The Hammerhead barrel is one of the most advance paintball barrels in the industry today. Each barrel is gun-drilled from solid stock aluminum bar and milled on super high tech CNC machines to bring to you exacting tolerances to have the best control over accuracy, sound displacement, and weight. Each barrel is carefully milled and then micro-honed and polished to ensure that these tolerances stay within the exacting standards of our engineers. The Hammerhead barrel was in development for 6 years in order to bring you the best paintball barrel possible. Each Hammerhead barrel has spiral rifling to give you the best accuracy while the muzzle break direct the sound signature backwards away from your opponent. The sound may seem louder to you, the shooter, but get on the business end and you will see what we mean. Add the fins to give you even more control over the accuracy to allow you to match up the bore size with your paintballs.
