Id say fo with the biggest you can without getting too heavy. Same with the barrel.

For most instances, we will never have any piping too big to decrease performance.

Two feet of chamber should be more than enough for a 4 feet of 2.5" barrel.

And I say to hell with the extra noise and gas consumption.
Make it as long as your barrel is.


This will keep the driving force on you projectile as high as it can be untill it reaches the end of the barrel.
Ofcourse that means a lot of unused power goes to waste too...in the form of more noise and it means longer filling time


so wait...
That would be stupid...Jack's right...

Unless...you would increase the barrel length ..again..and..


Well..you see...there is no ideal lenght...anything from 1-4 feet will do.
