choosing a budget aeg advice wanted

All that happens if you put silicone down an Airsoft barrel is it attracts dirt and you get jams. The BB actually rides on the cushion of air that is trying to blow past the obstruction in the bore. The Bernoulli effect keeps it centred. And if it gets on the hop rubber you lose the grip that allows it to impart backspin. It's another variable that introduces inconsistency. Just check out all the threads that start, "I lubed my barrel and now my gun won't shoot for toffee...."

You seem to have lost sight of the fact that an Airsoft gun is velocity limited. There is also a limited amount of cylinder volume available to blow the BB down the barrel. And there is no argument with the demonstrable fact that I have two guns that are almost identical, except one has a 200mm barrel and the other has a 363mm barrel. The 200mm has a slightly heavier spring and a ported cylinder with the appropriate amount of volume for the barrel and BB weight. The 363mm is similarly optimised. The barrels, hops etc are from the same manufacturer. Shooting the same BBs they have EXACTLY the same range and accuracy.

Pegasus, you are the owner of JustBBGuns and I claim my £5!

firearm bullet say 7.5gms

Vs

airsoft bb say 0.25gms (about 3% of bullet's weight)

propelled by totally different methods with bb requiring magnus/backspin to maintain flight

Airsoft barrels are totally different often they are polished/cleaned bone dry

if any oil or lubricant gets anywhere near the hop bucking it has to be stripped and degreased in washing up liquid

the hop up bucking must be oil free or it won't apply the backspin

the barrel is kept free from oil to avoid risk of contamination

if you was lapping the barrel then silicone oil could be used in the process

BUT for general maintaining your gun NO OIL SHOULD BE USED to avoid screwing up bucking

a few may use a DROP of silicone in the last half of barrel and buffed ultra bone dry - very very carefully

BUT it too easy to screw up and should be avoided at all costs unless you like cleaning up buckings in the sink

tbh - it is more important to use decent bb's than cheap $hit bb's - this can really make a big difference

Honestly - very very little is the same in airsoft as in real steel

(I fired a Desert Eagle in the states and f*ck that kick in airsoft)

airsoft is just toy guns, real steel is uhm real $hit

if we take the car example - like comparing a Sinclair C5 to f*cking Tesla

There is a big massive difference and very little is similar in the mechanics of it all especially on a AEG

(a stfu GBB M4 might have a tiny bit more similarity in the operation but still way different tbh)

Stop thinking - "oh it must be like......"

IT ISN'T - it is a f*cking toy gun not a firearm, so clear your mind a bit

listen to others - seriously this will hold you in good stead

The mind is like a flower - it works best when it is open

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

Actually it is the opposite in airsoft due to "creep"

if you put on a longer barrel almost for sure the fps will increase over the shorter barrel

suffice to say very short barrel guns (MP5k = 110 to 141mm) need a slightly stronger spring to hit 350fps (m110+)

than a longer full length AK47 at 455mm barrel needing a weaker spring to hit 350fps (m95)

There is a bit more to this and cylinder volume has to be taken into account for barrel being used etc....

But in general the fps will increase in a longer barrel though this may place the gun over limits etc.....

Stop over thinking stuff and listen/research more

Urgh.  Please, please understand that airsoft guns are not real steel guns.  Very little of how rifled, propellant based guns works transfers to our glorified blowguns (I love that description).

Both of the guns that you are currently considering until you change your mind again can propel a BB out of their barrels at 350fps.

Both of them can impart exactly the same amount of backspin to a 0.2g BB.

At the moment those BBs leave the barrels, they are both travelling at exactly the same speed, with exactly the same spin.  What happened in the past to get them to that position is no longer relevant to them.  350fps out of a long barrel is the same as 350fps out of a short barrel.  The BBs don't have memory, they only act based on their instant physical properties.

Both BBs are identical. They will fly the same distance, with the same accuracy, and hit with the same force.  You and your targets will not be able to tell which one came from which gun.

 

[L3wisD]

And with the exception of some Pistols (I'm looking at you Glock 19!!)

You can normally hit a human size target easily with any gun at around 22mtrs.

Which is the distance from where I'm sat now, to the building opposite my workplace:

Beyond that... don't worry! Just get closer!

And answering a question with an insult just makes you look really stupid btw

Depends on how stupid the question and the questioner are. In some cases it's almost necessary, take this thread for example.

 

[jcheeseright]

This guy has gone full f*cking retard. 

@commanderpegasus420 - Buy an R85, lubricate the barrel, have a fun time hitting NOTHING all day.   

Then kindly throw the whole thing, and yourself, in the sea. 

 

[Gepard]

Then kindly throw the whole thing, and yourself, in the sea. 

Do let us know how you got on beforehand, though.
