My current understanding is that the BB rolls along the top of the barrel due to the backspin placed by the hop up, in which case it doesn't really matter what size bore so long as it is consistent and smooth.
Wouldn't an upside down V shape "rail" provide better accuracy than a round barrel as there is less contact?

side by side with the same hopup, you won't notice any difference between a 6.23, 6.01, 6.05, 6.08, 300mm, 200mm, 509mm, 650mm, or 150mm barrel in range or accuracy as long as they're all shooting at the same muzzle energy.
Larger bores won't lose accuracy due to fouling as fast as as tighter bores, but they're less air efficient. Larger bores are the best fit for LMGs because you won't lose as much accuracy as the barrel fouls.
Sniper rifles can run 6.01s because they just won't fire enough rounds to foul the barrel in one game.
Fact is, even in real guns, you only extend the barrel when you want more
muzzle energy, and you make the bullets heavier when you want more
range.
Exact same idea in airsoft; heavier BBs are more accurate and go further at the same energy as lighter BBs. Energy is a bit more complex:
The spring is basically what decides your muzzle energy, it has a fixed energy.
You adjust the air volume of the cylinder to balance volume vs pressure so the spring imparts the same energy in BBs whether you're using short or long barrels.
But ultimately, if you have a full cylinder, and you're at your max spring size, then you make the barrel longer and/or tighter to increase energy.
But unlike real firearms, we're capped at around 1.48-1.6j for full auto. So if you can get to 1.6j on a 240mm barrel with the weight of ammo you wanna use, then putting a 509mm barrel in the same gun is just entirely redundant.
Downside to long barrels is the longer it is, the more length you have for something to fuck up.
