Best performance/value AEG inner barrel
 

As the title says, best performance/value AEG inner barrel. Not interested in the expensive barrels, got a PDI already. Unless there are actual tests to prove they are more accurate, then I will consider them again.

Prometheus EG 6.03. Performance is pretty much the same as PDI. Their tolerance is better, however the PDI manufacturing process is better. These are the barrels I use in all of my guns. If I don't have cash to throw one in, I use the stock barrel until I do.

You question makes no sense. If you understand how barrels were made, you'd know that cost and quality go hand in hand.
The tricky part is weeding out gimmick barrels. Barrels that have higher cost due to some fancy feature that doesn't do anything for you; like miracle barrels.

So basically what you're looking for is the best quality REGULAR smoothbore that will last the longest, which is the prometheus 6.03
No fancy features, nice square hop window for Rhop, nothing but clean and super polished stainless steel in a straight line.

If you want to get detaily, the madbull 6.03 actually performs pretty darn good. Problem is it's aluminum and is super easy to scratch. Big downer is if you ever scratch it (which is 90% of the time), you have to buy a new one, and then you're on par for the cost of a prometheus barrel, but you're still stuck with an aluminum piece of crap.

The PDI 6.05 is good, just not quite as concentric as the prometheus 6.03
PDI 6.08 is crap.
prometheus ASH is crap.
ORGA 6.13 is pretty darn good, the 6.10 is amazing if you have a PTW, the 6.23 is a complete waste of air in HPA guns and you can't even use one in an AEG.
Lonex is a downgrade from even a stock G&P 6.08 brass barrel that's been bent.

What it comes down to is you have 4 kinds of barrels on the market:
-stock
-cheap, either complete shit or disposable barrels
-slightly expensive high quality barrels
-more expensive gimmick barrels that do nothing to improve performance over high quality barrels

And now that we've figured out that you don't need anything longer than a 10" barrel, prometheus barrels really aren't that expensive anyway.
I mean, if you're shelling out the big bucks for 509 or 550-650 barrels then consider the extra $100 to be idiot tax lol

I owned a few Madbull's and I have found after some extensive use, the performance goes down hill.

So my search is for decent SS barrel. Looks like back to a Prom 6.03.

if your stock brass barrel is crooked, a madbull stainless will be good enough for low cost. If you want the best on the market for the price, the prommy eg is hands down the best.

Oh right, I forgot madbull makes stainless now.
I actually Rhopped one and it was not bad as I recall.
HS5 uses the ZCI barrels, but I don't really trust any of his recommendations...

Some people have been experimenting with ZCI barrels on airsoft mechanics. They are all bent, so you need a strong arrow straightener to fix that, then they require a lot of lapping, many hours quite literally, to get them to perform ok. Not worth the trouble unless you are very very low on money but happen to have a whole lot of free time you are willing to waste on lapping.

So you're better off spending the extra $20-$30 on the prometheus barrel to save say 4 hours of work and specialty tooling.
I don't know about anyone else, but the 4 hours alone is worth hundreds of dollars of my time lol

wait, so 10 inch barrel is enough?
i was about to build a dmr with full cylinder air volume and a 455mm prommy barrel, u know, taking the advantage of full cylinder so i can push .30g or .32g bbs.

need your advice about full cylinder question. cuz if 10 inch is enough i'd always go half size cylinders for them.

You would think all dealers would carry only Prometheus or Madbull inner barrels. I see most dealers prefer selling Angry Gun barrel barrels, maybe for other reasons.

Had a look at a Madbull SS barrel yesterday and definitely the Prometheus is so much better in finish and machining quality.

Prometheus EG barrels have been in extremely short supply. I'm not sure what has been happening but if you want one you should buy it immediately.

5" of barrel is enough. In the 400fps range, you really don't need a lot of barrel to get that BB up to speed and centered.
You only need to lengthen the barrel as the muzzle energy goes up, just to have the length to accelerate the BB without using really high air pressures.

The reason I don't run a 16" DMR is because my 10.5" MK18 shoots just as well as any DMR.

As far as "pushing" .30s or .32s, you can just use a ported cylinder for a slightly longer barrel and maintain steady muzzle energy between .20s and .32s on a very short barrel. Or you might even get a bit of joule creep.

TC was this the gas for AEG exclusive, or did it apply a bit to GBB's?

Applies to all platforms.
The shorter the barrel, the lower the gas volume needs to be, the higher the gas pressure needs to be.
GBBR's and P*s start with high pressure anyway, so using longer barrels is inefficient.
GBBRs are just less adjustable since you need to adjust the poppet valve to adjust gas volume. For example; those fools running 14" barrels in their vectors aren't actually shooting much harder than I am with the stock 5" barrel using .30s. They get higher fps on .20s, but joule creep in reverse like crazy, because the gas volume per shot is tuned to a 5" barrel.

In an AEG, the smaller the cylinder volume, the faster the piston hits that compression zone, the higher your initial air pressure will be.

Neat funfact: If your P* is tuned to be air efficient (you're not joule creeping very much switching between .20s and .30s), then the pressure dynamics inside your barrel are almost identical to that of an AEG.

Do you have tests that show a 5" barrel shooting better than a 14" barrel?

They perform the same until fouling sets in. Longer barrels foul faster.
A 650mm barrel will shoot just as well as a 10" barrel until fouling sets in and it can take as few as 100 rounds.
You look at some of the top performing guns out there owned by some of the best techs, and they tend to be under 14" barrels shooting under 2ft groupings at 300ft

If barrel length had an actual effect on accuracy, you'd see a gradual but obvious declination in accuracy going longer or shorter.
But the fact is they perform just as well in the first few shots, but the shorter barrels are more efficient and more effective over a larger number of shots.
If the longer barrels were noticeably better, more guntechs would be running 20" barrels. But the fact is you can get the same performance in a shorter barrel with incidentally less fouling over shots fired.

There's no question that you may or may not see some performance or FPS changes with barrel length, which can change due to platform or whatever. Here's the basic science though: assuming your hop-up is doing what it's supposed to or as good as it can be, from there once your BB stabilizes in the barrel, more barrel doesn't really do you any favors. Longer barrels CAN lower your FPS slightly, foul easier because of moisture or debris, or who knows. Doing side by sides of the same platforms we'd find extremely slight variations in distance and grouping, like a few feet and inches, but then another variation of the same gun would out perform the others consistently with either a longer or shorter barrel. Not by much mind you, but often it makes you see that the barrel isn't the issue, assuming the quality is good and the rest of your gun is good.

I mean very specifically, changing ONLY the barrel length in a setup:
both promtheus barrels
both the exact same hop chamber and rubber
both have the exact same muzzle energy on the same weight of BB
both will perform the same until the longer barrel fouls first

Longer barrels use lower air pressure applied over longer time. Because of the lower pressure, it takes more length for that BB to stabilize. But ultimately, the BB leaves both barrels in a straight line.
One of the things that makes short barrels better IS the higher air pressure, as it evacuates the barrel faster, leading to less fouling.

The ONLY scientific influence that leads to the idea that longer barrels are more accurate, comes from real firearms. But real firearms operate on some VERY different principles when it comes to achieving range and accuracy.
The fact of the matter is that a short little 3" pistol barrel is enough barrel length for a BB to stabilize to the point where it can be extremely accurate at it's maximum range. My won USP compact after getting Rhopped was shooting 6" groupings or less at 160ft. I'll be damned if I could ever get that kind of accuracy without bracing the pistol against something, but the pistol was damn accurate lol
The reason why that's not a very common fact, is because your own personal shooting skill has far more impact on the accuracy of a pistol than the pistol itself.
And unfortunately, the tight groupings don't become really obvious until you're engaging well into the range of the hopup. In the IPSC courses, you're generally not shooting far enough to really need hopup. So it's not a really good shining example of how accurate a pistol can be.

So I just got my Ares G36, stocm is a 247mm inner barrel..
Was thinking of putting a silencer in the gun and replace the barrel with a longer one...

Any opinions

Thanks

What length inner barrels do you run in your personal guns? Prometheus or Lonex?

Lonex barrels are awful. They come pre-fouled.

prommy egs.. in everything I own.

If for whatever reason I can't get one, madbull stainless steel is better than brass, nowhere near the quality of the prommy, but half the price.

And I would take brass over any aluminum barrel, coated or not.

There's really nothing wrong with brass, provided you clean it regularly so it doesn't corrode.
The accuracy on them can be phenomenal, but they get a bad rep just because all stock barrels are brass and tend to be of poor quality.

that's why I mentioned it. Sometimes you'll luck out and get a very straight one.

I talked to my friend today which claims to be a gun doc, and he told me that all you need is a 5" barrel. There is a conspiracy in the industry to sell you carbine length guns and also 500mm sniper rifles. All you need is a shorty AEG or shorty VSR10 with a 10" barrel. Actually you don't even need a rifle, just a pistol.

By the way, his gun is a shorty G&P.

I wouldn't say it's conspiracy... airsoft is full of snake oil products and shady claims of performance through shaky engineering and lack of understanding of the science behind it all.

There's money to be made off fools that hang on your every word.


That's being said, if you want replicas, there's certain lengths of barrels you need to create those replicas. Variety is the spice of life, so having guns of varying lengths makes it more interesting.. functionally it may not have as much use, but it's airsoft.. have fun and buy what you want that will make you look good in photos. lol.

Airsoft is definately full of snake oil, but to be fair, not that long ago a lot of the physics were speculation and the other common tech wasn't up to snuff. So it would've been more likely to see a greater effect changing something like barrel length.

So, don't buy right into any barrel of any length, working on any gun without consequence yet. There are other factors to consider. That being said; if your gun is tuned and hopped properly, dropping from a carbine length to CQB shouldn't hurt anything.

Well there are numerous articles on the internet stating that 400mm to 450mm inner barrel length is the sweet spot for airsoft barrels.

Are your Prometheus barrels genuine?

http://www.airsoftforum.com/board/to...ls/?p=18644696

*is the sweet spot for a full cylinder*
I don't know how or why people interpreted that as 455mm being the ideal barrel length, it's JUST the ideal barrel length for a full cylinder.

Also, just because a gun has a 20" outer barrel does not mean you need a 20" inner barrel. All the systema ptw M16s come with 14.5" barrels

I am leaning towards the ORGA 6.23 for my P*

There are many good reports of the ORGA 6.23 Magnus working very well on P* systems. Did you have problems with it on yours?

The problem is it the only thing it does better than the 6.13 is use more air. The performance is exactly the same

I am using a 6.05 with great results. Do you know if the 6.13 perform even better than the 6.05? I am not concerned about air consumption. With a 68ci 4500psi bottle, I get tons of shots.

Depends how many rounds you go through in a game and how frequently you clean your barrel

Not a heavy shooter. But I do clean my barrel after each game.

Just stick with the 6.05 then
