Very Very odd question.

Per my experience (which is not much) and all the readings I have done the length of the barrel has to match your piston air output. There is a hole/window on your pistol which is drilled based on the predetermined amount of air inside your barrel. notice that the longer your barrel, the more air it will have inside of it.

To have the best FPS and accuracy you need to go through this check list:
1. Match the air ratio of your piston to the desired length of your inner barrel.
2. use heavier bbs .25g should be good assuming you have to want longer range accuracy
3. check air seals around the piston and inside the hopup
4. use good bucking and hopup

Now to answer your question:
What inner barrel length gives best accuracy and performance?
The simple answer is: does not matter, the physiques behind shooting a BB is different than shooting a real bullet because of the shape of the projectile and the type of rotation they get during the flight.

on a real gun, the longer the barrel the more time you have to give the spin which allows for longer distance. On a airsoft it does not quite hold as the only part that changes the rotation of the bb is the hop up. the rest of the barrel simply works to achieve two goals allowing for the bb to stabalize and for more force to be applied to the bb. the more FPS you have the longer it take for bbs to stabalize but this distance does not increase as much as you expect it.

I suggest that you go for a tight 6.01 barrel instead of a longer one that should give you the performance that you want.
