This Mil-Sim 14" (actually 13.5") rifled and gun-drilled barrel is specifically designed for woods and scenario paintball, however it can be used for speedball. The marker has a "Fixed" counter-bored and ported muzzle that is designed to collapse the pressure wave in front of the ball. The Hammerhead Freedom fighter barrel has true Spiral Rifling. Unlike any other HammerHead barrel, the Freedom fighter barrels needs no Fins (bore sizers) because it has a specific thread type and an even .688 bore throughout the entire barrel. With the barrel being one specific bore size, the player will gain a steady & accurate shot. The built-in ported muzzle brake gets the player an even quieter shot! Because these barrels are threaded directly to the marker without a sizer, we recommend you select paint that matches the bore using 0.688 paint for best marker efficiency and accuracy results.
