through it from the beginning when he first started his commercial venture. It's an excellent tutorial on the design/ revision improvement process that resulted in his product. His feed system is very clever. It uses a hi cap mag driven by a servo using the same battery as the gun and funneling the BBs through a flexible screen door spring.

Again you're probably going to spend as much to build one yourself as you'd spend buying one of his. I think an MG 42 would be even harder.

I completely agree with 2nd Bat. You would be better off purchasing one from airsharp than building.

Scratch building is a 10 on a 10 scale of difficulty.

I used a 249 gearbox, V3 hopup, and found a way to lay a high-cap down to accommodate more bb's inside a mag.
I showed killbucket how-to build a electric hi-cap mag feed system.

Grasshopper, look at slick's "AK to MG34" post on this forum. That would be a manageable build for a beginner.

Another option is to build an inline vortex "cloud gun" that looks like an M1919. I built one out of brake line, a metal table leg, and MDO plywood about a year ago as a vehicle-mount gun, but mine has spade grips like a Ma Deuce. A vortex gun is gravity-fed and has no moving parts. They fire at a terrifying rate like 2,000 BBs per minute, but they have less range than an AEG with hopup, require a high-volume air source and LOTS of BBs, which pretty much limits them to point defense or vehicle mount. In such capacity, however, they are truly horrifying to assault. Mine is driven by a dedicated air compressor set to 120 psi.

Here's a couple of good links explaining the concept:
