Will a longer barrel improve my accuracy or range?
No.
But they look cool don’t they! Ive secretly always wanted one of those Smart Parts 20″ tacticals for my A5, but i just cant justify it. Instead I own an Apex barrel, which in fact does increase my range quite a bit, but not so much the accuracy. The best way to be as accurate as possible and to achieve optimal range is to buy a barrel kit with multiple bore sizes and learn to arc your shots for distance.
Do longer barrels use more propellant?
Technically, Yes.
The wording of that statement should be revised to be more accurate however. It isn’t the barrel itself that consumes the propellant, it’s the force required to get the velocity of the paintball up to leave the barrel at a healthy 270+ feet per second that consumes more air or c02. As the ball travels through the barrel, its introduced to friction from the interior walls of the barrel. This friction will slow the paintball, however slightly, requiring you to use more force to achieve the same effect as a shorter barrel.
