8mm conversion?
 

is it possible to convert a 6mm aeg to a 8mm aeg? if so say it was an m4 converted to m16 length or bigger...

You would need an 8mm inner barrel, 8mm hopup, 8mm mags and the nozzle on the gearbox may need to be changed as well. I've been thinking about this recently as well.

Length has nothing to do with it (sounds like something you were getting at).

only problem is the outer barrel inner diameter.. :(

i've been at this point many years ago.. :(

i got to the point of drawing up plans for a new outer barrel for an M4 (match grade bull-barrel style to hide the extra size of the new barrel) but i fell flat at the HOP unit, not enough time.

it would be one hell of a conversation piece!

Question is, why would you want to? I really don't see any benefits to 8mm BBs.

you would be amazed at the phycological impact 8mm bb's have.. after tiny fast-moving 6mm bb's 8mm just seems like golf-balls flying at you.

i had a marushin m1 carbine that was 8mm, had a f*cking sick range at times (it was gas afterall so variable) when using .34's and even the .45's

the benfit would be: Semi-auto only and _small_ magazines or you'll go broke quite quickly (8mm isn't cheap)

Not as easy to get and cost more.... why wouldn't you want to?


Back on track I have to agree with CDN_Stalker's statement. Unless this is just a strange project gun that wont be in play much, or just to say "Hey I did it", just seems like a strange project

well i have the ability to recreate a barret mod body and i figure if i can upgrade the piss so it can shoot really hard i figure a 8mm bb hurts more and get a good distance i can have a semi/full auto 8mm barret sniper gun aeg style.. just thoughts right now though lol.

Who makes a 8mm AEG?

not sure but tinygunner wants to

I know Marushin makes a variety of 8 mm guns, but I don't know of any AEGs. They're all revolvers, shotguns and sniper rifles.

no AEG fires 8mm, and the closest to an 8mm barrett is the old shell-loading smokey's monster.. (8mm, bolt action that ejected the shells that held a single 8mm bb)

bearing in mind that i was once shot across a small room in the back of the hand with that gun and i was only slightly pissed (wasn't wearing eye pro, it was marcus the retarded ex-gunsmith at wolf armouries.. they still have it iirc) rather then jumping around in pain, it's a poor choice unless you like spending a metric f*ck-ton on crap.

this (8mm AEG) is an interesting project but no-one will get it working as well as it could unless they craft a HOPUP unit that will fit the 8mm bb's, and even then it'll be hit-or-miss if it's actually usuable unless it's cranking a fair FPS (remember, the lightest 8mm i've seen is .34)

meh, better to grab one of the marushin 8mm m2 carbines (semi) and rock with that

I would hazard a guess (but it's out of my ass) that the larger bb would be better for longer ranges due to the extra weight (.45+ sure i've seen more) and due to the fact that air bubbles within the bb would have a lower affect on the HOP spin (more mass, less of an imbalence then the same size airbubble was in a .43 6mm bb V's and a 8mm .45)

Smaller BBs will outperform the 8mm BBs regardless of weight, they have less air resistance, are less affected by wind and variable air densities, and are denser. I had some 8mm BBs a few years ago, even the 0.45g felt much lighter than the 0.43g 6mm I compared it to. 8mm DO have a greater surface for lift generation, hop up backspin creates some lift and reduces aerodynamic drag (like a boattail bullet), but those two benefits get cancelled out by all the other cons I posted above.

Hence my asking in the first place. :)

There are no 8mm AEG in existence SYSTEMA fooled around with the idea back in the 90's but it never got more movement than the prototype stage
The only time I see a 8mm outperform a 6mm is a Highly modified Marushin lever action but the cost itself is priced at a very insane price of $4000 USD, as far as a conversion kit there was a kit available made by PDI but I don't think it's available anymore

CDN_Stalker, i fully realise those counter-points but think about how nice it would be if air bubbles didn't cause such a degradation in consistancy...

ok, higher weight (.36's +) would have fewer anyway, but when they do it would still have an impact due to gyroscopic instability.

basically no, there is no great reason for 8mm.. you could also argue that it's more likely to be deflected as well as being more expensive and harder to find.

all i can say is, try being shot at by someone with an 8mm rifle and you'll come to understand why someone would want one (it's a 'hate it until you try it' thing)

I started thinkng about it after seeing the 8mm Glasstards

How about a 8mm glasstards from a MAdbull Nades charged with Co2?

I guess it's more important to point out the brands of 6mm BBs available to us, since you are in Cyprus and are limited to X number of brands, and I've tried everything from Straights to SGM to BB Bastards, and the Bastards are by far the best I've experienced and tested with. The bubble size, count and location is almost virtually eliminated with them as the weight goes up.

Here's a pic I took during my Bastard testing, as you can see, as the weight went up, the bubble structure reduces in size and stay in the center. The 0.36g (no pics) and the 0.40g BBs I've tested after these four weights, literally have no bubbles at all.

and as i have said before..



I was really splitting hairs to give valid but maybe not relevant reasons for 8mm, but a big thank you for that picture, it was very informative! :)

in anything that needs it, i stick to the old stock of grandmasters i have (.29) i need to move onto something a bit heavier, apart from bastards (that i won't be able to get, unless it's a big order due to shipping cost making small orders uneconomical) what would you recommend within the .3-.4 range?

cyprus isn't bad for getting BB's in, just need to ship everything in yourself!

Just run Madbull .43s
They are a really decent BB in my experience.

The mental impact of heavy BBs is fantastic regardless of their caliber.

Even 0.36g from a GBB hitting something solid like a plywood wall near a guy will scare him shitless! I know, I've done it! :D

im thinking a mod from a m4 to make this but caose its a big gun i want big bb's.. i know lots of disadvantages with the whole hop up thingy but if i make a specially designed barrel that can be replaceable to adjust for my hop up i.e moe spin on inside or something along them lines could that bypass the whole hop up deal? pic kinda like this when done hopefully..

turning an m4 into an AS50 is a pretty huge task,

it's skeleton (besides the DSR's bullpup design) looks VERY similar to a DSR -1 that may be a better base gun to build off of,

take the bolt out, hollow out the inside, fit a ver7 gearbox in, take the forestock and cut it down to expose the same amount of barrel etc

Some really basic types of hop up units (fixed ones) have a slot cut in the inner barrel, and use various sizes and thicknesses of O-rings to generate hop up. Minigun comes to mind, as well as 40mm shot shells, the O-ring is positioned to do what a hop up rubber does. Mind you, sealing the breech with the nozzle will give you another issue to sort out, but at least you now know how to put a basic backspin on a BB.

i don't know if you realise the scope of what you're suggesting :P

it's feasable to create an 8mm AEG, but it's basically new territory and i'd only say 'go ahead' to someone with engineering in the blood and alot of experience.

it is very possible that you'd have to machine a new cylinder head and air nozzle, as well as modifying the tappet plate and the front of the gearbox to take the new nozzle.

these are things that could leave you with a 'broken' gun that can't shoot for crap AS WELL AS costing a fortune to fire (ok, with 8mm bastards this is a moot point but it's not going to be a 'cheap' project.

at the end of the day it's your life but be warned, this project sounds like a time and money trap of the highest order.

Just FYI...Marushin also makes a .27 8mm BB. It flies like a whiffle ball without proper spin on it.

Psychological impact? LOL. OH NO AN 8MM BB instead of a 6MM.. RUUUUUUNNNNNN.

i have access to a full cnc machine to help with my computer cuts and whatnot i just need to make spec measurements and an idea on what i need.. then i make and test.. i figure for the price of a new gun whynot make one no-one else has.. and 8mm imo = fear.. and i gonna use it only on semi auto, with the length of the barrell and whatnot i dont want any other issues with barrel suck or nothing..i realize its not gonning to happen in a week or two i expect this project to run me a few months.. when i actually get to the building stage.

We joked about building a Barret .50, shooting 8mm, with each round using a single c02 cartridge as it's reservoir. $0.51 cents per trigger pull. Retarded FPS. Loud as all hell. Smiles a mile wide. :)
