The JCS Duel Double Trigger helps eliminate trigger "bounce" and comes in standard black anodised aluminium. The kit includes trigger, trigger guard and the necessary hardware. The marker safety is set by pushing the trigger forward slightly which causes better engagement of the trigger and firing switch. A well set up trigger should not fire when "jarred" or "shaken" or when pointed up, horizontal or down. Please be warned that setup requires some considerable patience and should only be installed by exerienced players or technicians.
