Welcome the newest addition to our Tippmann Series of TechTTM Upgrades. Since the beginning of time, Tippmann and BT markers have been blessed with amazing RELIABLITY, but cursed with MASSIVE AMOUNTS KICK during their firing cycle. Until now... The Zero Kick HammerTM is most profound performance upgrade you will ever experience in a Tippmann or BT Marker. Using our patent pending MRT TechnologyTM we have reduced the internal moving mass of the bolt assembly by nearly half. Say goodbye to the clunky, kickin' like karate, hand-numbing, operation that you have come to expect from Tippmann style markers. Say hello to a new age of smoother cycling, higher rates of fire, and above all else... WAY Less Kick! Because the Zero Kick Hammer weighs less than the stock bolt, it moves back and forth slightly quicker inside the gun. This movement is typically referred to a marker's mechanical dwell. This means it takes less time from the instant you pull the trigger to the time your ball hits it's target. This means your opponent will have less time to avoid your oncoming ball. This equates to more kills and more kills means more wins. Who doesn't like to win more?
