Please stop thinking and get your ass to a game. Everyone will be better off.

On this I am out because I obviously have no understanding even though I have made gearboxes which use an over voluming low pressure push I obviously had no idea of physics and just got lucky in creating guns which perform well.
I will also tell people that I can no longer build guns for them because a newb just told me I was wrong and so my expertise is obviously overrated and not worth paying for.
I bow down before you O'messiah of airsoft physics.

Im not gna sit here and argue wv u.
Ill just pretend the barrel has nothing to do with it.
But ill leave you with this.
If barrel length had nothing to do with it then why dont all airsofters and realsteel shooters just use pistols
Thx for the advice and the skeptic comments

Seriously? Why do so many cadets have this snooty 'know it all' attitude. All the information is available to you if you just do a bit of research. All of these people have been very patient and helpful to you and despite this you take it all for granted. I'm genuinely surprised people are still trying to help you.

A.) Real steel is VERY different to airsoft.
B.) A fair few people do "just use pistols".
Just play the f*cking game then figure it out from there.

OK, let's try it this way.
Picture a 6mm 0.2g BB being blown through a hopup unit that imparts all the spin then it travels down a brass barrel and exits at 350fps.
Now picture a 6mm 0.2g BB being blown through a hopup unit that imparts all the spin then it travels down a brass barrel with a slightly different length and exits at... 350fps.
Which BB will fly more accurately and why?
Wrap some plastic and metal that looks like an AK around one of the barrels.
Wrap some plastic and metal that looks like an MP5 around the other barrel.
Will that make any difference to either of the 350fps backspinning BBs?

Thanks, I'm gonna order a 650mm long barrel now for better accuracy!
I mean my gun says 5.56 on the side so it works like a real gun doesn't it?

Airsoft guns and rifled weapons are not comparable. Real guns fire a huge variety of ammunition at very different velocities for very different purposes. An Airsoft gun generates a muzzle energy of about 1 joule and fires a 6mm plastic ball. It is a glorified blowgun.
Regardless of the barrel length that little plastic ball can't leave the muzzle at more than 350fps for a full auto gun. It is possible to generate that velocity quite comfortably in a barrel as short as 100-120mm.
some players are very effective with just a pistol. One of my favourite guns is a full auto M4 pistol that fires 0.25g BBs at 290fps and 44rps, has got about as much range as any other AEG... 110mm barrel.
And the reason we don't all use pistols? The same reason you've spent 7 pages trying to decide what gun to buy.
Bring your sniper/AEG whatever against my TM Mk23, it will out range you.
Lots of people on this forum use a pistol as a primary.
Go to a game, find someone with a 350fps sniper, and put it up against a Firehawk/mp5 at 350fps.
You will then be able to see with your own eyes that barrel length means naff all.

Look ill explain it as best i can amd why i believe barrel length is a factor.
If you have 3 barrels all same diameter working off the same gun same hopup and all are lightly lubricated.
Lets say 10 15 20 inch barrels.
If you put the 10 on youll find the pressure is greater but for a shorter amount of time

U put the 15 on youll have good pressure for longer
If you put the 20 on youll have pressure for longer with a risk of bleed off in the barrel.
If you find the fine line between the 2 longer barrels where you have mimimal bleed you will increase your accuracy and the bb will fly further.
In a simple term if yoy push a car for 5 seconds and let it roll compared to pushing for 10 seconds which will go further.
But if you push too far and get tired you wont have the energy to carry on thus it wont roll as far
How do i know this.
Simple physics. If you can push something for longer without losing the power behind the push you are going to have an increase.
The same can be applied to short and long stroke pistons. A short piston with increased power will only put out the power of its stroke
A longer stroke will have more punch but will need a bigger explosion to increase the speed.
Finding that middle ground WILL give you an increase even if by only a bit you still will have an increase.
Also realsteel and airsoft guns follow the same basic fundamentals. They both rely on a propelling force to move a projectile.
And answering a question with an insult just makes you look really stupid btw

1: Don't ever lubricate your barrel!
2: Regardless of the barrel length the BB has to exit at the right speed. So with a long barrel the 'pressure' has to be lower for longer if the BB is going to be accelerated all the way down the barrel. This isn't as efficient as accelerating the BB harder. It also doesn't generate enough speed early enough for the hop up to impart enough backspin to the BB.
If the BB isn't accelerated all the way down the barrel then at some point there stops being a positive pressure behind it and the lack of air 'cushion' around the BB allows it to contact the bore. It bounces and inaccuracies are introduced.
The physics of Airsoft guns is far from simple. And anything you think you know about rifled guns just doesn't apply.

By using a light lubricant it can enjance the bbs movement. Think about the friction on the bb moving down a dry barrel if it hits the steel it could bounce with lube it wont be so dramatic and you will have a better trajectory.
Im not saying emty a can of oil down there just a very light amount of silicon on your cleaning rag on ur rod will give a slidey surface and less drag for the bb to slow on or change trajectory on and it will create a better seal around the bb meaning more pressure for longer id even say a light amount on the hopup rubber so the contact isnt so dramtic and will help hinder any bouncing down the barrel.
And yes i agree having too much barrel is bad finding the fine line where you still have enough pressure coming out is what will give you an increase and if you can carry all that pressure all the way to the end on a longer barrel through better sealing and what not its going to be much better. Its ok if your indoors only but in the wind on an open field ive noticed you need all the help you can get especially with springers.
