11.01 Players may use a single .68 caliber paintball marker, which consists of a single barrel and a single trigger system. Double-action triggers are prohibited. Markers will be limited to 15 balls per second, defined as no two consecutive shot maybe timed shorter than 65ms apart. Trigger activation may be stored for up to 100ms after trigger pull but must be cancelled on the next trigger activation (this is to allow guns to shoot at 15bps in semi-automatic mode). Ramping of shots will be allowed only once 7.5bps has been achieved and then the marker may ramp to 15bps only if the 7.5bps is continually maintained. Once the trigger is released only a single additional shot may be discharged thereafter.
