Rather than spinning the paintball with a spiral rifling pattern, ACP™ utilizes non-traditional straight rifling, to cope with the barrel fouling that comes with rough weather. Once the paintball exits the Freak® XL control bore, it literally rides on rails through the length of the barrel front. Dust, mud, paint fill or rain can literally be blown out of the way into the grooves of the ACP™ rifling, rather than wedging between the ball and barrel wall where they cause off axis spin and hook shots, or worse – binding and breaking the ball in the barrel. Field proven by some of the world’s top players through their development cycle, ACP™ barrel fronts shoot cleaner, faster when the going gets rough. They put more paint on target in less time, which is the Freak® XL’s winning advantage.
