Hello!

A5 Barrel with Custom Options [BBLTA5*] - $58.00 : Palmers Pursuit Shop!, Where Custom Still Means Something

I want accuracy. Should I get 14" or less (I don't want longer than 14")? No venting or Single Spiral Vent?

Also, I use Tippmann A-5 (offcourse) and mostly Blackbox balls. What bore size do I need?
