Something you might want to look into if distance is your desire: a Flatline barrel.
You can't better your accuracy so much as you can increase your consistency. You do this by getting a barrel kit in order to have a tighter ball to barrel fit. Freak, iFit, mult-back whatever, etc.
That being said, if you're doing it just for "tacticool" effect or whatever... rock on.
If the barrel fails you, throw a grenade.
